The sudden Austrian advance at dawn caused the 150-strong regiment of Carabiniers to retreat at the gallop. Saint-Cyr's light cavalry, led by Étienne Marie Antoine Champion de Nansouty, lost heart at seeing the heavy cavalry fleeing and fell back, leaving the French infantry at Eglingen without support. The Austrian horse fell on the flank of Lambert's brigade, routing its six battalions. This left Taponier's division with 12 battalions to face Charles' assault. At this moment Moreau arrived at Saint-Cyr's headquarters. Before riding off to consult with Desaix, the French army commander placed Bourcier's division in support nearby and agreed to have the Left Wing attack the Austrian right flank. Saint-Cyr deployed nine battalions at Dunstelkingen while keeping Lecourbe's three battalions to protect his right rear at Dischingen. At 9:00 AM the Austrians attacked this position but were beaten back. Their artillery set Dunstelkingen on fire but this actually helped prevent the Austrians from advancing. Moreau then returned from his meeting with Desaix to inform Saint-Cyr that the Left Wing's attack would be delayed until Delmas' division could be recalled from the extreme left.
