 By 23 March , Jourdan had his headquarters in the vicinity of Stockach . He had recalled Barthélemy Ferino from the far right flank ; Ferino had retreated along the coast of the Überlingen Lake , the northwestern finger of Lake Constance , to be in position at the close right flank , adjacent to Souham 's division . Lefebvre , wounded at Ostrach , was unable to take the field himself , and Laurent Saint Cyr commanded the left flank . When Jourdan considered his position , he felt it too extended , so he drew back further behind Stockach , toward Engen , where he could concentrate his force . The first division camped near the Hohentwiel , the 11th @-@ century fortress overlooking the marshes at the westernmost point of the Lake Constance . The second division , the advanced guard , and a cavalry division were camped on the heights above Engen . The third division was camped by Leibtengen ( Liptingen , the French called it ) , and Neuhausen . Vandamme and his small corps worked themselves discreetly into a position behind the Austrian right flank . Jourdan established his headquarters at Engen .
