Hi, I have read that in Britain in 1940 there were no armies and army groups, instead there were corps, area commands, and the GHQ (or Commaner-in-Chief, Home Forces). South-Eastern England seems to have been either Aldershot Command (later renamed South-Eastern Command) or Southern Command. Logically the command structure would be GHQ -> Area Command -> Corps commands -> Divisions and Brigades. However in the south-east there seem to have been the GHQ reserve, plus various corps, divisions, and brigades that were under one command or another, or somewhat independant. How was it all supposed to work? As I understand it, the Area Commands were mainly regimental training organisations that had been charged with local defence so the regular army corps units may have seen their line of command coming direct from GHQ? Superficially it sounds to me like the organisation of the German defence of Normandy, with Hitler controlling some units, von Rundstedt some others and Rommel the rest.
