On August 10th, 1628, the 64-gun warship Vasa left the port of Stockholm while the excited crowd were watching her departure. After a few minutes the ship encountered a strong wind and it was heeled over to the port. The gunports were open to make farewell shots and this caused the water to rush into the ship. Vasa sank after a single mile of sailing. The crew were allowed to take their families and guests along for the first part of the passage so there were around 150 people on the ship. 30 of them died onboard. Her valuable bronze cannons were salvaged.
