The Seehund (seal) was the most successful of several Nazi attempts to perfect a midget submarine. Operated by two men and carrying two underslung torpedoes, the Seehund was used very effectively in the waning months of World War II, sinking over 120,000 tons of allied shipping. Their small size and rapid evasive action made them virtually undetectable and depth charges seemed to bounce off of their resilient hulls. In the final months of the war, the Seehunds were used as “butter boats” to replenish the dwindling supplies of German garrisons stranded along the coast.
