 The remaining 21,255 men were considered ineligible at that time for service abroad, for medical reasons, or for not being fully fit or fully trained, or for other reasons.Over the following six months, up to 75 per cent of these men would be deployed to reinforce 21st Army Group following the completion of their training and certification of fitness.Stephen Hart comments that, by September, the 21st Army Group "had bled Home Forces dry of draftable riflemen" after the losses suffered during the Normandy Campaign, leaving the army in Britain, with the exception of the 52nd (Lowland) Infantry Division, with just "young lads, old men, and the unfit".
