The Recollections of Desmond Gerrish

Joining the Royal Navy. I joined in September 1947 at age 16, as a Boy Seaman, 2nd Class. I went to HMS Ganges, a huge training barracks for boys (3,000 of us) on the estuary of the broad River Stour at Ipswich. Ganges trained only seamen and communication boys. Electrical engineers, stokers, cooks, stewards and medical boys all went to their own individual specialist barracks dotted around the UK.
