provide maps for Arnold. Goodwin, who was known to have Loyalist sympathies, provided maps that were inaccurate in the routes, distances and other important features they described. On September 2, Washington received a letter from General Schuyler in reply to his August 20 message. Schuyler agreed with the suggested plan, and Washington and Arnold immediately began to raise troops and place orders for supplies. Recruitment and preparations for departure Because there had been little direct action at Boston after the Battle of Bunker Hill in June, many units stationed in the American camps besieging the town were bored with garrison life and eager for action. Arnold selected a force of 750 men from the large number who expressed interest in the proposed expedition. Most of these were divided into two battalions: one commanded by Lieutenant Colonel Roger Enos and the other by Lieutenant Colonel Christopher Greene. The rest were placed in a third battalion under Daniel Morgan that included three companies—250 men—of Continental riflemen from Virginia and the Pennsylvania Rifle Regiment. These frontiersmen, from the Virginia and Pennsylvania wilderness, were better suited to wilderness combat than to a siege, and had been causing trouble since arriving outside Boston. The entire force numbered about 1,100. Among the volunteers were other men who rose to later prominence during and after the war, including Aaron Burr, Return J.

Washington and Arnold were concerned about Indian support for (or opposition to) the effort, as well as the reception Arnold's forces might receive from the Canadians once they arrived near the Saint Lawrence River. On August 30, Washington wrote to General Schuyler of a meeting he held with an Abenaki chief, "[The chief] says the Indians of Canada in general, and also the French, are greatly in our favor, and determined not to act against us." Four Abenakis accompanied the expedition as scouts and guides.

He asked Tracy to acquire sufficient shipping to transport the expedition to Maine without drawing the attention of Royal Navy ships patrolling the area. The sea voyage was viewed by both Arnold and Washington as the most dangerous part of the expedition, because British patrols were highly effective at interfering with
