Soon after he took command, Home Forces had to allocate several divisions to Paget's 21st Army Group and begin training for the Allied invasion of Normandy, then to take place in May 1944. The remaining divisions fell into three categories, with the 38th, 45, 47th and 55th Divisions being placed on the Lower Establishment, with a much reduced composition than a standard division. A further three divisions, the 48th, 76 and 80, were reserve formations, specifically for training and holding men before being sent on an overseas draft. The 77th was a holding division, created with the intention of retraining men returning from leave and released Prisoners of war (POWs). The 61st Division was the only field formation that did not transfer to the 21st Army Group and in the event never served overseas.
