On August 27, 1664, four English frigates led by Richard Nicolls sailed into New Amsterdam's harbor and demanded New Netherland's surrender. They met no resistance because numerous citizens' requests had gone unheeded for protection by a suitable Dutch garrison against "the deplorable and tragic massacres" by the Indians. That lack of adequate fortification, ammunition, and manpower made New Amsterdam defenseless, and the West India Company had been indifferent to previous pleas for reinforcement of men and ships against "the continual troubles, threats, encroachments and invasions of the English neighbors". Stuyvesant negotiated successfully for good terms from his "too powerful enemies". In the Articles of Transfer, he and his council secured the principle of religious tolerance in Article VIII, which assured that New Netherlanders "shall keep and enjoy the liberty of their consciences in religion" under English rule. The Articles were largely observed in New Amsterdam and the Hudson River Valley, but were violated along the Delaware River, where Colonel Sir Robert Carr expropriated property for his own use and sold Dutch prisoners of war into slavery. Nicolls eventually forced Carr to return some of the expropriated property. In addition, a Mennonite settlement led by Pieter Corneliszoon Plockhoy near Lewes, Delaware was destroyed. The 1667 Treaty of Breda ended the Second Anglo-Dutch War; the Dutch did not press their claims on New Netherland, and the "status quo" was maintained, with the Dutch occupying Suriname and the nutmeg island of Run.
