In the early afternoon of 29 January 1915, off Walney Island, which shelters the port of Barrow-in-Furness in north-west England, the German submarine U-21 surfaced. Her crew opened fire with the deck gun on the airship shed standing on the island. It was the first foray by German submarines into the Irish Sea, which U-boats had not reached until then.

Through the English Channel

U-21 was commanded by Kapitänleutnant Otto Hersing, who in September 1914 had sunk the cruiser Pathfinder, the first warship sunk by a torpedo fired from a submarine. Around 22 January Hersing set out on a new patrol. Instead of going round the British Isles to the north, he took his boat through the Strait of Dover and the English Channel, and then headed north into the Irish Sea.

A few shots

Barrow-in-Furness was an important centre of the armaments industry. At the Vickers shipyard there warships were built, among them British submarines. On Walney Island, separated from the town by a narrow channel, stood an airship shed connected with the Vickers works. This was Hersing’s target. U-21 approached through shallow water to within a few kilometres of the shore and fired a few rounds.

The reply came quickly. On Walney there was a coastal battery manned by gunners of a Lancashire and Cheshire unit of the Royal Garrison Artillery. It opened fire at a range of about 6.5 kilometres. The exchange of fire lasted only a few minutes and, according to the available accounts, neither side scored a hit. Hersing broke off the bombardment and sailed away.

Hunting in the Irish Sea

The bombardment did no damage, but Hersing’s foray was only beginning. The next day, 30 January, U-21 sank three British steamers off the Lancashire coast, in the area of Morecambe Bay: Ben Cruachan, Linda Blanche and Kilcoan. Each time Hersing acted in accordance with the rules of prize law, allowing the crews to leave the ships before they were sunk. The same day another German submarine, U-20, torpedoed two steamers without warning off the French coast near Le Havre. The appearance of U-boats on the routes leading to the western ports of England showed that no waters around the British Isles were safe any longer. Hersing returned safely to Germany by the same route through the English Channel.
