The French cavalry prevailed, driving the Prussian first line back into its second line, and causing both to retreat in confusion. The French cavalry seized two cannons and a howitzer. Yorck ordered the 1st and 7th Brigades to retreat, which they did in good order. The 15th Silesian Landwehr Regiment shifted to La Trinit farm on the left flank. Many of its soldiers became the victims of French cavalry later in the day. There was also a Russian jäger battalion near La Trinit farm. Forming the rear guard, the Leib Regiment was cut off by a French dragoon regiment, but it made a bayonet charge and broke free. Two battalions of Old Guard Foot Grenadiers and the duty squadrons pressed back the Prussian right flank under Prince William almost to Château-Thierry. Covering the Allied right flank, Heidenreich formed his two regiments into square and tried to retreat. After his troops fired away all their ammunition, they were overrun. Heidenreich and most of his brigade were captured, along with three cannons.
