At the time of the 1911 Census, the James family were living at 48 Sea View Terrace, Swansea. William Henry is absent from the census return, but Winifred, aged 29, is recorded with her two young sons: Sidney George, aged 1, and four‑month‑old William Leslie.

Merchant Navy Service

Merchant Seamen Deaths

William Leslie served in the Merchant Navy, where he held the rank of Cook. According to Merchant Seamen Deaths, he was living at 14 Romilly Road, Cardiff at the time of his service. His role as Cook placed him at the centre of daily life aboard ship, responsible for feeding the crew during long and often dangerous wartime voyages.

The S.S. Mabriton

The S.S. Mabriton was a British cargo steamer, built in 1920 and owned by Chapman & Son, R. She operated widely across Atlantic routes during the interwar and early wartime years. On 25 September 1940, while on passage from the Tyne to Father Point (F.O.) in ballast, the vessel was torpedoed without warning and sunk. Of her 37 crew, 12 men were lost, including Cook William Leslie James.

Loss During the Battle of the Atlantic

The sinking of the Mabriton occurred during the early and ferocious phase of the Battle of the Atlantic, when German U‑boats sought to sever Britain’s supply lines. Merchant ships sailing independently or lightly escorted were especially vulnerable. The sudden attack on the Mabriton left little chance for those aboard, and the loss of life reflects the extreme dangers faced by civilian seafarers during the war.
