George Bernard Denis Murphy – Mercantile Marine - S.S. Excellence Pleske

Sailor George Bernard Denis Murphy – Mercantile Marine, S.S. Excellence Pleske

Early Life and Family Background

Birth and Parentage

George Bernard Denis Murphy was one of Swansea’s youngest mercantile marine casualties of the First World War. Born in 1901 in Swansea, he was the son of Henry Joseph Murphy and Ellen Winter. By the time of George’s death in 1918, the family were living at 10 Moira Street, Adamstown, Cardiff.

S.S. Excellence Pleske

The S.S. Excellence Pleske was a merchant steamship operating during a period of intense German submarine activity. Merchant ships like the Excellence Pleske were essential to Britain’s wartime supply chain but were often unarmed or poorly protected, leaving them vulnerable to U-boat attacks.

George served aboard the vessel as a Sailor, undertaking general deck duties essential to the operation of the ship. On 31st March 1918, the Excellence Pleske was torpedoed and sunk by the German submarine UB-57. The attack occurred during the height of Germany’s 1918 unrestricted submarine warfare campaign, which targeted merchant shipping around the British Isles.

George Murphy was among those who lost their lives when the ship went down. At just 17 years old, he was one of Swansea’s youngest maritime casualties of the Great War.

UB-57

The UB-57 was a Type UB III submarine, one of Germany’s most effective coastal torpedo-attack U-boats. Commissioned in 1917, she was commended for part of her service by the highly successful U-boat ace Oberleutnant zur See Johannes Lohs.

The UB III class was designed for aggressive operations in the shallow, busy waters of the English Channel and North Sea, carrying 10 torpedoes and a deck gun. These submarines were responsible for significant losses among merchant vessels, striking quickly and disappearing into coastal waters.

UB-57 conducted several successful patrols, sinking numerous Allied ships. One of her victims was the S.S. Excellence Pleske, torpedoed on 31st March 1918, with the loss of George Bernard Denis Murphy.

UB-57 herself was lost later that year, sinking with all hands in the Strait of Dover on 14th August 1918, believed to have struck a British mine while returning from patrol.

Legacy

Although little is known about George’s personal life, his sacrifice reflects the courage of the many young men who served in the Mercantile Marine. At just 17, he faced the same deadly dangers as seasoned adult mariners—submarines, mines, and hazardous sea conditions—and lost his life while helping to maintain Britain’s vital wartime shipping routes.

George’s story stands as a reminder that the Merchant Service relied heavily on youths, many of whom undertook adult responsibilities aboard ship long before reaching adulthood. His service and sacrifice form part of Swansea’s maritime heritage and the wider story of the young men who kept Britain supplied during the war.
