During a violent storm the Danish-Norwegian frigate Fredensborg was wrecked on 1 December 1768, at Tromøy, an island outside Arendal in southern Norway. The long journey in the triangular route was nearly completed when the crew of 29 men, three passengers, and two slaves managed to save their lives under very dramatic conditions. The Captain, Johan Frantzen Ferents, and the Supercargo, Christian Hoffman, saved the ship's logbook and other journals. These, together with other documents which are in the national archives in Denmark and Norway, make it possible for us to follow the course of the frigate from day to day, both during the journey and after the wreck.
The Fredensborg was built in 1752-53 by the Danish West India-Guinea Company in Copenhagen. On its first journey in the triangular trade, and during five subsequent journeys to the West Indies, it sailed under the name of Cron Prins Christian. In 1765, when the Guinea Company replaced the West India-Guinea Company, taking over the forts on the Gold Coast and all trading rights and ships, the name was changed to Fredensborg, after the Danish-Norwegian fort at Ningo. At that time Denmark-Norway owned the islands of St. Thomas, St. John, and St. Croix in the West Indies and their need for slaves was growing.
They weighed anchor in Copenhagen on 24 June 1767 with 40 men on board, and anchored in the road at their main fort Christiansborg on the Gold Coast 100 days later, on 1 October 1767. Because of an inadequate supply of slaves, the Fredensborg remained in the road for 205 days. This had a very adverse effect on the health of the crew, with 11 deaths, including that of the Captain, Espen Kiønig. One of the deceased had drowned.
