“Only 101 men were saved out of 800 on board.”
As the Germans were evacuating the Baltic states and East Prussia towards end of WWII, they lost over 9,000 people - mainly civilians (rescuing less than 1,000) when Soviets torpedoed one ship (Wilhelm Gustloff). They lost thousands on other ships sunk in the same period, but this one to this day is probably the worst naval disaster in history.
