Only one ship was sunk by U-boats on this day in 1915, T.&J. Harrisons' cargo ship Commodore. She was en route to Marseille, France in ballast when SMS U-33 began shelling the ship, since the ship attempted to escape further shells were fired until it came to a stop. Some reports claim that as the men were abandoning the ship that the U-boat continued to shell them, wounding five men in addition to the man killed in the initial attack.

There are other accounts that state that the U-33 came alongside the lifeboat and seeing the wounded men, refused to even provide basic first aid to them. They were set adrift and were not picked up until a day later.
