Early this morning, shortly after midnight the steamship Hanna Larsen is sighted by the German submarine UC-39. The steamer stops and the submarine dives to approach her submerged. The Hanna Larsen now attempts to escape by “zig-zagging” but the German craft comes to the surface and opens fire at the steamer that again stops and lowers her boats. The U-boat sends men over to the British ship to sink her with bombs making the master and chief prisoners.
At 13:00, having sunk a Norwegian steamer in the meantime, UC-39 again comes to the surface and opens fire on another steamer, but this time her fire is almost immediately answered by the British destroyer HMS Thrasher (Lieutenant Commander E M Hawkins). UC39 dives, but not soon enough, as a depth charge shakes her so badly that water pours into her conning tower and control room. She then rises sharply to the surface only to have the destroyer rake her fore and aft. In spite of the fact that her captain has by now been killed, the submarine continues to make good speed and therefore the destroyer continues to fire. Finally, the destroyer hails the U boat through a megaphone to stop and this being done, fire is ceased and seventeen German survivors are taken aboard the destroyer. The two British prisoners are also rescued uninjured. The destroyer HMS Gurkha (Lieutenant Harold Courtenay Woollcombe-Boyce killed at age 29) strikes a mine off Dungerness and sinks with the loss seventy-five. Five of her crew are saved.
- Seaman George Duchart RNR killed at age 19. His brother died of wounds in October 1915.
The destroyer HMS Liberty (Lieutenant Commander P W S King) rams and sinks the German submarine UC-46 southeast of the Goodwins.
