Olmütz (Seven Years' War).

This place was besieged by Frederick the Great, May, 1758. Having insufficient troops to completely invest the place, Frederick's task was a difficult one, and Marshal Daun was able to keep communications open, and supply the town with provisions. After a siege of seven weeks, the Austrians captured a convoy of 4,000 waggons, under the escort of Landon, destined for the Prussian army, and Frederick was forced by this loss to raise the siege, and retire.
