HMS Nepean (1916) was a repeat M class destroyer that served with the Grand Fleet from 1916 to March 1918, then with the 4th Destroyer Flotilla at Devonport for the rest of the war.
The Nepean was ordered as part of the Second War Programme of early November 1914. She was laid down at Thornycroft in February 1915, launched on 22 January 1916 and completed in March 1916.
1916
The Nepean served with the 13th Destroyer Flotilla of the Grand Fleet from May 1916 to March 1918.
On the eve of Jutland the Nepean was with the Thirteenth Destroyer Flotilla that was with the battlecruiser fleet at Rosyth, but she remained in harbour.
1917
On 15 April 1917 the Nepean salvaged the trawler Breadalbane.
On 30 April a submarine fired a torpedo at the Nepean while she was close to May Island (probably UC-77).
On 3 May the cruisers Sydney and Dublin and the destroyers Nepean, Pelican, Pylades and Obdurate left Rosyth to sweep two of cleared channels in the coastal minefields. On the morning of 4 May this force encountered the Zeppelin L.43, and the two cruisers opened fire on her. The Zeppelin wasn’t operating alone, and the British soon sighted U-boats. The British turned to the north-west to avoid being drawn onto a possible trap. The Zeppelin followed. At 11.50 the Nepean and Pelican were ordered to move around to the south-west, and the British soon had the airship surrounded. However neither side was able to inflict damage – the Germans dropped several bombs but all missed, and the British were unable to score any hits with their gunnery.
On 25 July the Grenville, Obdurate, Pelican, Nepean and Orpheus were escorting a convoy of five empty oilers heading from Scapa Flow to Texas when it was attacked by UC-41. The U-boat was able to sink the SS Oakleaf, although the entire crew were rescued.
When the Germans attacked a Scandinavian convoy on 16 October, sinking the destroyers Mary Rose and Strongbow, the Nepean was one of four destroyers from the 13th Flotilla that were allocated to the 1st Cruiser Squadron at Rosyth. The squadron, made up of the Courageous and Glorious (in their original battlecruiser form) was sent to try and catch the Germans as they retreated after the battle, but without success.
During the Second battle of Heligoland Bight (17 November 1917) the Nepean was at sea with the 1st Battle Cruiser Squadron, but her formation never reached the battle.
1918
From April-December 1918 she served with the 4th Destroyer Flotilla at Devonport.
In December 1919 she was in the charge of a Care and Maintenance Party on the Nore.
She was sold to be broken up in November 1921.
