When Adolf Hitler became chancellor in 1933, he instructed the Truppenamt/General Staff to ignore the Versailles restrictions, he would create a greatly expanded Wehrmacht from the army, navy, and air-force. A new War Academy ("Kriegsakademie") was established in 1935. The General Staff advised Hitler that the German Army could not be fully modernized until 1944 or 1945. When Hitler went to war in 1939 the tank columns were still followed by horse-drawn artillery pieces. Throughout the war German industry was unable to furnish small arms in sufficient quantities, forcing the Army to rely heavily on older weapons, prizes of war, and adaptations of former designs produced in conquered countries, thus producing an arsenal filled with an array of incompatible pieces, unlike the smaller number of standard small arms used by the Allies.
