Harwich Force
The Harwich Force was a Royal Navy command during the First World War, based on the East Anglian port of Harwich.
History
The command was founded in April, 1914 as "Destroyer Flotillas of First Fleet," an administrative name it would sporadically bear for some time in the Navy Lists.[1]
From the outbreak of war, the Force was comprised of the Third Destroyer Flotilla (re-designated as the Ninth Destroyer Flotilla in September 1915) and the Tenth Destroyer Flotilla equipped with fast and modern ships and the Fifth Light Cruiser Squadron.
Around March, 1917, the Ninth Destroyer Flotilla would leave, but by this time 10 D.F. had been increased in strength to 27 destroyers whose modernity had been continuously refreshed. 5 L.C.S. would also be over twice as strong by this time, as well.

By May 1915, it was given the more aggressive-sounding name, Harwich Striking Force, then having the Fifth Light Cruiser Squadron with two light cruisers (with two others being completed) and two destroyer squadrons served by depot ship Dido, two light cruisers and two other leaders (one being completed), giving it a total of four light cruisers and thirty-two "L" and "M" class destroyers.[2]
