The Austrians declined to launch any more serious assaults on Taponier's division and by 1:00 PM the contest degenerated into an artillery duel. Part of Lambert's brigade was rallied and reoccupied Heidenheim. The Austrians threatening the French right flank began withdrawing to Dillingen an der Donau. For the fourth time that day Moreau came to see Saint-Cyr, this time accompanied by Desaix. They informed their colleague that Delmas' division was not available yet and it was too late to attack the Austrian right that day. Everything would be ready the next day. Charles hoped that Moreau might concede defeat, but the morning of 12 August found the French army still in position. Charles then gave the order to fall back. Worried about the artillery ammunition shortage, Moreau did not attack Charles' right, but neither did he panic and retreat. Instead he held his position all day on the 12th waiting for confirmation that the Austrians were withdrawing across the Danube.
