 Belgium was run by a German military government under General Alexander von Falkenhausen and Eggert Reeder until July 1944 , and then by Reichskommissar Josef Grohé until liberation . The German government levied the costs of the military occupation on the Belgians through taxes , while also demanding " external occupation costs " ( or " Anti @-@ Bolshevik charge " ) to support operations elsewhere . In total , Belgium was forced to pay nearly two @-@ thirds of its national income for these charges , a figure equaling 5 @.@ 7 billion Reichsmarks .
