On the morning of the 18th at the Battle of Waterloo, Napoleon placed the VI Corps in the second line, with the divisions of Generals Simmer and Jeanin one behind the other just to the west of the Charleroi to Brussels highway. When the approach of the Prussian Army was detected, Lobau's two divisions were moved to the east flank, behind the division of General Durutte and facing east. At about 4:00 PM, General von Bülow gave the order to attack and Lobau found himself outnumbered three-to-one by the Prussians. He quickly shifted his position to occupy Plancenoit with his right flank brigade while the rest of his infantry and the light cavalry divisions of Generals Subervie and Domon covered the left flank. This was the start of a brutal fight for the village. When the Prussians began to overrun the village, the 4,200-strong Young Guard arrived and drove them out. As the reinforced Prussians again began to press forward, 1,100 soldiers of the Old Guard attacked and recaptured Plancenoit. This triumph helped Lobau's troops hold the line north of the village. Eventually, the Prussians cleared the village in vicious no-quarter fighting that went on into the evening. Unaware that Napoleon's army was routed at Waterloo, Teste's detached division attacked and captured the hamlet of Bierges on the morning of the 19th during the Battle of Wavre. This local success forced the Prussian III Corps to retreat.
