During April 1942, 222 Group in Ceylon had four Dutch Catalinas under its command. One of them, Y-56 (Lt Hamers), operated from Addu Atoll from 4 to 9 April on an “important mission in connection with Naval Forces”. Apart from the Koggala ORB, what British records might contain any information on what Y-56 was doing at Addu Atoll?

Thanks,
