Fort Metal Cross a trading post for the slave supply was crucial to supply labor for what country
Fort Metal Cross Fort Metal Cross, originally Fort Dixcove, is a military structure in Dixcove, Ghana. It was built commencing in 1683 by the English Royal African Company as a trading post for the gold and the slave trade, though construction didn't finish until 1698 due to ongoing hostilities with the local people. Brandenburg-Prussia started building Fort Groß Friedrichsburg about 15 km west of Dixcove in 1683, (now Princes Town) in the colony of Brandenburger Gold Coast but it was not completed until the 1690s.
Fort Lisa (North Dakota) The first Fort Lisa (1810-1812), also known as the Fort Manuel Lisa Trading Post, Fort Manuel or Fort Mandan, was started by the notable fur trader Manuel Lisa of the Missouri Fur Company in 1809. This fort was likely where Sacagawea died; she had been the guide for the Lewis and Clark Expedition. Fort Lisa superseded Fort Raymond as the uppermost post of the Missouri Fur Company on the Missouri River. In 1812 Lisa built a replacement fort downriver near present-day North Omaha, Nebraska, which he also named Fort Lisa.
