Moreau wanted to retreat through the Black Forest via the Kinzig river valley, but Nauendorf blocked that route. Instead, Saint-Cyr's column led the way over the Höllenthal, breaking through the Austrian net at Neustadt and reaching Freiburg im Breisgau on 12 October. Moreau's supply trains took a route down the river Wiese to Hüningen. The French general wanted to reach Kehl farther down the Rhine, but by this time Charles was barring the way with 35,000 soldiers. For his trains to get away, Moreau needed to hold his position for a few days. The Battle of Emmendingen was fought on 19 October, the 32,000 French losing 1,000 killed and wounded plus 1,800 men and two guns captured. The Austrians sustained 1,000 casualties out of 28,000 troops engaged. Beaupuy and Wartensleben were both killed. There was some fighting on the 20th, but when Charles advanced on 21 October the French were gone.
