The Battle of Reims (12–13 March 1814) was fought at Reims, France between an Imperial French army commanded by Emperor Napoleon and a combined Russian-Prussian corps led by General Emmanuel de Saint-Priest. On the first day, Saint-Priest's Russians and General Friedrich Wilhelm von Jagow's Prussians easily captured Reims from its French National Guard garrison, capturing or killing more than half of its defenders; this event is also mentioned as the storming of Reims. On the second day, an overconfident Saint-Priest carelessly deployed his forces west of the city, not grasping that Napoleon was approaching with 20,000 troops. Too late, Saint-Priest realized who he was fighting and tried to organize a retreat. In the battle that followed, the French army struck with crushing force and the Allies were routed with serious losses. During the fighting, Saint-Priest was struck by a howitzer shell and died two weeks later.
