SM U-41[a] was one of the 329 submarines serving in the Imperial German Navy in World War I. U-41 engaged in naval warfare and took part in the First Battle of the Atlantic.

[3] U-41 stopped the 6,651 gross register tons (GRT) merchantman Urbino on 24 December about 70 miles from Bishop Rock.

After finding war material on board, the Germans put the merchant crew off the ship in the lifeboats.

U-41 was in the process of sinking Urbino with gunfire when, "Baralong", arrived on the scene at around 9:45, flying an American flag.

The crew of Baralong went through the motions of preparing a boat, while at same time readying for combat, and in doing so closed the distance to 700 yards and turned so her hidden guns were able to bear.

After other hits, U-41 listed then dived but then rose again before sinking - only Oberleutnant zur See Iwan Crompton (badly wounded) and the helmsman escaping[b] to be picked up along with the 42 from the Urbino by Wyandra.
