What type of transportation did Hawkeye Chingachgook and Uncas use to begin their journey?

There is no evidence of a Hawkeye Chingachgook or Uncas existing. You may be referring to the fictional characters Hawkeye, Chingachgook, and Uncas from the Leatherstocking Tales by James Fenimore Cooper. In these novels, the primary mode of transportation for the characters was by foot, though they also used canoes for travel on water and horses for overland travel.
