Operation Warhorse

'Warhorse' was a British radio deception planned by Colonel David Strangeways' 'R' Force of General Sir Bernard Montgomery’s Allied 21st Army Group to attract the attention of the Germans toward the area of Nijmegen in the occupied Netherlands (November/December 1944).

The plan was cancelled after the Germans had broken the area’s dikes and flooded large area, thereby rendering the entire region unsuitable for military operations.
