After the collapse of
Austria-Hungary on 28 October 1918, the
Polish Liquidation Committee was formed in
Kraków to organize Polish military and administrative structures in
Galicia. On 1 November 1918, the Governing Council and Garrison Command were created in
Przemyśl to begin organizing Polish military forces and administration. In the barracks of the former Austro-Hungarian 45th Infantry Regiment, scattered military units were gathered, forming the foundation for the 37th Infantry Regiment. By 7 November 1918, an infantry regiment was established in Przemyśl, which was renamed the 18th Rifle Regiment on November 9. The battalion commanders at that time were: 1st Battalion – Second Lieutenant Zając, 2nd Battalion – Second Lieutenant Dudziński, 3rd Battalion – Marian Doskowski. The regiment gained its first combat experience during clashes with Ukrainian forces from 9 to 11 November 1918 in the Zasań district of Przemyśl. On November 13, the regiment was renamed the 10th Infantry Regiment. In November 1918, the regiment's reserve battalion, formerly part of the Austro-Hungarian , was commanded by Captain , who was appointed as the temporary commander of the "Children of Przemyśl" 10th Infantry Regiment. On 30 November, Lieutenant Kazubski was replaced by Lieutenant Colonel as the commander of the regiment. Part of the regiment fought to open the road to the besieged
Lviv as part of Colonel
Michał Tokarzewski-Karaszewicz's group, while the rest engaged in combat near
Nyzhankovychi,
Siedliska,
Medyka, and
Khyriv. The regiment captured Stodółki,
Uhry, Czerlany, and
Velykyi Liubin. It also held
Horodok and defended the Lviv-Przemyśl railway line from Ukrainian forces. On 25 February 1919, the regiment was renamed the 37th Infantry Regiment. In the spring of 1919, the regiment captured
Sambir and
Drohobych and participated in the conquest of
Stanyslaviv. From 13 to 16 June 1919, it defended crossings over the
Dniester river. From June 28, the regiment fought along the
Zbruch river, and in July 1919, it was transferred to the Volhynian front, where it battled Ukrainian units. From August 5, the regiment took on a defensive role. On 3 April 1920, Major Józef Kuś became the commander of the 37th Infantry Regiment. In December 1919, the regiment's reserve battalion was stationed in
Łęczyca.
