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, two Royal Navy ships that were guarding the river against such a crossing. The city of Quebec was then defended by about 150 men of the Royal Highland Emigrants under Lieutenant Colonel Allen Maclean, supported by about 500 poorly organized local militia and 400 marines from the two warships. When Arnold and his troops finally reached the Plains of Abraham on November 14, Arnold sent a negotiator with a white flag to demand their surrender, to no avail. The Americans, with no cannons or other field artillery, and barely fit for action, faced a fortified city. After hearing rumors of a planned sortie from the city, Arnold decided on November 19 to withdraw to Pointe-aux-Trembles to wait for Montgomery, who had recently captured Montreal. Aftermath When Montgomery arrived at Pointe-aux-Trembles on December 3, the combined force returned to the city and began a siege, finally assaulting it 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. Enos and his detachment arrived back in Cambridge late in November. Enos was court-martialed, charged with "quitting his commanding officer without leave". He was acquitted, and returned to service as Lieutenant Colonel of the 16th Connecticut Regiment. John Sullivan, the court-martial President, made public a written statement in support of Enos' conduct, and other officers also issued a public circular to support Enos, including William Heath, John Stark, Joseph Reed, and James Reed. Enos subsequently moved to Vermont, where he served in the militia as Colonel, Brigadier General and Major General, including commanding troops on the Vermont side of Lake Champlain during the Saratoga campaign to deter John Burgoyne from foraying into Vermont.
