The 121st Division was formed in the Falkenhausen Army in Lorraine in April, 1915. Its three regiments came from divisions which had been in existence for some time. The 60th came from the 31st Division (21st Corps), the 7th Reserve from the 9th Reserve Division (5th Reserve Corps), and the 56th Reserve from the 13th Reserve Division (7th Reserve Corps). These regiments were brought together in the region of St. Avold-Faulquemont at the beginning of April and on the 9th reached Thiaucourt, Euvezin, and the Mort Mare wood (notebooks).
