Burgoyne's army was beset by transport difficulties before it left Quebec, something that apparently neither Burgoyne nor Carleton anticipated. As the expedition expected to travel mainly over water, there were few wagons, horses, and other draft animals available to move the large amount of equipment and supplies on the land portions of the route. Only in early June did Carleton issue orders to procure carts sufficient to move the army. Consequently, the carts were poorly constructed of green wood, and the teams were driven by civilians who were at a higher risk of desertion.
