John George Edward Harris – Mercantile Marine - S.S. Llwyngwair

Second Engineer John George Edward Harris – Mercantile Marine, S.S. Llwyngwair

Background and Family Life

John George Edward Harris was born in 1892, in Wellington, New Zealand, the son of George Thomas Harris and Margaret Mabel Harris. Although born overseas, John’s life and career later became closely connected with Swansea, where he established his home.

In 1912, he married Gwenllian Davies, and the couple settled at 32 Percy Street, Swansea. Like many men from the town’s strong maritime community, John pursued a career at sea, joining the Mercantile Marine as a marine engineer — a demanding profession requiring technical expertise, long hours, and courage.

Service and Loss

During the First World War, John Harris served as Second Engineer aboard the S.S. Llwyngwair, a Swansea-owned merchant steamship operating in British coastal waters. His duties included overseeing the ship’s propulsion systems, boilers, and machinery — the vital heart of the vessel.

On 26th April 1918, while sailing along the north-east coast of England, the Llwyngwair was torpedoed and sunk without warning by a German submarine. The ship went down rapidly, and Second Engineer John George Edward Harris, aged just 26, was among those who lost their lives.

The S.S. Llwyngwair

The S.S. Llwyngwair was a British merchant steamer of approximately 1,304 gross register tons, built in 1913 by the Antwerp Engineering Company Ltd. She was owned by Harries Bros & Co. of Swansea and named after the Llwyngwair estate in Pembrokeshire.

On 26th April 1918, the vessel was sailing from Middlesbrough to London when she was torpedoed and sunk by the German submarine SM UC-64, approximately five nautical miles south-southeast of Seaham Harbour, County Durham. Several crew members were killed, including John Harris of Swansea.

The loss of the Llwyngwair illustrates the ever-present danger faced by merchant ships even close to home waters, as Germany’s campaign of unrestricted submarine warfare brought the front line of conflict to Britain’s coasts.

The German Submarine SM UC-64

The SM UC-64 was a Type UC II minelaying submarine of the Imperial German Navy, commissioned on 22nd February 1917. Measuring 51.85 metres in length and displacing about 422 tons surfaced and 504 tons submerged, she carried a complement of 26 men.

Armed with six mine tubes carrying up to 18 mines, three torpedo tubes with seven torpedoes, and an 8.8 cm deck gun, UC-64 was designed to strike merchant shipping both by laying mines along key routes and through direct torpedo attacks.

Operating primarily in the North Sea and English Channel, UC-64 conducted 15 patrols and was credited with sinking 26 ships before meeting her own end. On 20th June 1918, she was mined and sunk with all hands in the Dover Strait, ending her career as one of the many U-boats that brought heavy losses to Britain’s merchant fleet.

Her attack on the Llwyngwair is one of many examples of how Germany’s U-boat campaign endangered the men of the Mercantile Marine, who faced the same hazards as the Royal Navy but with far fewer defences.

Second Engineer John George Edward Harris is commemorated on the Tower Hill Memorial, London — the national monument dedicated to those of the Merchant Navy and Fishing Fleets who died at sea during both World Wars and have no known grave but the ocean.

Legacy

Although his life was brief, John Harris exemplifies the courage and dedication of Swansea’s maritime community. His story — spanning from New Zealand to South Wales and ending in the cold waters off Durham — reflects the global reach and sacrifice of the Mercantile Marine during the First World War.

His name, carved on the Tower Hill Memorial, ensures that his service will never be forgotten
