Through the night of 18 July and into the following morning, Churchill remained in close conference with Prime Minister Asquith, explaining what the Admiralty knew, what it believed, and the uncomfortable amount that still rested upon guesswork.
He began with the wider picture, because the wider picture remained reassuring. Across the Empire, the machinery of war was moving much as Britain had expected. The Expeditionary Force continued crossing to France. Supplies followed behind it. Colonial governments were mobilizing men and material, transports were being prepared across the oceans, and plans against Germany's African possessions continued to advance. Japan was being drawn steadily toward the conflict, while the Royal Navy still held an overwhelming concentration of strength around the British Isles.
The Empire was moving, and almost everywhere the machinery of war was proceeding as planned. But one problem was growing more troublesome with every passing hour.
The Atlantic.
Merchant losses were already counted in the dozens. Ships had disappeared with their cargoes and crews, while others remained overdue with no one yet certain whether they were sunk, delayed or hiding somewhere after receiving warnings of German raiders. Churchill warned that if the present rate continued, the total might approach a hundred before the month was over. Shipowners would demand protection. Insurance costs would climb. Parliament would ask questions, and before long the newspapers would begin asking the question Churchill least wanted printed across London.
Where was the Royal Navy?
Churchill nevertheless maintained that the situation could be corrected.
The German surface raiders were powerful, certainly, but they were ships, and ships could eventually be found. Beatty would take Britain's modern battlecruisers westward and hunt them. Nine of the fast capital ships could be divided into three hunting divisions, each working its own broad sector of the Atlantic approaches. They would range quickly, follow merchant reports and use wireless to remain connected across the enormous search area. If one division discovered an enemy, it could engage if circumstances favoured it, shadow the enemy if they did not, and summon the nearest British battlecruisers toward the contact.
The principle was simple. Spread wide enough to find the Germans. Concentrate quickly enough to kill them.
Churchill had considerably less certainty to offer when Asquith asked about the submarines.
Nobody knew their number. Nobody knew their real endurance. Most troubling of all, nobody knew precisely what Germany had built. British experience suggested that submarines were dangerous but constrained machines. They were slow underwater, dependent upon batteries, and eventually had to return to the surface to recharge, ventilate and navigate properly. Once surfaced, they ceased being invisible. A lookout might catch the low shape of a hull, the wake of a conning tower, exhaust haze against the horizon or the unnatural line of a periscope moving through calm water.
The Royal Navy therefore possessed no elegant answer to the submarine. What it possessed instead were eyes, and lots of them.
Cruisers and destroyers would patrol the approaches, shipping routes and coastal waters again and again. Mines and nets would cover places where they could be used effectively. Merchant captains would be warned to keep sharper watches. The hope was simply to fill Britain's surrounding waters with enough observers that sooner or later a German submarine would be forced to expose itself within sight of a British gun.
Once found, Churchill assured the Prime Minister, the problem became considerably simpler. For a submarine caught upon the surface was a fragile thing. Finding it was the difficulty.
Asquith listened, and the longer Churchill spoke, the less sleepy the Prime Minister became. By morning there was nothing tired in his expression at all, only grimness.
Churchill had given him plans. Asquith wanted assurances.
The government had entered the war only days earlier under the assumption that Britain's command of the sea was its greatest certainty. Yet German capital ships were now somewhere beyond Scotland, merchantmen were disappearing and submarines of unknown capability were attacking in waters where the Admiralty had scarcely expected them to arrive so quickly.
Asquith was unwilling to answer that uncertainty with a force merely sufficient for the task. He wanted more.
Churchill's first intention had been comparatively restrained: send Beatty and the battlecruisers, keep the Grand Fleet concentrated, strengthen the coastal patrols and trust British speed and gunnery to do the rest.
By the morning of 19 July, the plan had become considerably heavier.
Beatty would still conduct the hunt. Nine battlecruisers, organized into three divisions of three, would move into separate operational sectors and comb the Atlantic approaches. They were the hounds of the operation—fast enough to cover enormous distances, powerful enough to fight almost anything they encountered, and connected by wireless so that a solitary sighting could quickly become a converging action.
But Asquith wanted something heavier behind them.
Four King George V-class dreadnoughts were therefore detached as a separate reserve, accompanied by several light cruisers and roughly a dozen of the better destroyers capable of sustained operations in northern waters. They would not attempt to follow Beatty's battlecruisers ship for ship. They could not. Their speed made that impossible.
