During the interbellum period, the division was stationed in the city of Wilno, which in 1922 - 1939 was part of the Second Polish Republic. Until 1927, it was commanded by General Michal Tokarzewski-Karaszewicz, who was replaced by General Tadeusz Kasprzycki (1927 - 1931). For most of the 1930s, the division was commanded by General Eugeniusz Godziejewski, who in mid-April 1936 was replaced by its last interbellum commandant, General Jozef Kwaciszewski. The 19th I.D. fought in the September 1939 German Invasion of Poland, as part of the Prusy Army. Later it was recreated as a Home Army unit, taking part in the Operation Ostra Brama in the summer of 1944.

The 19th I.D. under General Jozef Kwaciszewski belonged to northern group of Prusy Army, under General Stefan Dab-Biernacki. On September 5, 1939, the division was sent to the area of Piotrkow Trybunalski, where it faced the 1st Panzer Division of the Wehrmacht. Under German pressure, it had to withdraw on Sept. 6, and on the same day, the Germans captured General Kwaciszewski. On Sept. 7 in the evening, units of the division scattered, trying to break through German lines and escape eastwards, towards the Vistula.

Following the order of General Dab-Biernacki, its name was changed to the 19th Infantry Brigade. The unit took part in the Battle of Tomaszow Lubelski, capitulating on September 27th.

Reserve center of the division was stationed in Lida. On September 17, 1939, when news of the Soviet Invasion of Poland reached the town, an assault company of 150 men was formed in Lida, with the task of breaking through the advancing Red Army, and reaching Wilno. The plan was changed, and the company headed for Grodno, where it took place in the Battle of Grodno.
