When War Stopped A Swim

Between August 28th and 29th 1943, Jenny Kammersgaard swam 75 km along Gudenåen, the longest Danish river. But the well-known 25-year-old Danish swimmer cut her scheduled swim to Randers short. She had to stop – during the morning of August 29th a state of emergency was enacted when the German forces attacked the Danish Naval Base at the Royal Dockyard (Holmen) in Copenhagen.


Whether it was before World War II, during or after the war, Kammersgaard (1918-1997) had a lengthy and prolific career:
- At the age of 17 in 1935, she swam 18 km from Snaptun to Horsens in Horsens Fjord across inner Danish waters.
- In 1935, she swam 25 km from Langeland to Korsør, after which she became sponsored by the Danish daily newspaper Politiken.
- On 7 July 1937, she attempted to swim 42 km across the Kattegat from Gniben to Grenaa, Denmark in the Danish part of the Baltic Sea, the longest any woman had swum at the time. She quit under protest after swimming 20 hours on this attempt on advice from the doctor in the escort boat at the age of 19.
- On 7 August 1937, she swam 42 km from Grenaa to Gniben, Denmark across the Kattegat in 29 hours 13 minutes after having changed medical advisor, at the age of 19. The swim distance was later inaccurately reported as 70 km, 75 km, and later 93 km (see memorial stone below that is at Gniben Strand on Sjællands Odde).
- She was celebrated in Denmark and by a song that was written in her honor: Jenny – Du er et Eventyr (or Jenny – You are an Adventure in English).
- she received a telegram of congratulation from Adolf Hitler and was used in Nazi propaganda.
- After the World War II, she helped refugees getting out of Europe through Sweden.
- Between July 27th and 29th 1938, she swam 52 km from Gedser in Denmark to the German coastal city of Warnemünde in 40 hours 30 minutes.
- Between August 9th and 11th 1939, she swam 52 km in the opposite direction from Warnemünde, Germany to Gedser, Denmark along the same route in 34 hours.
- During summer 1944, she secretly swam several times across the Øresund Strait between Denmark and Sweden.
- She was suspected her of being a courier for the Danish resistance based in Sweden.
- The Gestapo issued an arrest order for her which led to her escape to the Swedish island of Hven in Øresund where she stayed from August 1944 until the end of the World War II in May 1945.
- In August 1947, together with her boyfriend, helped Baltic refugees in Denmark go to Sweden in a small fishing boat because it was easier to emigrate to North and South America from Sweden. Kammersgaard and her boyfriend were sentenced to 40 days in prison for assisting people who were in Sweden to leave without a valid passport.
- She swam breaststroke in the 1950 Daily Mail race across the English Channel, finishing in 16 hours 27 minutes.
- She raced in the 1951 Daily Mail race across the English Channel, finishing in 15 hours 38 minutes.

- In 1959, she swam from Læsø to Frederikshavn in Denmark.
- In 1972, she swam 200m in 7 minutes 13 seconds in very cold water, reportedly “icy water”.