They were there in case the hunt became a battle.
If Beatty found the Germans and could destroy them himself, so much the better. If the enemy concentrated, if several German raiders turned upon one British division, or if Beatty succeeded in holding them long enough for heavier forces to approach, then the dreadnoughts would provide the mass and gunpower to finish the engagement beyond doubt.
The Prime Minister wanted certainty. And in his opinion, four modern battleships were a very British way of providing it.
Churchill considered the commitment excessive. He allowed it nevertheless. Merchant confidence mattered, public confidence mattered, and the sight of some of Britain's most powerful ships putting to sea would send its own message. The Royal Navy was not hiding behind Scotland while German raiders attacked British trade.
It was coming for them.
Even so, Churchill refused to dismantle the Grand Fleet. Jellicoe would retain the overwhelming concentration of British strength guarding the northern exits. Tirpitz might have slipped six valuable ships into the Atlantic before Britain entered the war, but he would not be rewarded by watching Britain scatter the rest of its battle line in pursuit.
Beatty would hunt what had escaped into the Atlantic. Jellicoe would make certain nothing else followed.
Later on 19 July, those decisions had ceased to be plans discussed across tables in London. Orders had reached Scapa Flow, signal flags were rising, boilers were coming to pressure and men were returning aboard with an energy that had been largely absent during the first quiet days of waiting. Since the beginning of the war, much of the Grand Fleet had expected the High Seas Fleet to emerge from Germany and offer them the great naval battle for which they had trained for years. That battle had not come.
Instead, another kind of hunt had been placed before them.
Beatty's battlecruisers began preparing to move west into the Atlantic, not to meet the German fleet in one enormous line of battle, but to search an ocean for the six raiders that had slipped beyond Britain's northern screen. For many of the officers and sailors aboard them, the distinction mattered surprisingly little. They had spent days waiting for something German to shoot at. Now at last they were being given the chance.
Across Scapa Flow, the machinery of departure gathered momentum. Stores disappeared below decks, final inspections were completed, wireless equipment checked and ammunition secured as the great ships prepared to leave their anchorage. The battlecruiser divisions would range ahead in search of the enemy, while the dreadnought reserve and other forces followed according to the Admiralty's wider plan. Britain had decided that the Germans would not be permitted to roam the Atlantic unchallenged.
One after another, the modern British warships began moving out toward the Atlantic.
Farther south, however, the Admiralty's other great response—the attempt to cast a defensive net across Britain's surrounding waters and hunt the German submarines—was proving considerably less impressive.
Along the eastern approaches to the English Channel and the shallow waters facing the Dutch coast, British patrols had been operating since the first day of the war. Their purpose was simple. Nothing German was to reach the Channel without first passing British eyes, particularly while transports carrying the Expeditionary Force, horses, artillery, ammunition and supplies were beginning their movement toward France.
The problem was not that Britain lacked ships. On paper, the Royal Navy possessed them in abundance. The difficulty was that Britain's finest dreadnoughts, battlecruisers and modern flotillas were concentrated farther north with Jellicoe, where everyone still expected the decisive struggle against the High Seas Fleet eventually to take place. The Channel and southern North Sea therefore depended heavily upon ships belonging to an earlier generation.
That did not make them useless. They were never expected to defeat Tirpitz's newest battleships. They were the outer strands of a much larger net: vessels that patrolled, observed and reported, giving stronger forces behind them time to react if anything German attempted to slip south toward the Channel.
Among them were five ageing Cressy-class armoured cruisers—Cressy, Aboukir, Hogue, Bacchante and Euryalus. Built around the turn of the century, they had once been formidable ships. Now they belonged unmistakably to another age. Several had spent years in reserve along the Medway before being dragged back into service, and their crews included large numbers of recalled reservists from Chatham and the surrounding dockyard communities.
Their paint could be renewed quickly. Their machinery could not be made young again.
Almost from the moment the patrols began on 15 July, the old cruisers started reminding their captains of that fact. Days of continuous steaming exposed weaknesses that had been difficult to discover alongside a dockyard. Bearings heated, pumps leaked, boilers demanded attention and engines that had behaved well enough during preparation became temperamental once driven hour after hour through rough water.
