When Canadian troops embarked for Europe on 30 September 1914, a Burgess-Dunne seaplane was loaded aboard for England.

[4] She was sunk 7 miles north of Inishtrahull, Ireland with the loss of 15 crew and passengers and 440 horses on 16 August 1917.

[5] Athenia was a defensively armed merchantman, and she was torpedoed some 6 metres from her stern by SM U-53 while steaming at 20 knots, then abandoned and sunk.

[6] On her final voyage she was on passage from Montreal to Glasgow, and was in course of repatriating some members of the crew of HMHS Letitia (she had picked up at Halifax, Nova Scotia) when she was torpedoed; relatives were required to travel to Donegal to identify the bodies.

The area was depth-charged in World War II to prevent it becoming a hiding place for U-boats on the seabed.
