Kutusov saw the danger: the allies had advanced so many men into the gap in the French lines that they had left their own center exposed. He tried to turn back the last troops heading south, but it was too late. By 11:00 A.M. the French had retaken the heights. Worse, French troops had come up from the southwest to reinforce the southern position and prevent the allies from surrounding the French. Everything had turned around. Through the town of Pratzen, the French were now pouring through the allied center and were swiftly moving to cut off the retreat of the allied troops to their south.
