The regiment known as Montgomery's Highlanders (77th) took its name from its commander, Archibald Montgomery, son of the earl of Eglinton. Being very popular among the Highlanders, Montgomery very soon raised the requisite body of men, who were formed into thirteen companies of one hundred and five rank and file each; making in all fourteen hundred and sixty effective men, including sixty-five sergeants and thirty pipers and drummers. The Colonel's commission was dated January 4, 1757, and those of the other officers one day later than his senior in rank. They are thus recorded:

Lieut.-Colonel commanding, Archibald Montgomery; majors, James Grant of Ballindalloch and Alexander Campbell; captains, John Sinclair, Hugh Mackenzie, John Gordon, Alexander Mackenzie, William Macdonald, George Munro, Robert Mackenzie, Allan Maclean, James Robertson, Allan Cameron; captain-lieut., Alexander Mackintosh; lieutenants, Charles Farquharson, Nichol Sutherland, Donald Macdonald, William Mackenzie, Robert Mackenzie, Henry Munro, Archibald Robertson, Duncan Bayne, James Duff, Colin Campbell, James Grant, Alexander Macdonald, Joseph Grant, Robert Grant, Cosmo Martin, John Macnab, Hugh Gordon, Alexander Macdonald, Donald Campbell, Hugh Montgomery, James Maclean, Alexander Campbell, John Campbell, James Macpherson, Archibald Macvicar; ensigns: Alexander Grant, William Haggart, Lewis Houston, Ronald Mackinnon, George Munro, Alexander Mackenzie, John Maclachlane, William Maclean, James Grant, John Macdonald, Archibald Crawford, James Bain, Allan Stewart; chaplain: Henry Munro; adjutant: Donald Stewart; quarter-master: Alexander Montgomery; surgeon: Allan Stewart.

The regiment embarked at Greenock for Halifax immediately on its organization.

Fraser's Highlanders, or the 78th Regiment was organized by Simon Fraser, son of the notorious lord Lovat who was executed by the English government for the part he acted in the Rising of the Forty-five. Although his estates had been seized by the Crown, and not possessing a foot of land, so great was the influence of clanship, that in a few weeks he raised eight hundred men, to whom were added upwards of six hundred more by the gentlemen of the country and those who had obtained commissions. In point of the number of companies and men, the battalion was precisely the same as Montgomery's Highlanders. The list of officers, whose commissions are dated January 5, 1757, is as follows:

Lieut.-col. commandant: Simon Fraser; majors: James Clephane and John Campbell of Dunoon; captains: John Macpherson, brother of Cluny, John Campbell of Ballimore; Simon Fraser of Inverallochy, Donald Macdonald, brother of Clanranald, John Macdonell of Lochgarry, Alexander Cameron of Dungallon, Thomas Ross of Culrossie, Thomas Fraser of Strui, Alexander Fraser of Culduthel, Sir Henry Seton of Abercorn and Culbeg, James Fraser of Belladrum; capt.-Lieut.: Simon Fraser; lieutenants: Alexander Macleod, Hugh Cameron, Ronald Macdonell, son of Keppoch, Charles Macdonell, from Glengarry, Roderick Macneil of Barra, William Macdonell, Archibald Campbell, son of Glenlyon, John Fraser of Balnain, Hector Macdonald, brother of Boisdale, Allan Stewart, son of Innernaheil, John Fraser, Alexander Macdonald, son of Boisdale, Alexander Fraser, Alexander Campbell of Aross, John Douglas, John Nairn, Arthur Rose, Alexander Fraser, John Macdonell of Leeks, Cosmo Gordon, David Baillie, Charles Stewart, Ewen Cameron, Allan Cameron, John Cuthbert, Simon Fraser, Archibald Macallister, James Murray, Alexander Fraser, Donald Cameron, son of Fassifern; ensigns: John Chisolm, Simon Fraser, Malcolm Fraser, Hugh Fraser, Robert Menzies, John Fraser of Errogie, James Mackenzie, Donald Macneil, Henry Munro, Alexander Gregorson, Ardtornish, James Henderson, John Campbell; chaplain: Robert Macpherson; adjutant: Hugh Fraser; quarter-master: John Fraser; surgeon: John Maclean.

"The uniform of the regiment was the full Highland dress with musket and broadsword, to which many of the soldiers added the dirk at their own expense, and a purse of badger's or otter's skin. The bonnet was raised or cocked on one side, with a slight bend inclining down to the right ear, over which were suspended two or more black feathers. Eagle's or hawk's feathers were usually worn by the gentlemen, in the Highlands, while the bonnets of the common people were ornamented with a bunch of the distinguishing mark of the clan or district. The ostrich feathers in the bonnets of the soldiers were a modern addition of that period."[136]

The regiment was quickly marched to Greenock, where it embarked, in company with Montgomery's Highlanders, and landed at Halifax in June 1757, where it remained till it formed a junction with the expedition against Louisbourg. The regiment was quartered between Canada and Nova Scotia till the conclusion of the war. On all occasions they sustained a uniform character for unshaken firmness, incorruptible probity and a strict regard to their duties. The men were always anxious to conceal their misdemeanors from the Caipal Mohr, as they called the chaplain, from his large size.

When The Black Watch landed in New York they attracted much notice, particularly on the part of the Indians, who, on the march of the regiment to Albany, flocked from all quarters to see strangers, whom, from the somewhat similarity of dress, they believed to be of the same extraction with themselves, and therefore considered them to be brothers.

During the whole of 1756 the regiment remained inactive in Albany. The winter and spring of 1757 they were drilled and disciplined for bush-fighting and sharpshooting, a species of warfare then necessary and for which they were well fitted, being in general good marksmen, and expert in the management of their arms.
