Heeresgruppe Weichsel
At some point on 28 April or 29 April, General Heinrici, Commander-in-Chief of Army Group Vistula, was relieved of his command after disobeying Hitler's direct orders to hold Berlin at all costs and never order a retreat, and was replaced by General Kurt Student. General Kurt von Tippelskirch was named as Heinrici's interim replacement until Student could arrive and assume control. There remains some confusion as to who was in command, as some references say that Student was captured by the British and never arrived. Regardless of whether von Tippelskirch or Student was in command of Army Group Vistula, the rapidly deteriorating situation that the Germans faced meant that Army Group Vistula's coordination of the armies under its nominal command during the last few days of the war was of little significance.
