The regiment dated back to November 1917, when Polish Cavalry Squadron was formed out of ethnic Poles, serving in
Imperial Russian Army's 9th Cavalry Division. In January 1918, the squadron was reorganized into a regiment, which soon afterwards joined the
Polish II Corps in Russia. On May 12, 1918, after the
Battle of Kaniów, the regiment was dissolved by the Germans, who sent its officers to
Brest Fortress. On November 13, 1918, officers of the regiment were released from German prison, and arrived at
Warsaw. On the next day, they began forming the 5th Uhlan Regiment, which was at first based in
Mińsk Mazowiecki. The regiment fought in the
Polish–Soviet War, after which it was garrisoned in Ostrołęka. During the 1939
Invasion of Poland, it belonged to
Podlaska Cavalry Brigade. In the summer 1944, the regiment was recreated by the
Home Army, to fight in
Operation Tempest. == Commandants ==
