5th Regiment of Zaslaw Uhlans

5th Regiment of Zaslaw Uhlans (Polish language: 5 Pulk Ulanow Zaslawskich, 5 p.ul.) was a cavalry unit of the Polish Army in the Second Polish Republic. It was garrisoned in the city of Ostroleka, while its reserve was based in Garwolin. The regiment celebrated its day on September 26, the anniversary of the 1920 Charge of Zaslaw. Its traditions were based on the 5th Uhlan Regiment, created in 1830, which fought in the November Uprising.

History
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 Kaniow, 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 Minsk Mazowiecki. The regiment fought in the Polish-Soviet War, after which it was garrisoned in Ostroleka. 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.
