The Eleventh Destroyer Flotilla was a formation of destroyers of the Royal Navy first instituted in September, 1915.

History

In 1916, it was comprised of M class destroyers whose 104 torpedo test runs in the first half of that year proved 91% probable to endanger the enemy.^[1]

A photo in March claims to show ships of the flotilla some time in 1917. While Prince may be incorrectly identified as a member of the flotilla, that photo seems to show:^[2]

• Kempenfelt G.10 (flagship)
• Marne GO.5 (or G.05 per Dittmar/Colledge)
• Prince G.43
• Marmion
• Morning Star

September, 1915

The flotilla appears for the first time in the Supplement to the Monthly Navy List, becoming the fourth flotilla attached to the Grand Fleet. Its small initial size (a flotilla leader, seven "M" class destroyers, and a depot ship shared with the Second Destroyer Flotilla) augurs future growth. The ships all appear to be new in service, though Kempenfelt, Mandate and Michael were listed with a miscellaneous status in the August edition.^[3][4]

October, 1915

New destroyers Manners, Martial and Milbrook have brought the strength to a flotilla leader, ten "M" class destroyers, and a depot ship shared with the Second Destroyer Flotilla.^[5]

November, 1915

The newly completed H.M.S. Castor has come to act as flotilla cruiser. Mounsey, Mystic and Ossory arrive to bring the strength to a cruiser, a flotilla leader, thirteen "M" class destroyers, and a shared depot ship.^[6]

December, 1915

Magic and Minion arrive to bring the strength to a cruiser, a flotilla leader, fifteen "M" class destroyers, and a shared depot ship.^[7]

January, 1916

Musketeer joins to bring the strength to a cruiser, a flotilla leader, sixteen "M" class destroyers, and a shared depot ship.^[8]

This arrangement would apply until April, 1916.^[9]

April, 1916

Broke has joined to bring the strength to a cruiser, two flotilla leaders, sixteen "M" class destroyers, and a depot ship which appears to be now exclusively the Eleventh's.^[10]

May, 1916

Castor now bears Commodore (F) and Kempenfelt is designated as second-in-command. Broke has departed to become second-in-command of the Fourth Destroyer Flotilla.

Flotilla strength is now a cruiser, a flotilla leader, sixteen "M" class destroyers, and a depot ship.^[11]

The flotilla would emerge from the Battle of Jutland with some ships damaged but without loss, allowing this arrangement to apply until September, 1916.^[12]

Battle of Jutland

Main article: Eleventh D.F. (Royal Navy) at the Battle of Jutland

Only Marmion and Musketeer missed participating in the battle, giving the flotilla 14 "M" class destroyers and two leaders, organised as follows^[13] under the commanders given in the Official Despatches.^[14]

• light cruiser Castor, Commodore (F) James R. P. Hawksley
• flotilla leader Kempenfelt, Commander Harold E. Sulivan
  • Ossory, Commander Harold V. Dundas
  • Mystic, Commander Claud F. Allsup
  • Moon, Commander (Acting) William D. Irvin
  • Morning Star, Lieutenant-Commander Hugh U. Fletcher
  • Magic, Lieutenant-Commander Gerald C. Wynter
  • Mounsey, Lieutenant-Commander Ralph V. Eyre
  • Mandate, Lieutenant-Commander Edward McC. W. Lawrie
  • Marne, Lieutenant-Commander George B. Hartford
  • Minion, Lieutenant-Commander Henry C. Rawlings
  • Manners, Lieutenant-Commander Gerald C. Harrison
  • Michael, Lieutenant-Commander Claude L. Bate
  • Mons, Lieutenant-Commander Robert Makin
  • Martial, Lieutenant-Commander Julian Harrison
  • Milbrook, Lieutenant Charles G. Naylor

At 10.5 at night, the Eleventh was five miles from the Second Battle Squadron, bearing about Green 169 when it encountered the German battlecruisers. Castor, Marne and Magic exchanged fire at just 2,000 yards and each fired a torpedo and turned away to port. Castor lost her W/T and was unable to direct the flotilla to attack more generally. Compounding this, some destroyers worried that the battlecruisers were British.

Commander Harold Ernest Sulivan, commanding Kempenfelt in the battle, was mentioned in despatches on 15 September, 1916 for his leadership at Jutland, "as 2nd in Cd of Flotilla he manoeuvred his half very ably & at night when Castor could make no signals owing to damage by gun-fire, he very ably turned his half flotilla & kept clear of first half flotilla manoeuvring.".^[15]

At 0.15 a.m., Castor encountered a destroyer on her bow and fired on it with gusto at point blank range. Its disappearance was taken as a sign that it was surely sunk.^[16]
