Project history

A repeat order for minesweeping sloops was placed in May 1915, but with heavier armament, in view of the likelihood of German raids on the sweeping flotillas. It was hoped to provide 120mm guns for them all, but the later ships had 102mm. In other respects they were virtually identical, and came into service in September-December 1915

Modernizations

1916 - 1917, all survived: + 2 DCT, 1 DCR

1916 - 1917, Begonia: was converted to decoy ship resembling a small coaster.

Naval service

She recommissioned on 9 August 1917 and used the names Dolcis, Jessop and Q10. She was sunk in collision with the large U-boat U151 off Casablanca 2.10.1917. Myrtle was mined in the Gulf of Finland during operations against the Bolsheviks 16.7.1919, Zinnia was transferred to Belgium in April 1920 and retained her name.
