Denis Gallivan – Merchant Navy, S.S. Fort Gibraltar

Fireman Denis Gallivan – Merchant Navy, S.S. Fort Gibraltar

Early Life

Denis Gallivan was born in 1892 in Swansea, the son of Denis Gallivan and Bridget Hannen, who had married in 1884 in Swansea.

1911 Census

By the time of the 1911 Census, the Gallivan family were living at 20 Anne Street, Greenhill, Swansea, a home that would remain their address for many years. Denis senior, then 48, was employed as an Alkali Worker, while his wife Bridget, aged 49 and originally from Merthyr, managed the household. Three children were living at home: Denis (19), James (14)—working as a Baker’s Errand Boy—and Bridget (16), who was employed as a General Servant.

1921 Census

A decade later, the 1921 Census shows the family still residing at 20 Anne Street. Denis senior, now 60, was working as a General Labourer, and Bridget, also 60, continued to keep the home. Their children were still living with them: Denis (29), now working as a Ship’s Fireman; Bridget (26); and James (24), employed as a Labourer at the National Oil Refiners. This long‑established household formed the centre of Denis’s life before and during his maritime career.

Service in the Merchant Navy

Denis followed a seafaring path and served with the Merchant Navy, working as a Fireman—a demanding and hazardous role deep in the ship’s stokehold, responsible for feeding the boilers and maintaining steam pressure. His recorded address at the time of his death remained the family home at 20 Anne Street, Greenhill.

He served aboard the S.S. Fort Gibraltar, one of the “Fort” class merchant ships built to support the Allied war effort during the Second World War.

Death at Philippeville, Algeria – 24^th May 1943

Merchant Seamen Deaths

According to the Merchant Seamen Deaths register, Fireman Denis Gallivan drowned at Philippeville, Algeria, on 24^th May 1943 while serving aboard the S.S. Fort Gibraltar. Although the precise circumstances of his death are not fully detailed in surviving records, it occurred during wartime operations in the Mediterranean, a region where Allied merchant ships faced constant danger from submarines, mines, and air attack.

His death reflects the wider sacrifice made by Merchant Navy personnel, whose work was essential to sustaining Allied forces across multiple theatres of war.
