In 1805 Russia joined the coalition against Napoleon. After the collapse of the Austrians at Ulm in October 1805, Bagration won praise for his successful defense in the Battle of Schöngrabern (November 1805) that allowed Russian forces to withdraw and unite with the main Russian army of Mikhail Kutuzov. In December 1805 the combined Russo-Austrian army suffered defeat at the Battle of Austerlitz, where Bagration commanded the allied right wing against the French under Jean Lannes. Later he commanded Russian troops in the Finnish War (1808-1809) against Sweden and in another war against the Turks (1806–1812) on the Danube.
