Eugène took MG Grouchy from his corps command and reassigned him to command the 5,371 troopers in the cavalry divisions of MG Montbrun, BG Guèrin, and BG Colbert. These were posted on the right (south) flank with the intention of turning John's left flank. Eugène ordered Grenier to assault the Austrian center with the 15,662 men of his two divisions. MG d'Hilliers was instructed to attack the Austrian right with his single division of 8,315 soldiers. Eugène held the troops from Grouchy's corps in reserve, MG Pacthod's 5,166-foot soldiers and MG Sahuc's 1,280 cavalry. He also kept back MG Pully's 1,470 dragoons and MG Lechi's 2,438 Italian Guards.
