After the battle of Sedan on September 1, 1870 and the collapse of the Second Empire, followed by the investment of Paris, the Government of National Defense set about raising fresh armies. These had as their first objective the relief of the capital. The German troops covering the investment were stretched extremely thin until the fall of Metz at the end of October 1870. This released the forces around the city to move north and west to deal with the newly forming French armies.
The German Campaign in the northeast of France was conducted by the First Army led by General Edwin von Manteuffel. Opposing him was the French Army of the North, initially commanded for a short time by General Charles Bourbaki. He was soon replaced by General Louis Faidherbe, who was sent far from Africa.
