December, 1916

A change of names with another flotilla is being effected this month. The flotilla serving with the Portsmouth Defence will be keeping Dolphin, S 1 and K 3 while picking up two other coastal submarines and the name Sixth Submarine Flotilla. It is not clear what has become of B 1 and B 5.

The new Second Submarine Flotilla is resuming the role previously assigned the Sixth, serving with another submarine and a destroyer flotilla under Rear-Admiral commanding East Coast of England:[30]

The flotilla is apparently disbanded in this month or October. Bonetta would be moved to the Fourteenth Submarine Flotilla, but I see no record of the submarines ever being listed again.[50]

March, 1919

Back as one of six flotillas supporting the Grand Fleet in the post-war navy, the Second has a leader, a depot ship and seven "K" class submarines.[51]
