Magellan set sail in 1519 with his fleet of five three-master ships. The voyage went into the unknown, his goal: to find a western route to the Spice Islands. Three years later only one of the five ships returned, only 18 men had survived the voyage. Nevertheless, the voyage was an epochal triumph: Magellan had not only found a passage to the Pacific Ocean, but for the first time the world had been circumnavigated. This was the practical proof for the theory of the astronomer Copernicus, who had claimed: The earth is round! - Even today, the history of circumnavigating the world is still full of excitement: Rollo Gebhard, who sailed around the world twice with the cruiser Solveig III with one hand, tells how adventurous the voyage on the vastness of the oceans is.
