Why did the dutch leave delaware and who took over?

The Delaware watershed was claimed by the English based on the explorations of John Cabot in 1497, Captain John Smith, and others, and was given the name held as a title by Thomas West, 3rd Baron De La Warr, the governor of Virginia from 1610 until 1618. At that time the area was considered to be part of the Virginia colony.However, the Dutch thought they also had a claim, based on the 1609 explorations of Henry Hudson, and under the auspices of the Dutch West India Company were the first Europeans to actually occupy the land. They established trading-posts: Fort Wilhelmus in 1624 at "Hooghe Eyland" (High Island), now Burlington Island, opposite Burlington, New Jersey; Fort Nassau, near Gloucester City, New Jersey, in 1626; and at Zwaanendael, now Lewes, Delaware, in 1631.[2] Peter Minuit was the Dutch Director-General of New Netherland during this period and probably spent some time at the Burlington Island post, thereby familiarizing himself with the region.
