This map has been figuring in my head for some time and offers some interesting possibilities.
After the fall of East Prussia the soviets proceeded with landings of troops and tanks on the frische nehrung (vistula spit) at the 26th of april 1945. Both the frische nehrung and the vistula estuary at the base of the frische nehrung was packed with wounded soldiers and fleeing civilians waiting to be picked up by the german fleet and the germans put up determined defense with the last tanks, equipment and soldiers to slow down the soviet attempts to destroy the bridgehead.
From what I can remember from reading the sPzAbt.511 (former 502) lost their last Tiger I (which was shipped from East Prussia and repaired) on the frische nehrung after inflicting the soviets some losses, aswell as the 4.Pz-Div sending some reinforcements to the frische nehrung - which leave some room for vehicle fighting. I will have to dive into my library for more specific information.
Information about the fighting.
Vehicle of interest; Panzerspahwagen II Ausf L Luchs (used in the 4th Panzer Division since 1943 and was sent into the fighting on the frische nehrung)
This light reconnaissance tank saw service until the end of the war on both the Eastern and Western Front with Panzer-Aufklarungs-Abteilungen (armored reconnaissance detachments) of Wehrmacht and Waffen-SS. Reported users include 116th Panzer Division on the Western Front and 3rd, 4th and 6th Panzer Division on the Eastern Front.
