Supposedly arrived in Sicily from the United States in May 1944.

It was disposed of by announcing in July 1944 that the division had been disbanded. |

| 18th Airborne Division | | | 566th Parachute Infantry Regiment 567th Glider Infantry Regiment 570th Glider Infantry Regiment | Dervish (1945)Pastel Two | Dervish was an unrealized deception plan intended to further strain the German war effort in early 1945. It sought to depict a large-scale airborne threat to the strategically vital Stendal–Brandenburg–Wittenberg–Magdeburg region, with the airborne force possessing the resources to support itself for thirty days. Although Dervish ultimately came to nothing, the notional 18th Airborne Division was activated in the United States to support this effort, and plans were made to depict it being deployed to Europe. The 18th Airborne was later designated for use in Pastel, the deception plan to protect Operation Olympic, the planned invasion of Kyushu. |
| 21st Airborne Division | June – November 1944 | | 521st Parachute Infantry Regiment 277th Glider Infantry Regiment 278th Glider Infantry Regiment | Fortitude South | The division was initially depicted as being under the direct command of US 14th Army with its headquarters located in Fulbeck, Lincolnshire in June 1944. In the Pas de Calais landings it and the 9th Airborne Division were to be dropped behind the XXXVII Corps beachheads. In August 1944 it was notionally transferred to the direct command of First United States Army Group, where it assisted in the training of the U.S. 48th Infantry Division in air landing techniques. In the aftermath of Fortitude South, the notional U.S. 9th and 21st Airborne Divisions, the notional British 2nd Airborne Division, and the real United States 17th Airborne Division were used to depict an airborne threat to the Kiel-Bremen area, supporting Operation Market Garden. In November 1944 it was announced that the division had been merged with the 9th Airborne Division to form the 13th Airborne Division, a real unit that was about to be deployed to France. |

| 48th Infantry Division | June – December 1944 | | 80th Infantry Regiment 95th Infantry Regiment 146th Infantry Regiment | Fortitude South | The 48th Infantry Division was "created" in 1944 as an 'phantom division'. It formed part of Operation Quicksilver and Fortitude South II to replace the real 6th Armored Division when it moved to Normandy. The division was presented to the Germans as a well trained unit that had been formed at Camp Clatsop, Oregon, in 1942. Following training at the Desert Training Center and maneuvers in the Olympic Peninsula the division had guarded the ALCAN Highway before being shipped to England in June 1944, where Agent Garbo reported that the uncle of one of his agents (An American NCO in the ETO Services of Supply.) was a member of the division, which was not at the time he made the report under the command of either the First US Army Group or the 21st Army Group. After disembarkation, the division established its initial headquarters at Newcastle-under-Lyme in Staffordshire before moving to Woodbridge in Suffolk. There, as part of the U.S. XXXIII Corps (United States) of the US 14th Army it was assigned the role of following up the Pas de Calais landings. Following Fortitude South II the division was depicted as moving to Brockenhurst in Hampshire where it carried out air landing training in conjunction with the US 21st Airborne Division. In December 1944 the division was depicted as moving to Dundee in Scotland where it was disbanded at the start of 1945, with some soldiers being used as replacements for other units while a small cadre returned to the United States. |
