Peter Minuit, who had construed a deed for Manhattan (and was soon after dismissed as director), knew that the Dutch would be unable to defend the southern flank of their North American territory and had not signed treaties with or purchased land from the Minquas. After gaining the support from the Queen of Sweden, he chose the southern banks of the Delaware Bay to establish a colony there, which he did in 1638, calling it Fort Christina, New Sweden. As expected, the government at New Amsterdam took no other action than to protest. Other settlements sprang up as colony grew, mostly populated by Swedes, Finns, Germans, and Dutch. In 1651, Fort Nassau was dismantled and relocated in an attempt to disrupt trade and reassert control, receiving the name Fort Casimir. Fort Beversreede was built in the same year, but was short-lived. In 1655, Stuyvesant led a military expedition and regained control of the region, calling its main town "New Amstel" ("Nieuw-Amstel"). During this expedition, some villages and plantations at the Manhattans (Pavonia and Staten Island) were attacked in an incident that is known as the Peach Tree War. These raids are sometimes considered revenge for the murder of an Indian girl attempting to pluck a peach, though it was likely that they were a retaliation for the attacks at New Sweden.
