17th Lithuanian Uhlan Regiment
The 17th Lithuanian Uhlan Regiment was an uhlan regiment of the Grande Armée during the Napoleonic Wars.
1812
Formation
Due to a lack of funds, Napoleon appealed to the Lithuanian nobility, especially the aristocracy, urging them to raise troops at their own expense. Michał Tyszkiewicz donated 76,137 złotys and 7.5 groszes, one-sixth of the uniform costs, and was therefore appointed commander of the regiment. Tyszkiewicz, however, was an experienced soldier, having previously served as a rotmistrz in the 2nd Lithuanian National Cavalry Brigade and as a captain in a Russian Hussar Regiment. On 5 July 1812, Tyszkiewicz began forming the Uhlan regiment. On August 12, he received an order from the head of the Military Commission, Prince Aleksander Sapieha, to begin recruiting soldiers.The men who joined the regiment came from the towns of Biržai, Raseiniai, Telšiai, Panevėžys and their respective surroundings. The regimental headquarters were in Kupiškis. Napoleon appointed Count Michał Tyszkiewicz as the regiment's commander and awarded him the rank of colonel. The regiment, like other Lithuanian regiments, retained the numbering continuity of the cavalry regiments of the Duchy of Warsaw.

At the end of 1812, together with other Lithuanian units, this regiment covered the Grande Armée's retreat and joined the X Corps. In December 1812, the 17th Uhlan Regiment retreated through Tauragė to Königsberg.War of the Sixth Coalition

On February 4, it fought near Brandenburg.On February 11 or 12, the 17th Uhlan Regiment fought together with the 19th Lithuanian Uhlan Regiment near Sieraków. There it was surprised and defeated by General Chernyshev's Russian vanguard. The general Prince Romuald Giedroyć, who commanded both Uhlan regiments, was taken prisoner. He was wounded during his capture. During the battle, the regiment lost 147 out of 585 men it had before.

On 20 April 1813, men from the 19th Regiment were drafted into the regiment, after 225 soldiers from the 19th Regiment were selected for the Imperial Guard. The 19th Regiment's former commander, Col. Konstanty Rajecki, became the new commander of the 17th Regiment.
