Fort Metal Cross a trading post for the slave supply was crucial to supply labor for what country
Atlantic slave trade The Atlantic slave trade or transatlantic slave trade involved the transportation by slave traders of enslaved African people, mainly from Africa to the Americas, and then their sale there. The slave trade used mainly the triangular trade route and its Middle Passage, and existed from the 16th to the 19th centuries. The vast majority of those who were enslaved and transported in the transatlantic slave trade were Africans from central and western Africa, who had been sold by other West Africans to Western European slave traders (with a small number being captured directly by the slave traders in coastal raids), who brought them to the Americas. The South Atlantic and Caribbean economies especially were dependent on the supply of secure labour for the production of commodity crops, making goods and clothing to sell in Europe. This was crucial to those western European countries which, in the late 17th and 18th centuries, were vying with each other to create overseas empires.
Fort Cowlitz Fort Cowlitz or Cowlitz Farm was an agricultural operation by the British Puget Sound Agricultural Company (PSAC), a subsidiary of the Hudson's Bay Company (HBC). It was located on the Cowlitz plains, adjacent to the west bank of the Cowlitz River and several miles northeast of modern Toledo, Washington. The farm was begun during spring of 1839, and its produce soon supplied HBC posts in New Caledonia and Columbia Departments. In the RAC-HBC Agreement, the Russian-American Company received at Novo-Arkhangelsk grain and dairy products from the PSAC along with manufactured goods. Fort Cowlitz produced most of the Company wheat quotas, and its fellow PSAC station Fort Nisqually tended most of the sheep and cattle flocks. By the expiration of the agreement in 1850, Cowlitz Farm wasn't able to meet Russian supply demands.
