The men belonging to the first battalion were assembled at Quebec. On the approach of the American army by Lake Champlain, Colonel Maclean was ordered to St. Johns with a party of militia, but got only as far as St. Denis, where he was deserted by his men. When Quebec was threatened by the American army under Colonel Arnold, Colonel Maclean with his regiment consisting of three hundred and fifty men, was at Sorel, and being forced to decamp from that place, by great celerity of movement, evaded the army of Colonel Arnold and passed into Quebec with one hundred of his regiment. He arrived just in time, for the citizens were about to surrender the city to the Americans. On Colonel Maclean's arrival, November 13, 1775, the garrison consisted only of fifty men of the Fusiliers and seven hundred militia and seamen. There had also just landed one hundred recruits of Colonel Maclean's corps from Newfoundland, which had been raised by Malcolm Fraser and Captain Campbell. Also, at the same time, there arrived the frigate Lizard, with L20,000 cash, all of which put new spirits into the garrison. The arrival of the veteran Maclean greatly diminished the chances of Colonel Arnold. Colonel Maclean now bent his energies towards saving the town; strengthened every point; enthused the lukewarm, and by emulation kept up a good spirit among them all. When General Carleton, leaving his army behind him, arrived in Quebec he found that Colonel Maclean had not only withstood the assaults of the Americans but had brought order and system out of chaos. In the final assault on the last day of the year, when the brave General Montgomery fell, the Highlanders were in the midst of the fray. Many of the Americans were captured at this storming of Quebec. One of them narrates that "January 4th, on the next day, we were visited by Colonel Maclean, an old man, attended by other officers, for a peculiar purpose, that is, to ascertain who among us were born in Europe. We had many Irishmen and some Englishmen. The question was put to each; those who admitted a British birth, were told they must serve his majesty in Colonel Maclean's regiment, a new corps, called the emigrants. Our poor fellows, under the fearful penalty of being carried to Britain, there to be tried for treason, were compelled by necessity, and many of them did enlist."[153] Such men could hardly prove to be reliable, and it can be no astonishment to read what Major Henry Caldwell, one of the defenders of Quebec says of it: "Of the prisoners we took, about 100 of them were Europeans, chiefly from Ireland; the greatest part of them engaged voluntarily in Col. McLean's corps, but about a dozen of them deserting in the course of a month, the rest were again confined, and not released till the arrival of the Isis, when they were again taken into the corps."[154]
