Tenth Destroyer Flotilla (Royal Navy)

The Tenth Destroyer Flotilla was a formation of destroyers of the Royal Navy instituted in mid-December, 1914. It fought as part of the Harwich Force throughout the war.

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.

February, 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.

June, 1915

Medea, Medusa, Miranda and the 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.

July, 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.

August, 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.

Battle of Jutland

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

Two fought with ?

• Moorsom, Commander John Coombe Hodgson
• Morris, Lieutenant-Commander Edward Sidney Graham

And two were temporarily attached to the Thirteenth Destroyer Flotilla:

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

June, 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.

February, 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.

March, 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.

April, 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 May, however.

"R" class destroyer Skate has also left, next to appear in June 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.

Setter has been lost to a collision with Sylph on 17 May. Sturgeon has left, to appear next with the Eleventh Destroyer Flotilla in August.

Newly-completed destroyers Sceptre, Tetrarch and Thisbe have joined.

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

June, 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.

August, 1917

Recruit was lost to a mine on 9 August.

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

September, 1917

A shuffle has brought in the new flotilla leader 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 November, 1917 and February, 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 around November.

November, 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.

December, 1917

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.

January, 1918

Four paddle sweepers have joined from the Sixth Destroyer Flotilla, and Undaunted has departed to join the Fifth Light Cruiser Squadron, also part of the Harwich Force.

Scott has now arrived, but Nimrod has gone to a temporary assignment with the Eleventh Destroyer Flotilla and Shakespeare is no longer marked as second in command.

The Tenth is thus now four flotilla leaders, twenty-one "R" class destroyers and four paddle sweepers.

Sharpshooter and Sturgeon have returned. Skate has joined.

The flotilla strength is four flotilla leaders, twenty-four "R" class destroyers and four paddle sweepers.

January, 1919

The end of the war brings a draw-down in fighting capacity and an increase in mine clearance forces, with two more sweeping flotillas being formed.

The end of the war has allowed eight destroyers to do what they always wanted to do: teach! Some have joined torpedo schools at various ports; Satyr at Devonport, Skate at Portsmouth, and Springbok at the Nore, with Skilful to join her "shortly". Others have joined gunnery schools; Sharpshooter at Portsmouth, and Starfish and Stork at the Nore. Sturgeon has gone to Dartmouth College.

The flotilla strength is now four flotilla leaders, sixteen "R" class destroyers and eighteen paddle sweepers.

February, 1919

The flotilla has ceased to exist by name. The other ships have been cast to the winds.

Most of the fighting ships were sent to active formations of the post-war Navy. Tetrarch, Thruster and Truculent remain part of the Harwich Force, but without a flotilla designation of any kind. The sweeping flotillas seem to remain in Harwich, but not as part of the Force. Montrose and Swallow have gone to the Sixth Destroyer Flotilla in the Mediterranean. Spenser and Shakespeare are leading the Second Destroyer Flotilla and Bruce the Seventh Destroyer Flotilla. The Fourth Destroyer Flotilla has swiped the Radiant, Redoubt, Retriever, Sylph, Taurus, Teazer and Tempest. Redgauntlet and Sceptre went to the Fifth Destroyer Flotilla.

Others have been placed in reserve; Sybille and Thisbe at the Nore, Torrid at Devonport, ...

Flotilla is Dis-established
