The siege of Dunkirk took place in the Autumn of 1793 when British, Hanoverian, Austrian, and Hesse-Kassel troops under the command of Prince Frederick, Duke of York besieged the fortified French border port of Dunkirk, as part as the Flanders campaign of the French Revolutionary Wars. Following a Coalition defeat at the Battle of Hondshoote they were forced to raise the siege and withdraw northeast.
