De Vries often acted as a mediatory go-between trying to keep the peace between the Lenape and New Netherlands Director-General William Kieft. De Vries famously tried to prevent Kieft from launching the Pavonia Massacre and Massacre at Corlears Hook, which set off the two-year-long Kieft's War. After the massacres, De Vries was influential in bringing the Hackensack Indians sachem Oratam and also the Canarsee sachem Penhawitz to negotiate a truce, which did not hold in the face of Kieft's aggressive policies.[7] De Vries became a leading figure in the popular uprising against Kieft in the Dutch colony which ultimately led to the Director-General's dismissal and recall for trial. Disenchanted by the New Netherlanders' treatment of the indigenous population, he left his farm at Vriessendael in October 1643 in the wake of the Pavonia Massacre, and returned to Holland.[1]
