Carpenter John Brustad Nielsen – Mercantile Marine, S.S. Tangistan

Early Life and Background

Birth and Family Origins

John Brustad Nielsen was born in 1856 in Norway, the son of Zachariah and Bertha Nielsen. Like many Scandinavian mariners of the late 19th century, he eventually settled in Swansea, where the busy docks and expanding maritime industries offered steady work to skilled seafarers.

Marriage and Early Life in Swansea

In June 1886, John married Mary Elizabeth Powell at St. Mary’s Church, Swansea. Their marriage certificate records that both were living in St. Thomas at the time, and that John was employed as a Sail Maker, a skilled craft closely linked to the port’s shipping trade.

Scandinavian Mariners in Swansea

During the late 19th and early 20th centuries, Swansea attracted a small but notable community of Scandinavian mariners, particularly from Norway, Sweden, and Denmark. Drawn by coal exports, ship repairs, and opportunities in the docks, many Scandinavian sailors settled permanently in the town after years at sea. They were employed in skilled roles such as sail making, ship carpentry, and dock trades, and often lived in the maritime districts of St. Thomas, St. John’s, and the harbour area.

Some arrived aboard Scandinavian timber ships; others served on British merchant vessels and chose to make Swansea their home through marriage or long-term residence. By the outbreak of the First World War, numerous Scandinavian-born men were serving in the British Mercantile Marine, becoming part of the town’s diverse maritime workforce.
John Nielsen’s life and service reflect the important contribution this community made to Swansea’s seafaring heritage.

1901 Census

The 1901 Census records the Nielsen family living at 22 Morris Lane, St. Thomas, Swansea. John, aged 44, was recorded as not a British subject and working as a Ship’s Carpenter. His wife Mary, originally from Haverfordwest, was 43 years old. Their children living at home were:
Bertha E. (13), Alpha M. (12), Thomas J. (10), Gilbert C. (8), Wilfred (6), Annie V. (4), and Brinley P., aged 1.

1911 Census

By 1911, the family had moved to 34 Morris Lane, still in St. Thomas. John, then 57, remained employed as a Carpenter, recorded as Norwegian-born but resident in Britain. Mary was 53, and several children remained at home:
Thomas John, 21, a Locomotive Fireman; Gilbert, 16, a Railway Checker; Wilfred, 16, a Railway Number Taker; and the younger sons Brinley (11) and Grenville (8), both in school.

S.S. Tangistan

John returned to sea in later years, serving as a Carpenter aboard the S.S. Tangistan, a steel-hulled steam cargo ship of 3,738 gross tons. Built in 1906 by William Gray & Co. Ltd., the vessel was originally operated by the Anglo-Algerian Steamship Company before passing to Strick Line Ltd.

On her final voyage in March 1915, the Tangistan was carrying a cargo of iron ore. While sailing off Flamborough Head in the North Sea, she was destroyed by a sudden and devastating explosion on 9th March 1915. The loss is believed to have been caused by a mine laid by German forces, a significant threat to merchant ships in the early years of the war. Of her entire crew, only one man survived. Among those lost was Carpenter John Brustad Nielsen.

U-35

Although the Tangistan was almost certainly sunk by a mine, she was operating in waters patrolled and mined by German submarines, most notably the highly successful U-35. This Type U 31 ocean-going submarine, commissioned in 1914, became the most successful U-boat of the First World War, sinking ships across the Mediterranean and beyond. Commanded by Lothar von Arnauld de la Perière, U-35 helped establish the deadly environment in which merchant vessels like the Tangistan operated, through mine warfare and aggressive submarine patrols.

The danger from German minelaying and U-boat activity made coastal and North Sea routes among the most hazardous in the world, contributing directly to the loss of ships such as the Tangistan.

Legacy 

John Nielsen’s story is representative of the many foreign-born mariners who settled in Swansea and contributed significantly to its maritime industries. A skilled Sail Maker and Ship’s Carpenter, he spent decades working in the town’s seafaring trades before giving his life in service to the Merchant Navy during the First World War. His sacrifice left behind a large family and forms part of Swansea’s broader maritime heritage, reflecting the essential role played by working-class seafarers during times of peace and conflict.
