Some cartographic skills will be needed here to assist. In The Last of the Mohicans, the garrison is located at Fort William Henry. This fort is located in Northern New York on Lake George. Located in Northeastern New York, the fort is the centre point for the action in Cooper's novel. The garrison was initially held by the English and taken over by the French in the French and Indian War. The action that takes place once the English surrender the fort is critical to Cooper's narrative.
At the conclusion of The Last of the Mohicans, Cooper has Natty Bumppo seek to reestablish connection with Chingachgook. In doing so, The Deerslayer opens. Chingachgook is located at Lake Glimmerglass, which is what we see as modern Lake Ostego. Along with Hurry Harry, Natty Bumppo sets out for Lake Glimmerglass. This is the exposition of the novel. It serves as the novel's opening because it was so dangerous in both the occupation of forces on the path as well as the length of it. Altogether, the quest from where Natty stood at the end of The Last of the Mohicans, outside Lake George, to what is now referred to as Lake Ostego where the Huron camp at Glimmerglass is located would be a journey of just over 100 miles Southwest from their location in the Northeast.
