The Battle of Waterloo, a pivotal conflict between Napoleon and Wellington, took place on a four-mile-wide battlefield with key strong points at Hougoumont Chateau, La Haye Sainte farmhouse, and the Farm of Papelotte. Wellington commanded 68,000 men and 156 guns, facing Napoleon's 72,000 and 246. Napoleon, grappling with morning issues, including illness, uphill attacks, and waterlogged ground, delayed his assault until 11 o'clock. The French initially targeted Hougoumont, and while heavy artillery fire caused some Dutch and Belgian units to break, the battle remained in the balance.
