In 1622, the Dutch, based in Batavia, were seeking to establish a stronger presence in East Asia. A fleet of six ships led by Cornelis Reijersen attempted to capture Macau to disrupt the Portuguese's profitable Macau-Nagasaki route. However, despite outnumbering the defenders, Reijersen's fleet was defeated and repelled. Frustrated, they turned to the Pescadores (modern day Penghu) to set up a base and coerce the Chinese into trading with them.
