By the time Smith left Virginia in 1609, the fragile peace between colonists and Algonquians was already beginning to fray. Soon conflict led to the First Anglo-Powhatan War, and further English expansion beyond Jamestown and into Powhatan's territory. The English effectively destroyed two subtribes, the Kecoughtan and the Paspahegh, at the beginning of this war. Powhatan sent Nemattanew to operate against the English on the upper James River, though they held out at Henricus. With the capture of Pocahontas by Captain Samuel Argall in 1613, Powhatan sued for peace. It came about after her alliance in marriage on April 5, 1614 to John Rolfe, a leading tobacco planter. John Rolfe was one of Pocahontas’s many Jamestown teachers before their marriage; he instructed her in matters of the new culture she was being assimilated into, and he also taught her all about Christianity. According to various accounts, Pocahontas and John Rolfe did, in fact, fall in love with each other—it was a consensual relationship. This might, at least in part, explain Pocahontas’s apparent willingness to assimilate, convert to Christianity and remain with the English: she wanted to be with Rolfe. Rolfe's longtime friend, Reverend Richard Buck presided the wedding. Prior to the wedding, Reverend Alexander Whitaker converted Pocahontas and renamed her "Rebecca" at her baptism.
