In Napoleon's view, capturing La Haye Sainte was tantamount to severing Wellington's jugular vein, so he dispatched his most elite Imperial Guard to advance on La Haye Sainte.
At the same time, Sir Adam Henry also received orders from the Duke of Wellington to strike the enemy on the flank.
The Adam's Brigade, which had been on standby since the beginning of the battle, quickly unfolded upon receiving the order. At that time, the 52nd Regiment advanced in a diagonal formation and executed a highly precise volley, flanking the advancing French Imperial Guard, thereby causing the Imperial Guard's first public retreat.
