 To prevent this , Charles executed an orderly withdrawal in four columns through the Black Forest , across the Upper Danube valley , and toward Bavaria , trying to maintain consistent contact with all flanks as each column withdrew through the Black Forest and the Upper Danube . By mid @-@ July , the column encamped near Stuttgart . The third column , which included the Condé ’ s Corps , retreated through Waldsee to Stockach , and eventually Ravensburg . The fourth Austrian column , the smallest ( three battalions and four squadrons ) , under General Wolff , marched the length of the Bodensee ’ s northern shore , via Überlingen , Meersburg , Buchhorn , and the Austrian city of Bregenz .
