17th June 1815: Storm and Strategy

In this pivotal episode, we explore the pivotal episode that is the often-overlooked day between the battles of Ligny and Waterloo—17 June 1815—a day of dramatic retreats, strategic decisions, and torrential rain.

After their narrow escape from Napoleon’s forces at Quatre Bras, Wellington’s Anglo-Allied army began a calculated retreat north to a defensive ridge near the village of Waterloo. As storms broke over Belgium, Wellington’s rearguard skirmished with French cavalry, buying precious time while soldiers trudged through deepening mud. Despite the chaos, the Duke maintained discipline and prepared for what he hoped would be a decisive stand.

Meanwhile, the Prussian army, reeling from defeat at Ligny, faced a critical crossroads. Instead of falling back east toward safety, Blücher and his chief of staff Gneisenau made a bold choice: to retreat north to Wavre, keeping their promise to support Wellington. Despite battered ranks, exhaustion, and worsening weather, the Prussians rallied and moved into position to rejoin the fight.

Napoleon, hindered by rain and uncertain about the Prussians' next move, delayed his pursuit. He sent Marshal Grouchy to chase the Prussians—but Grouchy's march would be too slow, and too late (or were they just sent despatched too late to do the task they were assigned?).

The stage was now set: two allied armies regrouping under impossible conditions, united by determination and strategy. The storm would pass—but the storm of battle was only a day away.
