In September 1775, early in the American Revolutionary War, Colonel Benedict Arnold led a force of 1,100 Continental Army troops on an expedition from Cambridge in the Province of Massachusetts Bay to the gates of Quebec City. The expedition was part of a two-pronged invasion of the British Province of Quebec, and passed through the wilderness of what is now Maine. The other expedition invaded Quebec from Lake Champlain, led by Richard Montgomery.
Unanticipated problems beset the expedition as soon as it left the last significant colonial outposts in Maine. The portages up the Kennebec River proved grueling, and the boats frequently leaked, ruining gunpowder and spoiling food supplies. More than a third of the men turned back before reaching the height of land between the Kennebec and Chaudière rivers. The areas on either side of the height of land were swampy tangles of lakes and streams, and the traversal was made more difficult by bad weather and inaccurate maps. Many of the troops lacked experience handling boats in white water, which led to the destruction of more boats and supplies in the descent to the Saint Lawrence River via the fast-flowing Chaudière.
By the time that Arnold reached the settlements above the Saint Lawrence River in November, his force was reduced to 600 starving men. They had traveled about through poorly charted wilderness, twice the distance that they had expected to cover. Arnold's troops crossed the Saint Lawrence on November 13 and 14, assisted by the local French-speaking Canadiens, and attempted to put Quebec City under siege. Failing in this, they withdrew to Point-aux-Trembles until Montgomery arrived to lead an unsuccessful attack on the city. Arnold was rewarded for his effort in leading the expedition with a promotion to brigadier general.
Arnold's route through northern Maine has been listed on the National Register of Historic Places as the Arnold Trail to Quebec, and some geographic features in the area bear names of expedition participants.
Background On May 10, 1775, shortly after the American Revolutionary War began, Benedict Arnold and Ethan Allen led an expedition that captured Fort Ticonderoga on Lake Champlain in the British Province of New York.Desjardin (2006), p. 9 Allen and Arnold were aware that Quebec was lightly defended; there were only about 600 regular troops in the entire province.Stanley (1973), p. 29 Arnold, who had done business in the province before the war,Desjardin (2006), p. 8 also had intelligence that the French-speaking Canadiens would be favorably disposed toward a colonial force.Desjardin (2006), p. 11
Arnold and Allen each made arguments to the Second Continental Congress that Quebec could and should be taken from the British, pointing out that the British could use Quebec as a staging area for attacks down Lake Champlain and into the Hudson River valley. Congress did not want to alarm the people of Quebec, and rejected these arguments.Smith (1907), Volume 1, p. 237 In July, amid concerns that the British might use Quebec as a base for military movements into New York, they changed their position, and authorized an invasion of Quebec via Lake Champlain, assigning the task to Major General Philip Schuyler of New York.Smith (1907), Volume 1, pp. 241–242
Planning
Arnold, who had hoped to lead the invasion, decided to pursue a different approach to Quebec. He went to Cambridge, Massachusetts in early August, and approached George Washington, Commander-in-Chief of the Continental Army, with the idea of a second eastern invasion force aimed at Quebec City.Smith (1907), Volume 1, pp. 398–399 Washington approved of the idea in principle, but sent a message to General Schuyler on August 20 to ensure his support of the endeavor, since the two forces would need to coordinate their efforts.Martin (1997), pp. 108–109
Arnold's plan called for the expedition to sail from Newburyport, Massachusetts along the coast and then up the Kennebec River to Fort Western (now Augusta, Maine). From there, they would use shallow-draft river boats called bateaux to continue up the Kennebec River, cross the height of land to Lake Mégantic, and descend the Chaudière River to Quebec. Arnold expected to cover the from Fort Western to Quebec in 20 days,Martin (1997), p. 121 despite the fact that little was known about the route.Randall (1990), pp. 151–152 Arnold had acquired a map (copy pictured at right) and journal made by British military engineer John Montresor in 1760 and 1761, but Montresor's descriptions of the route were not very detailed, and Arnold did not know that the map contained some inaccuracies or that some details had been deliberately removed or obscured.Smith (1903), p. 17