The destroyers assigned to support them suffered for different reasons. They were faster, certainly, but speed did not make a small ship immune to the North Sea. Heavy weather threw them violently from crest to trough, buried their bows and exhausted crews who still had machinery to tend and watches to keep. One vessel needed repairs, another needed coal, while another required attention to machinery that could not safely be ignored.
The defensive net remained in place, but its strands shifted constantly.
By the morning of 20 July, the Broad Fourteens patrol had been reduced to three Cressy-class cruisers: HMS Aboukir, HMS Hogue and HMS Cressy.
Their destroyer screen was gone for the moment. Some of the smaller vessels required maintenance, while others had been ordered toward port ahead of another bank of ugly weather gathering to the northeast. Dark clouds could already be seen upon that distant horizon, but immediately around the cruisers the sea remained almost unnaturally calm.
And after five days of war, they had still seen nothing German.
The three cruisers moved steadily across the patrol area called the Broad Fourteens, roughly abreast of one another with Aboukir occupying the centre. Their old engines kept them moving at little more than ten knots, their funnels laying dark trails across the pale sky. There was no urgency aboard them. Lookouts watched the horizon, officers checked bearings and men went through routines that had become monotonous with surprising speed.
Warnings about submarines had reached them.
They knew what they had been told to look for: the low silhouette of a surfaced boat, smoke or exhaust upon the horizon, an unusual wake, a conning tower, perhaps the fleeting needle of a periscope.
The submarines British sailors understood could not remain submerged indefinitely. Eventually they had to surface. Eventually they had to recharge their batteries, ventilate their compartments and navigate beneath the open sky.
Sooner or later, the enemy had to show himself. That assumption had become almost comforting. The British lookouts kept their eyes upon the horizon. They did not look beneath the sea.
And beneath it, U-9 was watching them.
Lieutenant Otto Weddigen remained at the periscope for several seconds longer than necessary, scarcely believing what the optics were showing him. Three British armoured cruisers moved steadily across the calm water ahead, enormous grey shapes trailing smoke beneath the morning sky. They were proceeding slowly, almost casually, one in the centre and the others spread to either side. Their course appeared steady. Their speed could not have been much more than ten knots. Most astonishing of all, there were no destroyers around them.
Weddigen swept the horizon again.
There was nothing: no escort screen, no fast patrol craft weaving around the larger ships, and no sign that anyone aboard the cruisers suspected a German submarine was close enough to study their superstructures through a periscope.
For a moment, Weddigen could only marvel at the absurdity of his luck.
Only days earlier he had been convinced that U-9 might be the most cursed submarine in the Imperial Navy. Germany had entrusted him with one of the finest underwater weapons ever built, assigned him to a wolfpack bound for the English Channel, and almost immediately everything that could delay him seemed determined to do so. Machinery had developed faults before departure. Illness among members of the command staff had cost still more precious time. Then, once U-9 finally reached the open sea, rough weather had pushed her away from the route followed by the rest of her wolfpack.
The others had gone on ahead toward the Channel while U-9 followed behind like a lost pup trying to catch the scent of its pack.
By the morning of 20 July, Weddigen had wanted nothing more glorious than to correct his position, move southwest and find them again before they began their attack upon the British troop routes without him.
And now this.
Three British armoured cruisers, alone. Moving slowly enough to make the firing calculations almost embarrassingly simple.
Weddigen lowered the periscope for a moment and allowed himself the smallest smile. Perhaps his luck had not been poor after all. Perhaps the delays, the sickness and the weather had merely carried him somewhere he had never intended to be because there was something here worth finding.
He raised the periscope once more.
The cruisers were still there, still moving steadily forward and utterly unaware of him. Three great grey ships advancing almost abreast, Aboukir in the centre, their attention divided between the empty sea ahead and the dark bank of weather gathering far to the northeast. Weddigen smiled. If he wanted the greatest possible confusion, the middle ship was the obvious target. Strike one of the outside cruisers and the other two could simply turn away. Strike the centre, and the formation itself would be thrown apart before anyone even understood what had happened.
"The centre ship."
U-9 descended a little deeper and continued forward. Weddigen needed only brief glimpses through the periscope now, raising it for a few seconds to correct the approach before lowering it again. For almost the entire time there was nothing upon the surface to betray the submarine's existence. The three British cruisers were coming toward him as much as he was approaching them, their slow, unwavering course shortening the distance with every minute.
