Just two days later, another Allies battleship was sunk.
This time, it was the British ship "Dignity".
Its defense was more tightly secured, besides the anti-torpedo net, there were also merchant and transport ships encircling it, along with three destroyers and two trawlers patrolling around.
Yet, the Germans submarine still successfully sunk it.
The Germans were smart; they chose to attack at dawn when the slightly brightening sky cast darkness over the water, making it impossible for sailors to spot the periscope, while the submarine could accurately judge the battleship's position by its massive shadow.
Thus, the German submarine launched a torpedo from 500 meters away, traversing the calm water miraculously through the gap between two defending merchant ships, breaking through the anti-torpedo net and accurately hitting the center of "Dignity".
Due to the explosion being right in the center, "Dignity" sank within seven minutes.
