In March 1617, the Rolfe family was prepared to come back to Virginia. After traveling down the Thames River, Pocahontas, seriously ill, had to be taken onto dry land. In the town of Gravesend, Pocahontas died of an unspecified illness. Several historians consider she grieved from an upper respiratory ailment, such as pneumonia, while others think she could have died from some form of dysentery. Pocahontas, about twenty-one, was buried at St. George's Church on March 21, 1617. John Rolfe returned to Virginia, but left the young ill Thomas with relatives in England. Within a year, Powhatan died. The "Peace of Pocahontas" began to gradually unravel. Life for her people would never be the same.
