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.

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 attention to 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.

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. Arriving in Gardinerston on the 22nd, they spent the next few days there, organizing supplies and preparing the boats they would use for the rest of the expedition. 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". Colburn and his crew spent the next three days building additional bateaux.

; Arnold discounted the reports.

 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.

Early troubles

The full expedition set out from Fort Western on September 25. Morgan's riflemen led the way, blazing trails when necessary. Colburn and a crew of boatwrights came in the rear, to repair bateaux as needed. Morgan's group traveled relatively lightly, as they would be working to make the trail, while the last group, commanded by Lieutenant Colonel Enos, carried the bulk of the supplies. The expedition arrived at its first target, Fort Halifax, a decaying relic of the French and Indian War

The French and Indian War is the common American name for the war between Great Britain and France in North America from 1754 to 1763. In 1756, the war erupted into the world-wide conflict known as the Seven Years' War and thus came to be regarded as the North American theater of that war...

 so that he might move more rapidly among the troops along the travel route.

Arnold reached Norridgewock Falls, location of the last settlements on the Kennebec, on October 2. Even at this early date, problems were apparent. The bateaux were leaking, resulting in spoiled food and a continual need for repairs. The men were constantly wet, due not only to the leakage but also the frequent need to pull the heavy boats upstream. As temperatures began to drop below freezing, colds

 set in, reducing the effectiveness of the force.

The portage around Norridgewock Falls, a distance of about one mile (1.6 km), was accomplished with the assistance of oxen provided by the local settlers, but it took almost a week to complete; Arnold did not depart from there until October 9. Colburn's crew devoted some of this time to making repairs on the bateaux. Most of the expedition reached the Great Carrying Place on October 11, and Arnold arrived the next day. This stretch of the trek was complicated by heavy rains, rendering the portages difficult due to extremely muddy conditions.

The Great Carrying Place

The Great Carrying Place was a portage of roughly 12 miles (19 km), bypassing an unnavigable section of the Dead River, the tributary of the Kennebec that the expedition was to follow. The portage included a rise in elevation of about 1,000 feet (305 m) to the high points of the carry, with three ponds along the way. Lieutenant Church, the leader of the survey team, described the route as a "bad road but capable of being made good", an assessment that turned out to be somewhat optimistic.

The vanguard of the main body, led by Daniel Morgan, met Lieutenant Steele's advance scouting party en route to the first pond. This party had successfully scouted the route to the height of land above the Dead River, but the men were near starvation. Their supplies had been depleted, and they were largely subsisting on a protein-rich diet of fish, moose, and duck. Most of the men continued to supplement their meager supplies with the local wildlife as the expedition continued.

Church, in his description of the route, had failed to account for the heavy rains and the generally boggy conditions between the first and second ponds. Rain and snow slowed the long portage, and the expedition had its first casualty when a falling tree killed one of the party. Some of the men who drank the brackish waters along the way became violently ill, forcing Arnold to order construction of a shelter at the second pond as cover for the sick, and to send some men back to Fort Halifax for supplies that had been cached there.

The first two battalions finally reached the Dead River on October 13, and Arnold arrived three days later. At this point, Arnold wrote a number of letters informing Washington and Montgomery of his progress. Several letters intended for Montgomery were intercepted and turned over to Quebec's Lieutenant Governor Hector Theophilus de Cramahé

, giving Quebec its first notice that the expedition was on its way. Arnold also dispatched the survey team again, this time to mark the trail all the way to Lake Mégantic.

Ascending the Dead River

Progress up the Dead River was extremely slow. Contrary to its name, which supposedly described the speed of its currents, the river was flowing rapidly enough that the men had trouble rowing and poling against the current. The leaky boats spoiled more of the food, forcing Arnold to put everyone on half rations. Then, on October 19, the skies opened, and the river began to rise in the pouring rain. Early on October 22, the men awoke to discover that the river had risen to the level of their camp, and they had to scramble to even higher ground for safety. When the sun rose they were surrounded by water.

