In the months leading up to the invasion, the Allies conducted Operation Bodyguard, the overall strategy designed to mislead the Germans as to the date and location of the main Allied landings. Operation Fortitude included Fortitude North, a misinformation campaign using fake radio-traffic to lead the Germans into expecting an attack on Norway, and Fortitude South, a major deception designed to fool the Germans into believing that the landings would take place at Pas de Calais in July. A fictitious First U.S. Army Group was invented, supposedly located in Kent and Sussex under the command of Lieutenant General George S. Patton. The Allies constructed dummy tanks, trucks, and landing craft, and positioned them near the coast. Several military units, including II Canadian Corps and 2nd Canadian Division, moved into the area to bolster the illusion that a large force was gathering there. As well as the broadcast of fake radio-traffic, genuine radio messages from 21st Army Group were first routed to Kent via landline and then broadcast, to give the Germans the impression that most of the Allied troops were stationed there. Patton remained stationed in England until 6 July, thus continuing to deceive the Germans into believing a second attack would take place at Calais. Military and civilian personnel alike were aware of the need for secrecy, and the invasion troops were as much as possible kept isolated, especially in the period immediately before the invasion. One American general was sent back to the United States in disgrace after revealing the invasion date at a party.
