Surgeon Rear-Admiral John R Muir, after his time aboard Tiger, was appointed medical officer in charge of British Weihaiwei on the northeast coast of China. In the Second World War, at the age of 66 and by then retired, he was commissioned as a sub-lieutenant RNVR and appointed as navigator and watchkeeper to HMS Campeador V, a vessel of the Auxiliary Patrol Service. Muir’s rank was recommended by the First Lord of the Admiralty, Winston Churchill. In June 1940 she was blown up by an enemy mine while patrolling off Portsmouth; Muir was among those killed. He was an accomplished yachtsman and his sailing memoir Messing About in Boats is another classic work, recently reissued.
