 After Rokossovsky's 2nd Belorussian Front had broken out of their bridgehead, General Heinrici disobeyed Hitler's direct orders and allowed von Manteuffel's request for a general withdrawal of the III Panzer Army.By 29 April, Army Group Vistula Headquarters staff could no longer contact the IX Army, so there was little in the way of coordination that Heinrici's staff could still to do.As Heinrici had disobeyed a direct order from Hitler (in allowing von Manteuffel to retreat), he was relieved of his command.
