Francis Martin-Leake

Leake was still commanding HMS Pathfinder when World War I broke out and continued to serve as its commander until the SM U-21 sunk the ship off the Firth of Forth.^[2][3] Leake stayed in the ship as it was sinking but was picked up and saved as he states:

The torpedo got us in our forward magazine and evidently sent this up, thereby killing everyone forward... She (Pathfinder) then fell over and disappeared leaving a mass of wreckage all around, but I regret very few men amongst it, for at the time they were all asleep on the mess decks and the full explosion must have caught them, for no survivors came from forward.^[2]

On 6 October he was sent to Portsmouth to serve in HMS Victory and to train up Admiralty M-class destroyers. He then proceeded to command HMS Achilles on 19 February 1915.^[1] He was appointed as an additional commander to HMS Royalist on 20 June 1917 as a 2nd Class Commodore of the chief of staff of the Commander-in-Chief of the Coast of Ireland.^[1] Lewis Bayly described Leake as "a most exceptional man, for everyone loved the little Commodore".^[4] Leake also participated at the Action of 16 March 1917 while commanding HMS Achilles and managed to sink SMS Leopard and killing Korvettenkapitän Hans von Laffert.^[5]

Leake's appointment in Ireland expired on 1 June 1919 and was sent to command HMS King George V as Chief Staff Officer to Vice-Admiral Henry Francis Oliver as Leake was promoted to Vice-Admiral at some point after the war.^[1][6][7] On 25 May 1920 Leake got himself injured in a motorcycle accident but recovered on 5 August.^[1] Leake was placed on the retirement list on 19 November 1921 and died in Ware, Hertfordshire on 21 January 1928 after a three-year battle with dementia paralytica.^[1]
