The Battle of Brienne saw an Imperial French army led by Emperor Napoleon attack Prussian and Russian forces commanded by Prussian Field Marshal Gebhard Leberecht von Blücher. After heavy fighting that went on into the night, the French seized a château, nearly capturing Blücher. However, the French were unable to dislodge the Russians from the town of Brienne-le-Château. Napoleon himself, making his first appearance on a battlefield in 1814, was also nearly captured. Very early the next morning, Blücher's troops quietly abandoned the town and retreated to the south, conceding the field to the French.

Gebhard Leberecht von Blücher, Fürst von Wahlstatt, Graf (count), later elevated to Fürst von Wahlstatt, was a Prussian Generalfeldmarschall. He earned his greatest recognition after leading his army against Napoleon I at the Battle of the Nations at Leipzig in 1813 and the Battle of Waterloo in 1815.
