"Generalfeldmarschall" (Field Marshal) Walther Model and Field Marshal Gerd von Rundstedt were ordered to lead the attacks. 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"). The two field marshals showed their plans to Hitler, who rejected them in favor of his "big solution".
