9 May 1945
In late April 1945, the remaining prisoners were removed from Stutthof by sea, since Stutthof was completely encircled by Soviet forces. Again, hundreds of prisoners were forced into the sea and shot. Over 4,000 were sent by small boat to Germany, some to the Neuengamme concentration camp near Hamburg, and some to camps along the Baltic coast. Many drowned along the way. Shortly before the German surrender, some prisoners were transferred to Malmo, Sweden, and released to the care of that neutral country. It has been estimated that over 25,000 prisoners, one in two, died during the evacuation from Stutthof and its subcamps.
Soviet forces liberated Stutthof on May 9, 1945, and liberated about 100 prisoners who had managed to hide during the final evacuation of the camp.
