Waterloo (1970) Timeline Explained – Every Event in Order

Napoleon escaped from Elba in 1815 because he refused to accept his defeat and exile after the 1814 campaign. Despite being forced to abdicate by his own marshals, he spent about a year on the island planning his return. His escape was a bold gamble, he sailed back to France with a small guard and quickly rallied supporters, shocking Europe and reclaiming power before the Allied forces could respond.

Wellington chose to stand at Waterloo after learning Napoleon was marching into Belgium, which threatened to split the Allied forces. At the Duchess of Richmond's ball in Brussels, he received news of the French advance and realized he needed to make a stand at a defensible position. Waterloo offered a strong ridgeline and access to roads that would allow the British to retreat if necessary while waiting for Prussian support.

Napoleon ordered Grouchy to lead 30,000 troops to prevent the Prussians from rejoining Wellington's army. Grouchy's failure to effectively pursue the Prussians allowed Blücher's forces to regroup and march toward Waterloo. This was crucial because Napoleon had split his army, weakening his main force at Waterloo in hopes of keeping the Allies separated, a gamble that backfired when the Prussians arrived to reinforce Wellington.

Foreshadowing: Napoleon ordered Grouchy to pursue the Prussians after his victory at Ligny.

Ney led a bold cavalry assault against the British lines, but the infantry formed defensive squares that withstood the charge. The British squares were disciplined formations that presented a wall of bayonets to the cavalry, inflicting heavy losses on the French. Additionally, a misinterpreted order, telling Allied troops to retire 100 paces, was taken as a full withdrawal, prompting Ney to press the attack, but the British center held firm.

The Imperial Guard broke because Napoleon committed them too late in the battle and they were caught by a devastating volley from Maitland's 1st Foot Guards at close range. The Guard had been held in reserve for a decisive blow, but when they finally advanced, they walked into concentrated fire from rested British guardsmen. The combination of this unexpected defense and the timely arrival of Prussian forces caused the Guard, historically unbroken, to collapse for the first time.

Foreshadowing: Napoleon commits the Imperial Guard to deliver the decisive blow.

The Prussians arrived in the evening of June 18, 1815, during the final phase of the battle. After being defeated by Napoleon at Ligny, Blücher's forces retreated but regrouped and marched toward Waterloo despite Wellington's uncertainty about their arrival. Their timely arrival tipped the balance decisively in favor of the Allies, completing the encirclement that forced the Imperial Guard's retreat and subsequent breakdown.

Foreshadowing: Wellington suspects Grouchy's advance while Blücher presses toward the field.

General Picton was killed while attempting to plug a gap in the British line when a Dutch brigade faltered, he died leading troops to hold the center. Colonel Ponsonby was cut down during a daring cavalry charge toward French guns; he became isolated from the main Allied force and was surrounded and killed by French lancers. Both deaths exemplified the brutal cost of the battle, where even senior commanders were vulnerable on the front lines.

Napoleon withdrew briefly during the battle due to a severe stomach illness that left him incapacitated. He delegated command to Marshal Ney during his absence. This was a critical moment because without Napoleon's direct command, the French forces lost coordination at a pivotal time, and Ney made the bold cavalry charge that ultimately failed when the British squares held their ground.

When Ney traveled to report to Napoleon after the battle at Quatre-Bras, his timing inadvertently allowed Wellington to withdraw his lines intact. Had Ney remained in pursuit or coordinated differently with Napoleon, Wellington might not have been able to retreat cleanly to Waterloo. This moment showed how the decisions of individual commanders shaped the larger strategic picture.

The most decisive moment was when Maitland's 1st Foot Guards delivered a devastating close-range volley that shattered the Imperial Guard's assault. This was followed immediately by the arrival of Prussian forces. For the first time in its history, the Imperial Guard, a force that had never been broken, retreated in disorder. This double blow broke French morale and sealed the Allied victory.
