During the Napoleon's invasion of Russia in 1812, Tyszkiewicz supported Napoleon in hopes of reestablishing the old Grand Duchy of Lithuania. On July 5, 1812, using his own funds, he began forming the 17th Lithuanian Uhlan Regiment, with his own initiative and money.[2] In recognition, Napoleon named Tyszkiewicz the regimental commander with the rank of colonel and Chevalier of the Legion of Honour.[3] The regiment was attached to the X Corps of the Grande Armée. Tyszkiewicz became ill and did not participate in action; the command was taken over by major Kozlovsky.[4] In 1904, his great-grandson published Histoire du 17me Régt de cavalerie Polonaise Lanciers du Cte Michel Tyszkiewicz 1812-1815 about the regiment.
Estates
Tyszkiewicz made several large acquisitions of manors to become a large landowner. In 1811, after lengthy legal proceedings, he acquired the ruined Biržai Castle and dependent serfs from Dominik Hieronim Radziwiłł for 450,000 silver rubles.[3] In 1819, Tyszkiewicz bought Raudondvaris Castle. It was gifted to his son Benedykt Emanuel Tyszkiewicz on the occasion of his wedding to Vanda Vankovich, daughter of Anton Vankovich [be].[5] On July 13, 1824, Tyszkiewicz bought Palanga with manors in Darbėnai, Grūšlaukė and Palanga from General Franciszek Ksawery Niesiołowski for 177,171 silver rubles.[6] Palanga was developed as a seaside resort by his grandson Feliks Tyszkiewicz (1870–1932) who also built the current Tiškevičiai Palace. On April 23, 1828, Tyszkiewicz bought Nemėžis Manor and built the two-storey manor house that survives to this day.[7]