At roughly fifteen hundred metres, Weddigen was satisfied.
"Fire."
Compressed air drove the torpedo cleanly from U-9's bow tube. The weapon settled beneath the surface and accelerated toward Aboukir—more than a tonne and a half of steel and machinery carrying roughly 280 kilograms of high explosive in its warhead. It was far more powerful than anything the British officers above imagined a submarine of this age should possess, and once underway there was remarkably little to betray its approach. Only a faint disturbance marked its passage through the calm water, narrow enough that a man had to be looking almost directly at it to understand what he was seeing.
No one aboard Aboukir was.
On the forward deck, Able Seaman Thomas "Tom" Ellison and Reservist Arthur Price had spent most of the morning staring across a sea that seemed determined to remain peaceful. After several days of miserable weather, the July air was pleasantly warm, their breakfast still sat comfortably in their stomachs, and sunlight broke through scattered clouds to glitter across the water.
Their attention had wandered toward the northeastern horizon, where a dark wall of weather was slowly gathering. Great blue-grey clouds rose high above the sea, their edges catching the sunlight while occasional flashes of lightning flickered somewhere deep within them.
Tom leaned slightly against the rail.
"Look at that."
Arthur followed his gaze just as another distant flash illuminated the clouds.
"Hell of a sight."
Neither man noticed the faint line cutting through the water ahead and slightly off the port bow.
The torpedo ran the final distance unseen.
Then came a dull metallic impact from somewhere deep below, more felt through the deck than properly heard—a strange, hard knock transmitted through thousands of tons of steel.
Arthur frowned.
"What the—"
The world vanished in white light.
The torpedo detonated beneath Aboukir's forward port side with such force that the bow seemed to leap from the sea. Armour and hull plating folded inward, frames twisted apart and compartments nearest the impact were simply destroyed. Flame, steam and shattered metal tore through the spaces behind them. Men eating breakfast moments earlier were killed where they sat; others farther from the blast were scalded, burned or hurled against bulkheads hard enough to break bones and rupture eardrums. On the upper deck, the two lookouts who had been admiring the distant storm disappeared into the eruption of spray and debris, their bodies thrown like broken dolls across the ship and into the sea.
The bridge fared little better. Captain John Drummond was thrown against the chart table, blood running down his face when he dragged himself upright. Around him officers lay stunned among shattered glass and fallen instruments, one clutching a twisted arm while another remained unconscious against the deck. Before anyone could properly gather a damage report, however, the truth announced itself beneath their feet. Aboukir was already leaning heavily to port.
"What in God's name happened?"
Nobody could answer him.
There had been no gunfire, no warning cry and no visible attacker. A mine seemed the most obvious explanation. Perhaps a drifting German weapon had somehow reached the patrol route. Perhaps they had entered an uncharted field. A torpedo crossed Drummond's mind only afterward, and even then the violence seemed almost too great. He knew what torpedoes could do in theory. He had never watched one nearly tear the front from an armoured cruiser.
Outside, Hogue and Cressy reacted instinctively. Both broke away from the stricken centre of the formation, turning outward while their lookouts searched the calm North Sea and their guns swung toward anything that seemed remotely suspicious. Signalmen demanded answers from Aboukir. Officers searched for mines, wakes, a conning tower, a periscope—anything that could explain what had happened.
There was nothing.
Only Aboukir, settling lower as smoke and steam climbed from her wounded side.
The order to abandon ship followed quickly. By then the list was already making an orderly evacuation difficult. Boats were lowered at awkward angles, some striking the hull or hanging uselessly from tangled falls while men jumped directly into the water rather than wait. Others remained aboard too long, convinced the cruiser might stabilize.
She did not.
Within minutes the great ship rolled farther onto her port side. Men slid across the deck, clung desperately to rails and fittings, then disappeared into the sea as Aboukir finally turned over. Hundreds were left in the water around her overturned hull—some aboard boats, many clinging to timber and wreckage, others simply trying to remain afloat in heavy uniforms and boots while wounds and exhaustion worked against them.
At a distance, Hogue and Cressy continued circling. Nothing attacked them, nothing surfaced. The sea remained calm enough to make the whole disaster seem impossible.
For nearly twenty minutes they watched and waited, still uncertain whether Aboukir had struck a mine or whether some unseen submarine had already escaped. But as the minutes passed, men in the water began to die. A flare climbed weakly above the wreckage. Cries for help carried across the sea. Wounded sailors slipped from pieces of timber and vanished beneath the surface while others screamed for the cruisers to come closer.
