James Muir was born on 29th October 1889 in the hamlet of Burness on the remote Orkney island of Sanday. The youngest of three children, he was the only son to agricultural labourer Alexander Muir and his wife, Ann.
Little information remains about James’ early life. He seems to have found work at sea, as, when war broke out, he enlisted in the Royal Naval Reserve. His service records show that he was 5ft 8in (1.72m) tall, with brown eyes and a fresh complexion.
Deck Hand Muir initially served on the depot ship HMS Zaria, before bring transferred to the cruiser HMS Brilliant. By the spring of 1917, he was stationed at HMS Pembroke, the Royal Naval Dockyard in Chatham, Kent.
James was admitted to the town’s Royal Naval Hospital, suffering from fibroid phthisis, a wasting disease of the lungs. Formally discharged from the Royal Naval Reserve on medical grounds on 28th June 1917, his condition was to worsen, and he passed from the heart condition pericarditis on 16th July. He was 27 years of age.
James Muir passed away 560 miles (900km) from home: he was laid to rest in the naval section of Woodlands Cemetery, Gillingham, Kent, not far from the dockyard that had been his home.
