If you didn't find the information you're looking for on this site; why not ask me? If I can't help you, I may be able to suggest where to look to get the answer.
Anyway, here's some of the information people have been looking for -
* The only ostensibly Scottish Catholic regiment I can think of would be the Glengarry Fencibles (1795-1802) which was raised from the mainly Catholic Macdonnells of western Inverness-shire and their neighbours for home defence duties. Many of its members went to Canada en masse after the regiment was disbanded and established Glengarry County in what is now Ontario.
* The grouping of buttons in threes on a scarlet tunic suggest it belonged to a soldier from the Scots Guards.
* The 1st Seaforth Highlanders and the 2nd Black Watch both suffered so many casualties in Mesopotamia that they formed a composite unit known as the Highland Battalion between February and July 1916.
* No, no "Seaforth Argylls". But when the depleted 2nd battalion of the Argyll and Sutherland Highlanders in Malaya was reinforced by Royal Marines in 1941 the unit was known as the "Plymouth Argylls".
* A black hackle worn on a Tam o'Shanter once signified the wearer belonged to the Cameronians. However, No. 11 (Scottish) Commando during the early years of the Second World War also wore black hackles. The Royal Scots Borderers, 1st Battalion Royal Regiment of Scotland, now wear the black hackle on their Tam o'Shanters.
* The Atholl Highlanders claim to be Europe's only legal private army. It is made up of friends and retainers of the Duke of Atholl.

"Cowan's retelling of the Scottish experience in Canada does an excellent job of giving an overview of the complex and compelling history of the country. Anyone who still clings to the old notion that Canada's history is boring (particularly in comparison to the Revolutionary beginnings and Wild West mythology of our southern neighbour) would have their eyes opened by reading Cowan's book." - Suite 101.
“entertaining and playful” - Celtic Connection magazine.
“Paul Cowan provides wonderful accounts of the explorers, settlers, rogues, politicians and charlatans who were Canada’s Scots.” - The Daily Gleaner.
“well written and informative” - Andrew Hinson, University of Guelph.
“This journalistic venture into Canadian history is a great success. Well written and humorous, it introduces the reader to well known and lesser known figures who, indeed, were the makers of Canada. Sir John A MacDonald, Colonel James F Macleod, Alexander MacKenzie and many more are well depicted in this fine book” - Alberta History
Who out there knows which war the 78th Fraser Highlanders fought in? Or where Keith’s Highlanders fought their battles? Whatever happened to the 70th Glasgow Lowland Regiment?
I’m guessing that some of you do – but my point is that history is not only written by the winners, it’s written by the survivors. The exploits of the Black Watch, Royal Scots, the Argyll and Sutherland Highlanders and the Cameronians are all reasonably well known. But what about the regiments that were raised and disbanded in the space of a couple of years? Or the Scottish regiments which morphed into Irish or English regiments? Some of these Scottish regiments had fighting records which equalled the Black Watch or the Camerons, but they have been consigned to the dustbin of history.
The British Government has always tried to keep the Army as small as possible – often in reality too small to do all the jobs required of it. The “can-do” attitude and making do with inferior equipment that has characterised the British Army has often meant men, and these days women, have died unnecessarily – a look at Iraq and Afghanistan shows nothing has changed.
That desire to keep the Army small – also a legacy of a fear of military coup which dates back to the days of Cromwell – meant that many regiments were formed in wartime and quickly disbanded when peace was restored. The British Army is usually regarded as being established in the reign of Charles II. One of the first Scottish regiments to be raised, Lockhart's, only existed from 1672 until 1674. Charles wanted it to fight against the Dutch and to be trained as marine battalion. The number of Gaelic-speaking Highlanders in its ranks made it difficult for the regiment to work with English speaking sailors. Most of the regiment was captured by the Dutch and while many of officers were taken to the Netherlands as prisoners, most of the rank-and-file were dumped back on the south coast of England. The regiment was re-raised but disbanded about three months later when war against the Dutch ended in February 1674.
King William III had 15 Scottish regiments fighting for him in Europe between 1694 and 1697. Earlier, in 1692, no fewer than 11 of the 25 British regiments King William sent to Europe were Scots.
War is hell and the winning side is often the one which makes the fewest mistakes. The Scots are justly proud of their fighting men and women but mistakes have been made. Best-selling author Paul Cowan turns his attention to the disasters which have befallen Scotland’s soldiers over the centuries. His sharp eye for anecdotal detail, ranging from the gory to the humorous, help make this engaging account of military fiascos, catastrophes and blunders involving Scotland’s proud fighting men come alive for the general reader. Why should soldiers' stories only be told when they're on the winning side?
From some reviews of Scottish Military Disasters
"Author and war journalist Paul Cowan gives a pithy thumbnail sketch of each battle or incident (the longest episode is nine pages), and sets each event in the context of its time and also lists, where appropriate, its military or historical consequences. All in all, it is a cracking good read."
--Brian Townsend, The Courier
"[T]his pacy, lucidly written history is extremely readable and highly informative"
—Martin Tierney, The Herald
"A fascinating and highly recommended read."
—Ian Smith, Scots Magazine