For the men aboard Hogue, those voices were painfully familiar. Many of the crews came from the same Chatham and Medway communities. They had served together, drunk together, attended the same churches and passed one another on the same streets. Nicholson was not watching strangers drown.
Eventually he could bear it no longer.
"Take us in."
Hogue turned toward the wreckage.
The cruiser slowed as boats were lowered and men crowded the rails with ropes ready. Soon small craft were pulling survivors from the water, and for several minutes it appeared that the danger had passed. Half-drowned men were dragged aboard by their sleeves and collars while others were hauled into boats from among the wreckage.
Then Hogue slowed almost to a stop.
Beneath her, U-9 had never left.
The submarine had moved silently beneath the confusion, changing position while Weddigen watched the British circle their dying sister. Like a wolf lying still beyond the light of a campfire, he had simply waited for one of them to come within reach.
Now Hogue filled his periscope, twelve thousand tons of British steel sitting nearly motionless less than a kilometre away.
Weddigen needed no elaborate calculation.
"Two tubes."
The order passed quietly through the submarine.
"Fire."
Two torpedoes slipped from U-9 in quick succession.
At such short range, Hogue had only seconds.
A lookout finally caught sight of the wakes racing toward the starboard side. He stared for one heartbeat before understanding what they were.
"TORPEDOES! STARBOARD!"
The alarm swept across the deck. Engine telegraphs rang and Nicholson ordered power ahead, but the old cruiser had barely begun to move when the first torpedo struck.
The second followed almost immediately.
The twin explosions tore into Hogue amidships. The cruiser seemed to rise beneath the blows before crashing back into the water, her centre disappearing behind spray, steam and flying steel. Machinery foundations ripped loose and entire compartments collapsed inward.
Then the ammunition caught.
A deeper explosion erupted through the heart of the ship.
Flame blasted upward through the decks. The bridge disappeared behind fire and shattered glass, killing Nicholson and the officers around him almost instantly. Boats hanging from their davits were ripped apart, while those already in the water were thrown sideways by the violent surge rolling away from the hull. One rescue craft capsized. Another was struck by falling debris and broken apart among the men inside it.
Hogue's centre folded.
Her back was broken.
To the survivors of Aboukir, it was almost impossible to comprehend. The ship that had been coming to save them was suddenly burning and collapsing in front of their eyes. Bow and stern sagged at different angles as smoke poured from the ruined middle, and men who had only just been rescued found themselves thrown back into the same water from which they had escaped.
Within minutes, Hogue was gone as a fighting ship.
The North Sea around the wreckage became a mass of overturned boats, bodies, burning debris and men screaming over one another for help.
And now Cressy stood alone.
By then there could be no comforting talk of mines or accidents. Somewhere beneath that deceptively calm sea was a German submarine, and Captain Robert Warren Johnson knew it. He ordered his guns onto the water, and for several minutes the old cruiser fired wherever a lookout thought he had glimpsed a periscope, a strange ripple or a shadow beneath the surface. Shells threw white towers of water into the air while smaller guns joined them, hammering empty patches of sea in the hope that one lucky shot might find the invisible enemy.
None did.
U-9 had already moved.
Eventually the firing slackened. Cressy remained under way, circling the wreckage while every available pair of eyes searched the surrounding water. Ten minutes passed without another torpedo. Nothing surfaced. Nothing moved. There was only wreckage, smoke and hundreds of men struggling in the water between the remains of Aboukir and Hogue.
Johnson knew exactly what prudence demanded.
Keep moving. Do not stop. Wait for destroyers.
Then, through his binoculars, he saw John Drummond. The captain of Aboukir was somehow still alive. Johnson recognized him almost immediately, clinging to a narrow piece of floating timber while trying to keep a wounded sailor above the surface. Another terrified man had seized the same plank and was pulling himself against it with enough desperation to threaten all three of them. Drummond, bleeding and exhausted, was trying simultaneously to support one man, calm another and keep his own head above the water.
For Johnson, that changed everything.
Drummond was not merely another officer in another ship. They had known one another since their younger naval days, had risen through the same service and shared the peculiar closeness of men whose careers repeatedly crossed over decades. Other officers upon Cressy's bridge recognized friends as well. Sailors along the rails pointed toward faces in the water—men they had served beside, grown up beside, attended weddings with or passed in the streets of Chatham before the war.
