HMS Decoy was a Daring-class torpedo boat destroyer built for the Royal Navy, launched on 7 February 1894 by John I. Thornycroft & Company at Chiswick. The vessel served primarily in home waters, including participation in the 1896 British Naval Manoeuvres as part of the Channel Fleet operating from Berehaven, southern Ireland. She was also employed as an instructional tender to the gunnery school ship Cambridge until August 1901, reflecting her role in training and fleet exercises. Design-wise, Decoy was equipped with multiple torpedo tubes, characteristic of early torpedo boat destroyers. However, her bow torpedo tube proved largely ineffective in practice, especially at high attack speeds, as it tended to overtake its own torpedo, reducing operational efficiency. Additionally, the placement of the tube compromised living quarters and made the bridge vulnerable to flooding during maneuvers. Throughout her service, Decoy was based at Plymouth as part of the Devonport instructional flotilla, with her commanding officers including Lieutenant Cyril Asser from February 1902, followed by Lieutenant Henry Ralph Heathcote in July 1902, and later Lieutenant L. J. I. Hammond from August 1902. She participated in the fleet review at Spithead on 16 August 1902 for King Edward VII’s coronation. During late August 1902, she temporarily served as a tender to Cambridge again, before returning to the instructional flotilla. Tragically, HMS Decoy was lost on 13 August 1904 in a collision with the destroyer HMS Arun off the Scilly Islands during night exercises. One crew member was killed, and the remaining 40 were rescued by Arun and Sturgeon. The subsequent courts martial held aboard the battleship HMS Conqueror attributed blame to Commander Reginald Tyrwhitt of Arun, with an appeal dismissing neglect but confirming that both vessels had been hazarded. Her sinking marked a significant event in early naval operational history, highlighting the risks of night exercises and the importance of navigation safety.
