Seventh Army (France)
The Seventh Army (French: VIIe Armée) was a Field army of the French Army during World War I and World War II.
It was created on 4 April 1915 to defend the front between the Swiss border and Lorraine, as successor of the independent Army Detachment of the Vosges under General Putz. This Detachment had been created on 8 December 1914, with the stabilisation of the Western Front as successor of the Army of Alsace, Groupement des Vosges and 34th Army Corps.
The Seventh Army held the same position until the end of the War. Its major involvements were the Battle of Hartmannswillerkopf and the Battle of Le Linge in 1915.