It was one thing to understand that approaching the wreckage was dangerous.
It was another to stand safely upon a deck and watch people you knew drown.
Johnson lowered his binoculars.
"Take us in."
Nobody argued.
Cressy turned toward the survivors, though Johnson refused to make the approach carelessly. Her engines remained running, guns stayed loaded and lookouts were ordered to watch every quarter of the sea. The cruiser came close enough for the boats to be lowered quickly but not so close that the wreckage itself endangered her. Sailors crowded the rails with ropes and lifebelts while the first boats began descending toward the water.
For several moments, nothing happened.
The boats touched the sea and pulled toward the nearest groups of survivors. Men aboard Cressy shouted encouragement while others prepared to haul the wounded aboard. Johnson remained upon the bridge, still scanning the water.
Perhaps the submarine truly had gone. Perhaps ten minutes of maneuvering and gunfire had frightened it away.
Perhaps—
"TORPEDOES!"
The scream came from starboard.
Johnson turned.
Two pale wakes were racing toward them.
"Hard to port! Ahead full!"
The engine-room telegraphs clanged. Cressy's propellers churned harder, and the old cruiser began dragging herself into the turn. Half-lowered boats swung violently against the hull. Men fell. One boat struck the plating hard enough to throw several sailors into the water.
The first torpedo passed astern. A cheer barely had time to begin before the second struck almost directly amidships.
The detonation tore into Cressy's underwater hull with tremendous force. The cruiser lurched sideways, her deck rising beneath the men standing upon it as steel, water and fire erupted through the centre of the ship.
Then something inside answered the blast. Ammunition detonated, and the second explosion was catastrophic. Fire punched upward through the decks and swallowed the bridge. Johnson and the officers around him disappeared almost instantly behind flame, shattered glass and fragments of steel. Men waiting beside the boats were hurled outward with them. Several half-lowered craft were ripped from their falls and flung across the water, their occupants tossed about like stones before the boats smashed apart.
Cressy's centre seemed to burst open.
The blast did not spare the men already in the sea. The pressure rolled outward through the water, stunning those nearest the cruiser and forcing others beneath the surface. Debris rained across the wreckage field. Jagged pieces of steel fell among boats and swimmers; one heavy section crashed directly through a crowded rescue boat, breaking the craft apart and killing most of the men inside before they could even understand what had struck them.
Smoke and fire climbed high enough to be seen far beyond the immediate battlefield.
The cruiser did not linger.
Her broken centre sagged almost at once, the bow and stern settling at different angles as the structure between them failed. Men still alive below had almost no time to reach the upper deck. Others were trapped by collapsed passageways, fire or flooding that spread faster than any damage-control party could contain it.
Within minutes, Cressy was gone. And with her went most of the men who had still been aboard.
Three British armoured cruisers had occupied that patch of the North Sea less than an hour earlier. Now there were none.
Only wreckage remained—boats, timber, oil, scraps of clothing and hundreds of human beings scattered across water that looked obscenely peaceful beneath the morning sun. Smoke drifted across the scene while the distant storm clouds still gathered to the northeast, indifferent to what had happened beneath them.
Men shouted for help until their voices failed. Some prayed. Others called names into the wreckage. The wounded disappeared first. Men too badly burned or broken to swim slipped beneath the surface. Others held themselves above water by pieces of timber until exhaustion loosened their fingers. Those stunned by Cressy's final explosion sometimes sank without struggling at all. The sea continued taking them long after the shooting had stopped.
Below the surface, U-9 was already leaving.
Weddigen had no reason to remain. He had expended several torpedoes, drawn heavily upon his batteries and placed enough strain upon machinery that had already troubled him before departure. British wireless calls had almost certainly gone out, and sooner or later destroyers would arrive.
He had achieved more than he could reasonably have imagined that morning.
Three British armoured cruisers were gone.
U-9 turned eastward for Germany and slipped away beneath the North Sea, unseen and unpunished. Behind her, the survivors were left to the water.
The explosions had carried far.
A Dutch merchant steamer well beyond the patrol area had seen the smoke rising above the horizon and altered course toward it. Two Dutch fishing vessels did the same. As they drew closer, the scale of the disaster became visible: first smoke, then wreckage, and finally hundreds of tiny figures scattered across the sea.
