Kane then organized and headed the Second Grinnell expedition which sailed from New York on May 31, 1853, and wintered in Rensselaer Bay. Though suffering from scurvy, and at times near death, he pushed on and charted the coasts of Smith Sound and the Kane Basin, penetrating farther north than any other explorer had done up to that time. At Cape Constitution he discovered the ice-free Kennedy Channel, later followed by Isaac Israel Hayes, Charles Francis Hall, Augustus Greely, and Robert E. Peary in turn as they drove toward the North Pole.
