List of ships sunk by submarines by death toll

While submarines were invented centuries ago, development of self-propelled torpedoes during the latter half of the 19th century dramatically increased the effectiveness of military submarines.

Heavy casualties occurred when submarines sank large passenger ships converted into military transports, such as the Wilhelm Gustloff, that were overloaded with soldiers, prisoners, or refugees.

Initial submarine scouting patrols against surface warships sank several cruisers during the first month of World War I. Incidental submarine encounters with merchant ships were performed by signalling ships to stop, then sinking them after evacuation of the crew, in accordance with international law. After unrestricted submarine warfare began in February 1915, any ship could be sunk unexpectedly from the heavy underwater hull damage inflicted by torpedoes. Many large ships sank without their crews being able to alert friendly forces in time, and the submarines which sank them were too small to rescue more than a few survivors.[1]

Many personnel casualties continued through World War II, and there have been a few later sinkings.
