The battle of Champaubert was one of the few times during the War of the Sixth Coalition that France was able to take to the field with a considerable numerical advantage. Napoleon Bonaparte moved against an over-extended Prussian army in the hope of whittling it down by a series of battles. On 10 February, he caught General Olssufiev's five thousand Russians just south of Champaubert, a town located in the valley of the Marne, east of Paris. The French lost about three hundred men, among whom was General Joseph Lagrange, wounded.
