Hi. I am looking at the period from 1910 to 1945, specifically submarines and RN activity in Hong Kong. The submarines flotillas were:
First Submarine Flotilla to the Sixteenth Submarine Flotilla and five others: Ambrose's Flotilla, Mediterranean Flotilla, Platypus's Flotilla, Vulcan's Flotilla, Hong Kong Flotilla
I am mainly interested in the Fourth Submarine Flotilla and the Hong Kong Flotilla.
They should be in a separate group, so that we have Royal Navy Ships, Royal Navy Submarines, Royal Navy Submarine Flotillas.
Thanks for your quick reply.
