Tenth Destroyer Flotilla (Royal Navy)

The Tenth Destroyer Flotilla was a formation of destroyers of the Royal Navy instituted in mid-December, 1914.

History

Its formation was commanded on 15 December 1914 under leader Aurora with Dido as the depot ship and eight Beagles and all the M class destroyers presently available except Miranda and Meteor.

In 1916, it was comprised of M class destroyers armed with 21-in Mark II torpedoes.

March, 1915

The flotilla appears in The Navy List for the first time, under Commodore (T) in flagship cruiser Arethusa. It has a cruiser and nine "M" class destroyers.

Plans to add Tipperary to the Tenth may have been altered, as she is now part of the Third Destroyer Flotilla. Mansfield is seemingly now complete. The Tenth is one cruiser and twelve "M" class destroyers.

July, 1915

Medea, Medusa, Miranda and the [Acorn Class Destroyer (1910)|Acorn class destroyer]] Hope have joined (the latter for just the month), and Melpomene is slated to join "shortly" – she would actually appear in September. In the meantime, the Tenth is projected to be one cruiser and seventeen destroyers.

August, 1915

Hope is gone, noted in the catch-all bin of "miscellaneous ships in home waters or on detached service". Melpomene is still not actually joined. The Tenth is one cruiser and sixteen "M" class destroyers.

September, 1915

Melpomene has finally, in fact, joined. Nimrod has joined as a Flotilla Leader. The Tenth is one cruiser, a flotilla leader and sixteen "M" class destroyers.

Melampus has joined from "detached service" or what-not. On the other hand, Mastiff has departed to join the Eleventh Submarine Flotilla, destined to return in one month. For now, the Tenth is still one cruiser, a flotilla leader and sixteen "M" class destroyers.

Battle of Jutland

Just four destroyers from the flotilla were at the Battle of Jutland.

Two fought with ?

• Moorsom, Commander J. C. Hodgson
• Morris, Lieutenant-Commander E. S. Graham

And two were temporarily attached to the Thirteenth Destroyer Flotilla:

• Turbulent (lost), Lieutenant-Commander Dudley Stuart
• Termagant, Lieutenant-Commander Cuthbert P. Blake

As Turbulent had so very recently joined that she never was listed in the Navy List as part of the Tenth, the strength of the flotilla was not affected by the Battle.

July, 1916

Medea has moved out, briefly disappearing from the Navy List, but destined to appear with the Tenth Submarine Flotilla in November, 1916. Termagant's assignment is noted as being temporary.

The Tenth is now a cruiser, a flotilla leader and fifteen destroyers.

The newly-completed destroyers Phoebe and Simoom have joined. Dedicated cruiser Aurora has moved out to join the Fifth Light Cruiser Squadron, replaced in part by shared use of the Undaunted with the Ninth Submarine Flotilla, the Tenth's sister flotilla within the Harwich Force.

The Tenth is now a cruiser, a shared flotilla leader and seventeen destroyers.

March, 1917

Melpomene, Mentor, Meteor and Morris have moved out to join the Sixth Destroyer Flotilla of the Dover Patrol. Simoom seems to vanish from the Navy List for a full year until being listed with Twelfth Destroyer Flotilla in March, 1918.

Offsetting these losses and more, eight newly-completed destroyers have joined: North Star, Redgauntlet, Satyr, Setter, Skate, Stork, Surprise and Sylph.

The Tenth is now a cruiser, a shared flotilla leader and twenty modern destroyers.

April, 1917

The dissolution of the Ninth Destroyer Flotilla in this month gives the Tenth exclusive use of the flagship cruiser it had been sharing with that formation, and has also lifted its flotilla leader, Lightfoot.

A trend toward flushing out "M" class in favour of "R" class gains speed as Mastiff, Moorsom and Myngs leave to join the Sixth Destroyer Flotilla of the Dover Patrol while ten new "R" class destroyers join the Tenth: Radiant, Retriever, Redoubt, Sharpshooter, Skilful, Sturgeon, Sybille, Tempest, Thruster and Torrent.

The Tenth is thus now a cruiser, two flotilla leaders and twenty-seven modern destroyers.

May, 1917

The flotilla continues a trend toward enrichment of the "R" class destroyer demographic. "M" class vessels Matchless and Miranda have gone to join the Sixth Destroyer Flotilla of the Dover Patrol, the former not to arrive before June, however.

"R" class destroyer Skate has also left, next to appear in July with the Eleventh Destroyer Flotilla, to be replaced by the newly-completed Recruit, Springbok, Torrid and Taurus.

The Tenth is thus now a cruiser, two flotilla leaders and twenty-eight modern destroyers.

July, 1917

Murray, North Star and Phoebe have left to join the Sixth Destroyer Flotilla of the Dover Patrol, leaving no "M"s in the Tenth.

Valkyrie has joined as a third flotilla leader, and Teazer has joined.

The Tenth is thus now a cruiser, three flotilla leaders and twenty-four destroyers, all of the "R" class.

This arrangement would apply until September.

September, 1917

Recruit has been lost to a mine on 9 August.

The Tenth is thus now a cruiser, three flotilla leaders and twenty-three "R" class destroyers.

October, 1917

A shuffle has brought in the new submarine Shakespeare as second in command, sending Lightfoot to the Sixth Destroyer Flotilla.

Thisbe and Sharpshooter have been dropped without explanation, but they would reappear in December, 1917 and March, 1918, respectively.

Tornado and Ulleswater have entered service.

The Tenth is thus now a cruiser, three flotilla leaders and twenty-three "R" class destroyers.

This arrangement would apply until December.

December, 1917

Thisbe has returned from her two month absence.

Spenser has come in as a flotilla leader. It is not clear from the format, but she may also have the rank of second in command).

The Tenth is thus now a cruiser, four flotilla leaders and twenty-four "R" class destroyers.

January, 1918

Spenser now bears the Captain (D). Scott is to join "shortly".

Surprise, Tornado and Torrent were all mined on 23 December.

The Tenth is thus now a cruiser, four/five flotilla leaders and twenty-one "R" class destroyers.
