Back in France, after some leave, Morand was made commandant of the Department of Morbihan on 19 March 1802 before being called to Marshal Soult's camp at Saint-Omer on 30 October 1803. He was made an Officer of the Legion of Honour on 11 December 1803, and a Commander on 14 June 1804. When the Grande Armée marched for Austria in August 1805, he commanded the first brigade in Saint-Hilaire's first division of Soult's IV Corps. He was present at the battle of Donauwörth and the remainder of the Ulm campaign, culminating in the capitulation of General Mack.
