The ship, which originally sailed under the English flag, was bought by the company in 1751 together with a second ship, the King of Prussia , and stationed in Emden , the company's headquarters, which had been declared a free port . While the King of Prussia started the first trip to Canton ( Chinese Empire ) in the spring of 1752 , Emden Castle was only able to leave for its first trip in October 1752 due to a dispute over competence. The proceeds from the goods on the first trip (tea, raw silk, porcelain) made hardly any profit on return at the end of May 1754, but covered the costs of the trip. At the beginning of the Seven Years' War , the company ships Prinz von Prußen and Burg von Emden lay in the home port of Emden and were dismantled. When Emden was conquered by French troops in 1757, the ships fell into the hands of the French. After the withdrawal of the French in 1758, the trading company was liquidated by the majority of the shareholders until 1765 due to the previous French occupation of Emden and the lack of profits, and the company's remaining ships were sold.
