Rear Admiral Jackson commanded Allied naval forces in the Eastern Mediterranean. For Third Gaza, the force was composed thus:
Grafton British light cruiser (model 0)
Raglan British monitor (model 0) 2 x 14-inch; 2 x 6-inch
M15 British monitor (model 0) 1 x 9.2-inch
M29 British monitor (model 0) 2 x 6-inch
M31 British monitor (model 0) 2 x 6-inch
M32 British monitor (model 0) 2 x 6-inch
Empress British seaplane carrier (model 0)
City of Oxford British seaplane carrier (model 0)
Raven II British seaplane carrier (model 0)
Staunch British destroyer
Comet British destroyer
Arbalète French destroyer
Voltigeur French destroyer
Coutelas French destroyer
Fauconneau French destroyer
Hache French destroyer
I doubt that including the destroyers will be of much use given that we are including the naval vessels for the purpose of shore bombardment.
