Frigate Flensborg

The frigate and man-of-war Flensborg, or Flensburg, was a Danish East Indiaman sent on 2 December 1629 to Tranquebar as the third cargo to India. However, it was blown up by the Portuguese off the Cape of Good Hope in 1630.

History
Flensburg was launched in 1625 and commanded by Thimand Clausen. In the following year, after being loaned out to the Danish East India Company, she went on a voyage to Ireland with spare parts to the Perlen, one of the company's East Indiamen, which was nearly wrecked on its home voyage to Denmark.

In 1629, Christian IV of Denmark concluded peace with Ferdinand II, which meant he could thus regain his interests for the Indian trade. Subsequently, the Flensburg was sent to Tranquebar together with Falken and Fortuna. She was under the command of captain Six Jacobsen. However, upon reaching the Cape of Good Hope, the Flensborg was attacked by Portuguese vessels, which resulted in it catching fire and exploding. Most of the crew was killed in the explosion, and the rest were imprisoned by the Portuguese.

The Fortuna reached Tranquebar on 29 September 1631.
