More than 7,000 die when the German transport ship Goya is sunk by a Soviet submarine.

Goya was a Norwegian motor freighter used as a troop transport by Nazi Germany and sunk with a massive loss of life near the end of World War II.

A submarine is a watercraft capable of independent operation underwater. The term "submarine" is also sometimes used historically or informally to refer to remotely operated vehicles and robots, or to medium-sized or smaller vessels. Submarines are referred to as boats rather than ships regardless of their size.
