Why did Albrecht von Wallenstein want to capture Stralsund?

Albrecht von Wallenstein sought to capture the city of Stralsund because he intended to utilize it as a first-rate naval base.1

Following his appointment as general of the Imperial Armada and of the North and Baltic seas in 1628, Wallenstein developed a strategic vision to establish a major trading company involving the emperor, Spain, and the Hanseatic League towns. The primary objective of this initiative was to displace the Dutch and English from their dominant position in the carrying trade. Because Stralsund was a significant Baltic Sea port, its acquisition was considered essential for the success of his maritime and economic ambitions.12
