The exact order of battle of French forces is not clear, but contemporary sources suggest the presence of a portion of General Claude Lecourbe's Corps of 28,368, including the forces of generals Laval, Molitor, Jardon, and Vandamme.  This is also confirmed in an extract of Moreau's dispatch to the French Minister of War, published in the London Chronicle, 10 June 1800.  "The 6th Chasseurs, 13th Cavalry, 4th Hussars and 11th Chasseurs distinguished themselves in this affair.  The rest of the division, and that of , passed rapidly  the Danube...General Grenier was equally well prepared." In addition, the presence  of Théophile Corret de la Tour d'Auvergne, the First Grenadier of France, suggests that the grenadier company of the 46th Demi-brigade infantry de ligne was at least engaged.  In addition, General Espagne's 37th and 84th Regiments were engaged, as were grenadiers the 109th Regiment.  Lecourbe mentions the 37th and the 109th several times in his own account of the battle, so apparently they were heavily engaged: this would include the brigades of François Goullus and François Bontemps.
