 General Pershing's headquarters. The accessories consist of the

 Forces. This includes helmets of different types, one camouflaged

 masks for men and horses ; a gas-proof cage for carrier pigeons, with

 by the Fifth American Division during the Argonne-Meuse offen-

 captured in the Argonne Forest ; an anti-tank gun, a water-cooled 

 machine gim, a field operating chair, trench tools, grenades and
