In September 1776 a military road was built from east of Rutland, Vermont, through Hubbardton and on to Mount Independence in Orwell. The Mount Independence-Hubbardton Military Road has a number of friends who have created this website, which includes a PDF of the 1968 book, The Mount Independence-Hubbardton 1776 Military Road, by Joseph Wheeler.

From 1609 through 1814, Lake Champlain and Lake George, together were the scene of contests and conflicts the likes of which had seldom been seen in civilized lands. During the brief periods of peace, these pathways through the wilderness were utilized by settlers as the only routes through the mountain forests to their new homes. It was only after the great American Civil War that the lake became unimportant to military planners. When finally the waterways lost their strategic military value due to settlement and technological advances, the corridors became important avenues of commerce and recreation. (Millard, James P.)
