Polish I Corps (1917–1918)

The Third Uhlan Regiment was formed in November 1917, as part of the Polish I Corps in Russia. It existed only until July 1918, and consisted of elements of several other ethnic Polish units.

Third Army (1918–1921)

On 13 October 1918, in Warsaw, Colonel Stefan Strzemieński began forming a new Uhlan regiment. Its squadrons were located both in Warsaw and Zagłębie Dąbrowskie, taking part in disarming demoralized German soldiers of the Ober Ost. In January 1919, two squadrons were sent to the eastern region of former Austrian Galicia, to fight in the Polish–Ukrainian War. In April 1919, the whole regiment fought in Polesie and around Minsk, remaining in Belarus until May 1920.

As part of Edward Rydz-Śmigły's Third Army, the regiment fought in the 1920 Kiev offensive. It protected the Polish rear during the retreat of early summer 1920 and then fought against the Soviets in the bloody Battle of Cycow. In this battle, together with 7th Lublin Uhlan Regiment, it formed the 4th Cavalry Brigade. After the battle, the regiment chased the enemy towards Białystok and Augustów, where it clashed with Lithuanian troops, advancing southwards. It then fought in the Battle of the Niemen River, remaining along Polish–Soviet demarcation line until mid-1921.

Historical banner of the 3rd Regiment

On 16 October 1921, a flag was presented to the regiment, and it was named Third Children of Warsaw Uhlan Regiment by the City Council of Warsaw. This name was not officially accepted by the Ministry of Military Affairs.

In June 1922, the regiment was sent to the Polish part of Upper Silesia, to take over the part of the region that was awarded to the Second Polish Republic after the Upper Silesia plebiscite. In the same year, it was garrisoned in the town of Tarnowskie Góry, where it remained until the 1939 Invasion of Poland. In 1924, its reserve squadron was placed in Bochnia, and in 1926, the third squadron was garrisoned in Pszczyna. From 1937–1939, the regiment was a part of the Kraków Cavalry Brigade. The adjective "Silesian" was added to its official name in 1938, following a motion of the Silesian Sejm.
