75 per cent of these men would be deployed to reinforce 21st Army Group following the completion of their training and certification of fitness. For example, the two Liverpool Scottish battalions were used as training units and a source of reinforcements for other Scottish regiments. Entire units were also stripped from the division and deployed abroad; the 2nd Loyal Regiment (North Lancashire) (previously the 10th Battalion, Loyal Regiment) was transferred to Italy. While the 199th Brigade remained part of the division, it was attached to Northern Ireland District in July 1944. The same month, the division, minus the 199th Brigade, returned to the mainland and moved to southern Wales. The 199th Brigade, renumbered the 166th Brigade, physically rejoined the division in June 1945. In April 1945, the 304th and the 305th Infantry Brigades were attached to the division. These were recently converted anti-aircraft formations. The latter remained with the division for seventeen days, before being sent to the 21st Army Group. The former stayed with the division into May, and then deployed to Norway. In the final months of 1943 and through June 1944, the division's actual and notional moves were deliberately leaked by double agents as part of the "Fortitude North" segment of the Operation Fortitude deception, the effort to make the Germans believe that the notional 250,000-strong Fourth Army, based in Scotland, would assault Norway. The division was assigned to the fictional II Corps, which was notionally preparing to assault Stavanger. The division participated in this deception effort by maintaining wireless signals suggesting it was moving around the United Kingdom as part of the Fourth Army. The overall ruse of an attack on Norway was maintained through July 1944, the plan officially coming to an end in September. Historian Mary Barbier wrote "the evidence seems to indicate that [Fortitude North] was only partially successful" and "a heated debate has erupted over whether or not [the operation] was a success." The division then joined the II Corps's notional move south from Scotland to England, in June 1944, becoming part of "Fortitude South" to convince the Germans that the Normandy landings were a feint and the main Allied invasion would take place in the Pas-de-Calais with a force of 500,000 men. The deception aimed to persuade the Germans not to move the 18 divisions of the 15th Army from the Pas-de-Calais to Normandy. The division also provided the signal and
