Initially commanded by General Franz von Roques, it was an area of military jurisdiction behind Wehrmacht's Army Group North.
The Group North Rear Area's outward function was to provide security behind the fighting troops.
In the words of historian Michael Parrish, the army commander "presided over an empire of terror and brutality".
Its headquarters was subordinated to Army Group North, while also reporting to the Wehrmacht's Quartermaster General Eduard Wagner, who had the overall responsibility for rear area security.
The so-called anti-partisan operations in "bandit-infested" areas amounted to destruction of villages, seizure of livestock, deporting of able-bodied population for slave labour to Germany and murder of those of non-working age.
