The Campaign of Ulm was a French defeat over the Austrians in 1805. In August 1805 the adhesion of Francis I to the third coalition involved Napoleon in war with Austria as well as with England and Russia. The Austrian forces under General Mack, instead of awaiting the arrival of the Russians, had taken up a position between Ulm and Memmingen, and in September Napoleon formed the plan of cutting Mack off from the Russians and Vienna. To this end he passed all his armies, aggregating 190,000 men, swiftly through Hanover and the smaller German states and reached the Danube to the rear of Mack who was taken by surprise. Napoleon succeeded in hemming in Mack with 60,000 men at Ulm, the investment being completed on October the 14th and Mack capitulated three days later. Research Campaign of Ulm