The Dutch came as quickly as their engines allowed.
Boats went down. Ropes and ladders were thrown over the sides. Fishermen hauled half-conscious British sailors from the water by their collars and belts, sometimes having to pry frozen hands from pieces of wreckage before the men could be dragged aboard.
British ships were coming as well. Distress signals and reports of the explosions were already pulling destroyers and cruisers toward the Broad Fourteens.
For most of the dead, they would arrive too late.
The destruction was far worse than anything the Royal Navy had imagined one submarine capable of inflicting. Aboukir had at least remained afloat long enough for some of her crew to escape. Hogue and Cressy, struck at close range by the newer German torpedoes and torn apart by secondary explosions, had given many of their men only seconds.
When the casualty lists were eventually reconciled, scarcely more than a few hundred men had survived.
Nearly two thousand were dead or missing.
Drummond, pulled half-conscious from the water after spending much of the disaster trying to keep other sailors afloat, would become one of the few senior officers to survive. Nicholson and Johnson were gone, together with most of the officers who had stood upon their bridges.
The Royal Navy had lost three armoured cruisers in less than an hour to a single submarine.
Germany would make certain the world heard about it.
Within days, Weddigen's name would appear across the Reich beneath enormous headlines. U-9 would become a symbol of the new German Navy: small beside the battleships of the world, almost invisible until the moment it struck, yet capable of destroying ships many times its size. When Weddigen returned home, the Kaiser himself would eventually honour him with the Iron Cross, while decorations and commendations spread throughout his crew.
Germany would celebrate, while Chatham and the Medway would mourn.
The casualty lists would fall heavily upon communities from which so many of the reservists had been called. Streets would lose several men at once. Brothers would disappear together. Wives would become widows, and children who had watched their fathers leave only days before would soon see telegram boys approaching their doors.
The Admiralty would count ships, patrol routes and tonnage.
The people waiting at home would count names. Yet even that grief belonged to the hours and days still to come.
For on the morning of 20 July, while British destroyers and rescue vessels were already turning east toward the smoke rising above the Broad Fourteens, the danger to Britain had not yet passed.
While wireless stations filled with confused reports of Aboukir, Hogue and Cressy disappearing off the Dutch coast, the other German submarines were already farther southwest, slipping quietly into the English Channel.
They were hunting the British Army.
The movement of the British Expeditionary Force had begun almost as soon as Britain entered the war. Roughly seventy-five thousand professional soldiers had to be carried across the Channel, and with them came everything required to turn those men into an army once they reached France: horses, artillery, ammunition, machine guns, wagons, medical stores, food and thousands upon thousands of tons of supplies. The Royal Navy did not possess a dedicated transport fleet large enough to move all of it on its own, so Britain had done what maritime powers had always done in wartime and requisitioned civilian shipping in enormous numbers.
Merchant steamers, passenger vessels, ferries and cargo ships were gathered until nearly two hundred and fifty vessels had been drawn into the movement. Along Britain's southern coast, trains arrived almost continuously while columns of soldiers marched aboard beneath shouted orders. Horses were coaxed or dragged up ramps, artillery disappeared into holds, ammunition crates were stacked wherever space could be found and exhausted dockworkers laboured through day and night to keep the movement flowing. Ships crossed toward Boulogne, Le Havre and other French ports, unloaded, turned around and came back for another load. By 20 July, the Channel had become less a body of water than a great maritime road carrying Britain's war effort into Europe.
The transports did not travel alone. British cruisers and destroyers watched the principal routes, French warships guarded their own approaches and aircraft occasionally circled overhead, their crews staring down at the crowded lanes below. To the soldiers packed aboard the transports, the sheer number of friendly ships around them could appear reassuring. Britain ruled the sea, and they were crossing one of the most heavily watched stretches of water in the world.
Then reports began arriving from the east.
Smoke was already rising somewhere beyond the Channel approaches where the three British armoured cruisers had disappeared. Wireless messages came in broken and contradictory: submarine attack, cruisers sinking, hundreds of men in the water. Patrol vessels began turning toward the Broad Fourteens while officers ashore tried to understand how one enemy submarine could possibly have inflicted such destruction.
And while British attention was being pulled eastward, the rest of U-9's wolfpack struck farther west.
