Colbert was promoted to général de brigade on 9 March 1809 and put under the orders of Oudinot. He won glory at the Battle of Raab by charging and defeating Ott's hussars, cutting several squadrons of the enemy Hungarian cavalry to pieces and nearly coming to the aid of the 9th Hussar Regiment, which the Austrians were on the point of overwhelming. At Wagram Colbert was shot in the head three times and was made a commander of the Légion d'honneur.
