At either 3:00 pm or 3:30 pm Otto Karl Lorenz von Pirch's 1st Infantry Brigade and Heinrich Wilhelm von Horn's 7th Infantry Brigade arrived at Fontenelle-en-Brie on the Château-Thierry highway. Because of the poor condition of the roads, the Prussians only had brigade Batteries Nrs. 2 and 3 armed with 6-pounders. The heavier cannons were left behind with the 8th Brigade at Château-Thierry. Fearing the appearance of MacDonald's forces in his right rear, Yorck also sent his remaining infantry brigade back to hold Château-Thierry. The Prussian reserve cavalry deployed near Fontenelle though it lacked its artillery. Pirch deployed his brigade in two lines between Fontenelle and the hamlet of Tourneux farther east. After waiting for Horn's brigade to close up behind him, Pirch began attacking toward the Bailly and Plenois woods. Sacken ordered his two reserve heavy batteries to support the Prussian advance. At the same time, Michel's Old Guard division reached the battlefield and was committed to the fight against Yorck.