There was almost no warning. A lookout aboard one transport noticed a pale line moving through the water and pointed toward it. Another sailor shouted, a bell began ringing somewhere aboard the convoy, and then the first torpedo struck. The explosion tore into the transport below the waterline, sending smoke, water and fragments of steel high above her deck. Before the ships around her had even understood what had happened, a second transport was hit, followed moments later by another.
The orderly procession across the Channel collapsed into confusion. Captains hauled their ships out of line, engine-room telegraphs clanged and transports began turning away from one another while escorts raced between them searching desperately for periscopes. Soldiers who had expected their first battle to take place somewhere in Belgium or France suddenly found themselves staring over the rail at the sea, wondering whether the next white wake would be coming toward them.
One British destroyer charged across the convoy's flank after a lookout reported movement beneath the surface. She had barely begun her run when a torpedo caught her almost head-on. The explosion swallowed the little warship in spray and flame, breaking the hull apart so violently that men aboard the nearby transports saw pieces of her thrown clear before the wreckage disappeared beneath the water. What remained of her crew was scattered among the same waves they had been trying to protect.
The wolfpack continued its attack from different directions, firing at intervals irregular enough to make the British believe even more submarines might be present than actually were. Escorts fired at suspicious wakes, floating wreckage and shadows beneath the surface. Shells and machine-gun bullets tore into patches of water that moments later appeared entirely empty. The Germans rarely gave them anything more substantial to aim at. They struck, changed position beneath the confusion and disappeared again before the surface ships could properly close upon them.
By the time the attack finally ended, nine transports had been hit. Six went down outright, some rapidly enough that men below decks never reached the open air, while three others survived only badly crippled and were eventually taken under tow. The Channel filled with lifeboats, wreckage and soldiers struggling in the water. Horses trapped below decks screamed as the stricken ships listed and rolled around them, while artillery, ammunition, wagons, rifles, tents and medical stores disappeared beneath the sea along with the men who had been assigned to use them.
Thousands were pulled from the water, but hundreds were not.
For hours afterward, British and French warships searched the Channel. Destroyers raced back and forth across the attack lanes while lookouts stared until their eyes burned, waiting for the brief rise of a periscope or the low silhouette of a submarine forced to the surface. Every unusual ripple drew attention; every reported wake sent guns swinging toward the water. Yet nothing useful was found. The wolfpack had struck quickly and withdrawn before the British could close around it, some boats continuing westward beneath the traffic lanes before turning away once their torpedoes had been expended.
By the time the Royal Navy properly understood the scale of what had happened, the attackers were already disappearing.
Thus 20 July became the first truly black day of Britain's naval war. Until then, the losses had been painful but distant enough to remain manageable. Merchantmen had gone missing in the Atlantic. Cargoes had been lost. German battlecruisers were somewhere beyond Scotland, and submarines were appearing in waters where British planners had never expected them so early. It was alarming, certainly, but still something that could be discussed in terms of commerce, insurance and patrol routes.
The twentieth was different.
Three British armoured cruisers had been destroyed in the Broad Fourteens by a single submarine. Farther west, the wolfpack had struck the transports carrying the British Army across the Channel, sinking ships, killing soldiers and sailors and sending military equipment meant for France to the bottom. A destroyer had been blown apart while trying to defend the crossing. For the first time since Britain entered the war, Germany had not merely attacked British trade. It had struck directly at the machinery carrying Britain's army onto the Continent.
Throughout the afternoon and evening, reports began converging upon London. At first they contradicted one another so badly that officers struggled to separate fact from panic. Three cruisers missing became three cruisers sunk. A suspected mine became confirmation of a submarine attack. Reports of several damaged transports became six sunk and three crippled. A destroyer disappeared from the lists. Casualty estimates climbed with every new telegram, while frantic messages from the Channel spoke of survivors, lost equipment and additional submarines that no one could locate.
Each report arriving at Whitehall seemed worse than the last.
Only a day earlier, Churchill had been worrying about merchantmen lost to German raiders in the Atlantic and reassuring the Prime Minister that the Royal Navy possessed both the strength and the plan to restore order. Those losses now seemed almost modest beside what had happened on 20 July.
By nightfall, clerks were gathering the newest telegrams into bundles and carrying them through the Admiralty toward the offices where Winston Churchill would soon read them.
The first great naval bloodletting of Britain's war had begun, and the sea had already taken a terrible price.
