First engagement of Infanterie Regiment 9 in Poland - September 1939.
The Infanterie Regiment 9 was created in 1920 as part of the New Reichsheer forces, maintaining the traditions of the old Prussian Guard. In August 1921 the units newly organized units took the traditions of the dissolved units and the 1. Company of the I. / IR 9 took the tradition of the 1. Preußischen Garderegiments zu Fuss (1 st Regiment of the Prussian Guard on foot). The command of the regiment along with its I. and II. Battalions were based in Potsdam and its III. Battalion in Spandau.
On October 1, 1934, the former commander of the IR 9 (Prussia), Generalmajor Busch, was appointed commander of the newly formed 23 ID. Together with the IR 9 (Prussia) formed the division: IR 67 (Spandau), IR 68 (Brandenburg), AR 23 (Potsdam), NA 23 (Potsdam) and other Divisional units. As a symbol of the division, which now decorated all vehicles in the unit, was elected a stylized Grenadier of the Guard of Frederick William I.
