I have a selection of envelopes sent between my mother and father in law during WW2. The letters from Dad have comments such as “passed by examiner” They mention Base 1236 and 1221, a third is identified as "Woodbrook", which I understand was a base in Port of Spain Trinidad. and finally one is marked naval censor. The envelopes are dated 1943 and are post marked variously Trinidad, Surinam and British Guiana. We think Dad arrived in Trinidad after having survived being torpedoed at least once, although we do not know the name of the ship he arrived on nor any of those whose torpedoing he survived (he claimed to have survived 3 times). Does anyone know if enlistment papers from Woodbrook survive of if there are lists surviving of peoplewho arrived in circumstances like Dad?
