On this day 100 years ago, the 37 vessels of convoy TU26 set sail from Leith for Immingham on the Humber.
Converted passenger ferry HMAPV Dirk was at the head of the convoy. It had 2 ships alongside: HMS Bat to her port side, and HMS Petrel to her starboard side. 2 escorting trawlers sailed behind HMS Petrel, while behind HMS Bat were 3 trawlers and then HMS Ouse.
The Dirk will not make it to Immingham, as she will be torpedoed and sunk by the U-Boat UC-75 near Flamborough Head at 01:30. And one of the convoy's merchant vessels, the SS Caroline will also founder.
