text:  Klenau 's victory was a singular success . On 14 October Mack sent two columns out of Ulm in preparation for a breakout to the north : one under Johann Sigismund Riesch headed toward Elchingen to secure the bridge there , and the other under Franz von Werneck went north with most of the heavy artillery . Recognizing the opportunity , Marshal Michel Ney hurried the rest of his VI Corps forward to re @-@ establish contact with Dupont , who was still north of the Danube . In a two @-@ pronged attack Ney sent one division to the south of Elchingen on the right bank of the Danube . This division began the assault at Elchingen . At the same time another division crossed the river to the east and moved west against Riesch 's position . After clearing Austrian pickets from a bridge , the French attacked and captured a strategically located abbey at the top of the hill at bayonet point . The Austrian cavalry unsuccessfully tried to fend off the French , but the Austrian infantry broke and ran . In this engagement alone , the Austrians lost more than half their reserve artillery park , 6 @,@ 000 ( out of 8 @,@ 000 total participants ) dead , wounded or captured and four colors . Reisch 's column also failed to destroy the bridges across the Danube .