After spending most of that day drying out, the expedition set off on October 23. Precious time was lost when some of the men mistakenly left the Dead River and ascended one of its branches, having been fooled by the high water. Soon after, seven bateaux overturned, spoiling the remaining food stores. This accident compelled Arnold to consider turning back. He called together his nearby officers for a council of war

. Arnold explained that although the situation was grim, he thought that the expedition should continue. The officers agreed, and decided to pick an advance party that would proceed as rapidly as possible to French settlements on the Chaudière, and work to bring supplies back. The sick and infirm were to retreat to American settlements in Maine.

Further back on the route, Lieutenant Colonel Greene and his men were starving. They had little flour, and were consuming candle wax and shoe leather to supplement their minimal rations. On October 24, Greene attempted to catch up with Arnold, but was unable to do so because Arnold had moved too far ahead. When he returned to camp, Lieutenant Colonel Enos had arrived, and they held their own council. Enos's captains were united in wanting to turn back despite Arnold's most recent orders, which were to press ahead. In the council, Enos cast a tie-breaking vote in favor of continuing, but in a meeting with his captains after the council, announced that because they were insistent on returning, he was acceding to their decision, and would return. After giving Greene's men some of his supplies, Enos and 450 men turned back.


Lake Mégantic

The impact of the inaccurate maps was felt when the expedition reached the height of land. Portions of the advance party became lost in swampy bogs (the area surrounding Spider Lake on the topographic map shown above) that were not on those maps, resulting in delays reaching Lake Mégantic. Although this part of the party crossed the height of land on October 25, it was not until two days later that they reached the lake. On October 28, the advance party descended the upper Chaudière, destroying three of their bateaux when they turned over and crashed into rocks above some falls on the river.

, the southernmost French settlement on the Chaudière.

Arnold, when he reached Lake Mégantic, sent a man back to the two remaining battalions with instructions on how to navigate the swampy lands above the lake. However, the way Arnold described the route included information from the incorrect maps that he had not seen on the route. As a result, some elements of the expedition spent two days lost in swamps before the majority finally reached the falls on the upper Chaudière on October 31. Along the way, Captain Henry Dearborn

Arrival at Quebec

Arnold first made contact with the local population on October 30. Sympathetic to his plight, they supplied provisions and cared for the sick; some were well paid for their aid, while others refused payment. Arnold distributed copies of a letter written by Washington asking the habitants to assist the expedition, and Arnold added promises to respect the persons, property, and religion of the locals.

, notified Arnold that Lieutenant Governor Cramahé had ordered the destruction of all boats on the southern banks of the Saint Lawrence after receiving the intercepted communications.

On November 9 the expedition finally reached the Saint Lawrence at Pointe-Levi, across the river from Quebec. Arnold had about 600 of his original 1,100 men, and the journey had turned out to be 350 miles (560 km), not the 180 that Arnold and Washington had thought it would be. From John Halstead, a New Jersey-born businessman who operated a mill near Pointe-Levi, Arnold learned of the arrest of his courier and the interception of some of his letters. Halstead's mill became the organizing point for the crossing of the Saint Lawrence. Some of Arnold's men purchased canoes from the habitants and the local Saint Francis Indians, and then transported them from the Chaudière to the mill site. The forces crossed the Saint Lawrence on the night of November 13–14 after three days of bad weather, likely crossing the mile-wide river between the positions of HMS Hunter and HMS Lizard

 on December 31. The battle was a devastating loss for the Americans; Montgomery was killed, Arnold was wounded, and Daniel Morgan was captured along with more than 350 men. Arnold did not learn until after the battle that he had been promoted to brigadier general for his role in leading the expedition.

The invasion ended with a retreat back to Fort Ticonderoga

, Montgomery's starting point, during the spring and summer of 1776. Arnold, who commanded the army's rear guard in the later stages of the retreat, was able to delay the British advance sufficiently to prevent them from attempting to reach the Hudson River in 1776.

Lieutenant Colonel Roger Enos and his detachment arrived back in Cambridge late in November. Enos was promptly court-martialed, charged with "quitting his commanding officer without leave". He was acquitted, but was not treated well in camp. He resigned his commission shortly thereafter, and saw no more Continental service in the war. Reuben Colburn was never paid for his work, despite promises made by Arnold and Washington; the expedition ruined him financially.
