two infantry divisions under Generals of Division Louis Gabriel Suchet and Honoré Théodore Maxime Gazan de la Peyrière. Suchet's 1st Division included General of Brigade Michel Marie Claparède's 3-battalion 17th Light Infantry Regiment, General of Brigade Honoré Charles Reille's 4-battalion 34th Line Infantry Regiment and 3-battalion 40th Line Infantry Regiment, and General of Brigade Dominique Honoré Antoine Vedel's 64th and 88th Line Infantry Regiments, three battalions each. Gazan's 2nd Division comprised General of Brigade Jean François Graindorge's 3-battalion 21st Light Infantry Regiment and 2-battalion 28th Light Infantry Regiment and General of Brigade François Frédéric Campana's 100th and 103rd Line Infantry Regiments, three battalions each. General of Brigade Anne-François-Charles Trelliard led 12 squadrons of the corps cavalry, which consisted of the 9th and 10th Hussar Regiments and the 21st Chasseurs à Cheval Regiment. General of Brigade Louis Foucher de Careil commanded the corps artillery, 38 guns in four foot and two horse artillery batteries at full strength. Smith itemized Colbert-Chabanais' 6th Corps cavalry but repeated Trelliard's list of regiments, which was clearly a misprint. Historian Francis Loraine Petre wrote that General of Division Nicolas Léonard Beker's 1,200-strong 5th Dragoon Division was also present, but did not note its composition. Petre mentioned Beker and Trelliard, but not Colbert-Chabanais. Petre stated that Beker led the 5th Division. Digby Smith placed Beker in charge of the 2nd Dragoon Division and listed the 3rd, 4th, 10th, 11th, 13th, and 22nd Dragoon Regiments as part of this unit. These units are identical to Grouchy's division. General of Brigade Joseph Augustin Fournier Marquis de D'Aultane was the acting commander of the 3rd Division of Davout's corps. This unit was made up of two brigades. General of Brigade Claude Petit led the 2-battalion 12th Line Infantry Regiment and the 3-battalion 21st Line Infantry Regiment. General of Brigade Nicolas Hyacinthe Gautier directed the 25th and 85th Line Infantry Regiments, two battalions each. General of Division Louis Michel Antoine Sahuc led the 4th Dragoon Division, which only had one brigade present. General of Brigade Jacques Léonard Laplanche commanded the 15th and 25th Dragoon Regiments. Fournier had 70 chasseurs à cheval, 100 dragoons, and only one artillery piece attached to his command. The rest of the corps cavalry was at Gołymin. Bennigsen commanded Ostermann-Tolstoy's 2nd Division, Sedmoratski's 6th Division, and elements of the 3rd and 4th Divisions. The 2nd Division had three infantry and one cavalry brigades. Major General Nikolai Mazovsky
