Battle of Waterloo
His first battle was at Ligny, and after a fierce day of fighting, he defeated the Prussian army, forcing it to retreat. Thinking that Blücher would retreat back to Prussia, Napoleon turned his attention towards Wellington. There was already a small battle at Quatre Bras, as Wellington tried to delay the French advance. That gave Wellington enough time to prepare a full defensive position across the road leading to Brussels near the village of Waterloo.
