Model and von Rundstedt both believed aiming for Antwerp was too difficult, given Germany's lack of resources in late 1944. At the same time they felt that being just defensive would only delay defeat. They developed plans that did not aim to cross the Meuse River; Model's being "Unternehmen Herbstnebel" (Operation Autumn Mist) and von Rundstedt's "Fall Martin" ("Plan Martin").