Washington introduced Arnold to Reuben Colburn, a boat builder from Gardinerstown, Maine, who was in Cambridge at the time. Colburn offered his services, and Arnold requested detailed information about the route, including potential British naval threats, Indian sentiment, useful supply opportunities, and an estimate of how long it would take to construct bateaux sufficient for the contemplated force. Colburn left for Maine on August 21 to fulfill these requests.Desjardin (2006), p. 13 Colburn asked Samuel Goodwin, the local surveyor in Gardinerston, to 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.Randall (1990), p. 152
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.Randall (1990), pp. 147–150
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.Smith (1907), Volume 1, pp. 506–507 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.Desjardin (2006), pp. 16–17 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.Randall (1990), p. 150 The entire force numbered about 1,100.Smith (1903), pp. 22, 57 Among the volunteers were other men who rose to later prominence during and after the war, including Aaron Burr, Return J. Meigs, Henry Dearborn, and John Joseph Henry.Desjardin (2006), pp. 199–203
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."Desjardin (2006), p. 14 Four Abenakis accompanied the expedition as scouts and guides.Martin (1997), p. 116
Cambridge to Fort Western
On September 2, as soon as General Schuyler's agreement with the expedition was known, Arnold wrote a letter to Nathaniel Tracy, a merchant of his acquaintance in Newburyport. 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 colonial shipping at the time.Randall (1990), p. 151
The expedition began its departure from Cambridge on September 11, marching to Newburyport. The first units to leave were composed largely of men from that area, to whom Arnold had given extra time so that they would be able to see their families once more before the expedition left Newburyport. The last troops marched off on September 13; Arnold rode from Cambridge to Newburyport on September 15 after making final purchases of supplies.
Headwinds and fog delayed the departure of the expedition from Newburyport until September 19. In twelve hours, they reached the mouth of the Kennebec River. They spent the next two days negotiating the island channels near its mouth and sailing up the river.Martin (1997), p. 119 Arriving in Gardinerston on the 22nd, they spent the next few days at Reuben Colburn's house, organizing supplies and preparing the boats they would use for the rest of the expedition.Smith (1903), pp. 58–83 Arnold inspected Colburn's hastily constructed bateaux, finding them, in a portent of troubles to come, to be "very badly built", and "smaller than the directions given".Martin (1997), p. 120 Colburn and his crew spent the next three days building additional bateaux.
Arnold's troop movements did not escape British notice. General Thomas Gage in Boston was aware that Arnold's troops were "gone to Canada and by way of Newburyport", but he believed the target to be Nova Scotia, which was at the time virtually undefended.Randall (1990), p. 159 Francis Legge, the governor of Nova Scotia declared martial law, and on October 17 sent a message to England laden with rumors about American actions that turned out to be false. Admiral Samuel Graves eventually received intelligence about Arnold's activities, reporting on October 18 that the American troops "went up the Kennebec River, and 'tis generally believed are for Quebec".Randall (1990), p. 160
Scouting As the troop transports arrived, Arnold dispatched some of the men in the already-constructed bateaux up the Kennebec River to Fort Western, and the others by foot on a track leading to Fort Halifax, up the Kennebec. While waiting for the bateaux to be completed, Arnold received word from scouts Colburn had sent out to reconnoiter the proposed route. Their reports included rumors of a large Mohawk force near the southernmost French settlements on the Chaudière River. The source of these rumors was Natanis, a Norridgewock Indian believed to be spying for Quebec's governor, General Guy Carleton; Arnold discounted the reports.
Arnold and most of the force had reached Fort Western by September 23.Smith (1903), p. 83 The next day, Arnold sent two small parties up the Kennebec. One, under Pennsylvania Lieutenant Archibald Steele, was ordered to scout as far as Lake Mégantic to gather intelligence. The second, under Lieutenant Church, was to survey the route as far as the Dead River, at a place known to the local Indians as the Great Carrying Place, so that Arnold might better estimate how far the column would need to travel each day.
