Sweden in World War II - across borders


Swedish border control and defence

When Sweden began to rearm in the late 1930s, not much was spent on anti-aircraft guns. The armed forces were willing to man anti-aircraft guns, but the purchase of the guns had to be made with civilian funding. In April 1938 the rules for the use of such gift-guns were ready. [s49]

(One of Sweden's three large armoured warships, "Sverige" (1915), had also been funded with civilian funding - but that was due to political disagreement.) [s62]

The German attack on Poland in 1939 had the effect that the armed forces placed anti-aircraft guns at important industrial areas. [s49]

One example of areas where there were no military plans for anti-aircraft defence is the town Falkenberg, on Sweden's west coast south of Göteborg, with 6,000 inhabitants at the time. The military said that four 20 mm automatic guns (in two groups) could be suitable for a town with the size as Falkenberg. The fundraising began on 6 February 1940, with a second fundraising campaign from 2 March. The second time the names of the contributors were published in the local newspaper, with the sum they had given. On 11 September 1940 a letter was sent to the Swedish king about the gift of two guns with equipment and spare parts (the town people didn't manage to collect more money). A contract with Bofors was signed the same day, 11 September 1940, including 16 magazines with 25 rounds each. On 10 November 1942 the guns were shipped from Bofors via railway, and the test shooting took place on 14 February 1943. The test included diving planes from the Swedish air force. On 22 June 1944 the anti-aircraft gun was used for real for the first time, this time too against a plane from the Swedish air force (which wasn't hit). There was no radar or searchlights in Falkenberg. The guns were used often, especially when large Allied bomber groups flew southwards to Germany along the Swedish coast. [s49]

At the time the fund-raising went on, three plutoons with 79 men were formed for guard duty along bridges and a part of the beach. Each soldiers military equipment was a belt for ammunition, a hat and a jacket. Later they also got rifles. [s49]

Gas masks were handed out free, but not so many. One family of four received one gas mask. [s49]


Swedish mineWhen WWII began the Swedish navy had an operative force of about 50 ships. A few of the ships had test radar equipment. They were among others used to escort ship convoys in Swedish waters, where the lighthouses were out of use. Merchant ships were given orders about narrow safe passages, when to blind the lights, et cetera. There had also been incidents when depth charges or anti-aircraft guns had been used. [s52]

In May 1940 a Swedish minefield was laid in Swedish waters near the city Varberg. [s63]

The Swedish navy laid a minefield in Swedish waters south of the island Öland in the summer of 1941, as Germany wanted. This minefield worked as an extension to one of the German minefields in the Baltid Sea, laid when Germany attacked the Soviet Union on 22 June. [s63]

On 9 July 1941 3 German support cruisers sailed into the Swedish minefield, despite attempts by a Swedish naval vessel to warn them, and sank. [s63]


In 1936-1942 Sweden built 9 submarines of the type Sjölejonet. [s52]


After a cold winter and spring in 1942, with plenty of sea ice, the Swedish coastal fleet was operative again at the end of April. The coastal fleet consisted of 3 large armoured ships, 9 destroyers, 8 submarines and 4 smaller warships. [s59]

For escort duties in Swedish waters the fleet could not support more than 4-6 destroyers and the smaller warships. Even convoys with more than 20 ships seldom had more than 2 navy escort ships. [s59]

During transit of German troops in Swedish waters, there were Swedish guards on board the German ships [s68]. (My note: at least sometimes.)

Swedish minesweeper M20The Swedish minesweeper M 20 was in service for minesweeping and patrol in various areas on Sweden's west coast during WWII, among others at the Swedish island Ven between Denmark and Sweden. In June-July 1944 she often was anchored, to save fuel. (She was built at the Neglingevarvet in Stockholm in 1941, in a series of 12 built at 12 (10? my note) warfts and delivered within one year. She was in service until December 2004, and rebuilt a couple of times. In June 2005 she became a museal ship. Today she looks about the same as when she was new.) [s66]

Sweden's old open seaplanes, type S-5 Hansa, were effective when looking for submarines. [s59]

The Swedish escort ships and reconnaissance planes forced submarines to attack in submerged position, which slowed down the submarines and made it more difficult to aim correctly. Now and then destroyers made nightly patrols to disturb or maybe capture submarines on the surface recharging their batteries. [s59]


In 1942 some of the Swedish destroyers, normally with light grey paint, got camouflage paint instead. The normally white identification numbers were also painted over and not visible, and on a few destroyers also the white 'neutrality ribbons' were painted over. [s70]


From late May (1942? - didn't note the year when I wrote this text fragment ...) Swedish merchant ships in the "lejdtrafiken" began to get anti-mine devices. 75 ships were equipped with them, but seemingly none of them rendered mines harmless. [s64]

At least 11 mines were made harmless by the anti-mine devices. [s65]


The escort duty was one of the tasks for the Swedish navy. The need grew after the German attack on the Soviet Union, when Soviet Union submarines began to attack ships that sailed between Sweden and Germany in the Baltic Sea. In June-October 1942 some 9,000 ship sailings were escorted in convoys, of which 2 were sunk. (3 other sunk ships were not in convoys at the time of the torpedo attacks.) Totally 17,796 ship sailings got escort during the war. [s71]


Sweden sank two Swedish tankers outside Göteborg harbour in late March 1944, and made other preparations to meet a German attack. Sweden had learnt that Germany knew about the Finnish peace feelers with the Soviet Union, and feared that a German counter move could involve Sweden. [s64]

Sweden laid a minefield along the west coast after the Allied invasion in Normandie on 6 June 1944, and sharpened the guard. Naval battles were expected in the area between Allied and German forces. The minefield forced ships that sailed between Germany and Norway to use international waters, where British bombers attacked them. [s64]
