Tonquin was a 290-ton American merchant ship initially operated by Fanning & Coles and later by the Pacific Fur Company (PFC), a subsidiary of the American Fur Company (AFC). Its first commander was Edmund Fanning, who sailed to the Qing Empire for valuable Chinese trade goods in 1807. The vessel was outfitted for another journey to China and then was sold to German-American entrepreneur John Jacob Astor. Included within his intricate plans to assume control over portions of the lucrative North American fur trade, the ship was intended to establish and supply trading outposts on the Pacific Northwest coast. Valuable animal furs purchased and trapped in the region would then be shipped to China, where consumer demand was high for particular pelts.
