HISTORY.
(21st Corps District—Lorraine.)
1914.
Lorraine.
1. Upon mobilization, the 42d Division and the 31st Division formed the 21st Army Corps.
It was a part of the 6th Army (Prince Rupprecht of Bavaria), and fought, at the beginning of August, 1914, across the Lorraine frontier, in the vicinity of Château Salins, Dieuze, Rechicourt (Aug. 5–12). Engaged on the 20th northeast of Dieuze, the 42d Division reached Lunéville on the 22d and attacked Rehainviller and Gerbeviller on the 24th. These days had been very costly. On August 26 the 121st Infantry Regiment was reduced to 31 officers and 1,562 men. (Official Document.)
2. At the beginning of September it was sent to reenforce the 2d Bavarian Corps. On September 3 it was in the vicinity of Moyen-Domptail. It retired to Dieuze (Sept. 11–13) and entrained at Boulay on the 18th, for Cambrai.
Somme.
3. On September 24 it was on the Somme. It fought at Gruny, Maucourt, in the vicinity of Chaulnes-Pressoire (end of September to beginning of October). It took up its position on the Chaulnes front, along the road from Amiens to St. Quentin (November-December).
