In 1812, Bagration commanded the 2nd Army of the West. A few days before Napoleon's invasion on 24 June, he suggested to Alexander I a pre-emptive strike into the Duchy of Warsaw. Defeated at Mogilev (23 July), Bagration led his forces to join the 1st Army at Smolensk under Barclay de Tolly, to whom he ceded overall command of both armies on 2 August. Bagration led the left wing at the Battle of Borodino (7 September) where he constructed many flèches which, due to a shortage of engineer officers, were poorly built. During the battle, he received a mortal wound and later died from gangrene on 24 September, in the village of Simi, where his aunt resided.
