So Braddock's Expedition is a bit confusing because American historians all talk about his two regiments, and military historians of the Nineteenth Century know that's about ten thousand men, which is a huge force by the standards of Eighteenth Century colonial warfare, and meanwhile military historians of the Eighteenth Century are, like, "what's a regiment?" It's not inaccurate, in that regiments did exist in the Eighteenth Century as political, financial and administrative elements, and the particular two battalions of the Irish Establishment that came out with Braddock belonged to single battalion regiments. American military historians are probably informed by reading about the Civil War, where, as was often the case in that era, it was found necessary to insert an additional tier in the command structure of the Age of Reason. That is, in 1755 there were so many companies per battalion, so many battalions per brigade, so many brigades per [insert tedious historiographical discussion here] division. In 1860, armies with lots of conscripts found that this wasn't enough supervision and turned the regiment into an organisational level between battalion and brigade. Conscripts, and their ROTC officers, just need more attention from more headquarters because they can't be trusted to know what they're doing on their own.
The aftermath of Braddock's Defeat is also confusing, because, we are told, a wave of Indian attacks caused settlers to abandon frontier settlements and flee eastward, with a strong subtext of a racial war against the Westward Drive, Frontier Spirit, and Manifest Destiny. And we are not told wrong, except that, with the exception of three extraordinary attacks, the trouble took place in what was then Pennsylvania's Northumberland County, now Monroe and Pike counties, or, in Eighteenth Century usage, the "Minisink Valley," which is not a valley at all, but the region north of the Delaware Water Gap cupped by the Poconos Mountains that was shared between Pennsylvania, New York, and West Jersey, as it still was. The attacks were absolutely Indian attacks, made specifically by the followers of Teedyuscung, probably a grandson of Tamanend and, if my tinfoil hat isn't fitting too tight, William Penn, with an internally Pennsylvanian objective, which was why the raiders spared New York and New Jersey, and why the raids were probably actually a pogrom, which is why almost all the attacks killed the patriarchs of the settlements raided, and probably why there's a slightly panicked subtext to Ben Franklin's reports about the refugees gathering in New Jersey. Because if they weren't leading members of these families, they were probably mostly enslaved. This was a Pennsylvanian civil war. The racial component isn't "Scotch-Irish" versus Indians, but rather a peasant's revolt.
No wonder, then, that the Pennsylvanian Assembly settled quickly in the 1758 Treaty of Easton. But before that could happen, and just to drag this preamble around to relevance, Henri Bouquet, the Swiss Protestant (that is, Francophone) favourite of the Duke of Cumberland, had arrived in Philadelphia and there formed, not to get all genealogical, one of the ancestral units of the King's Royal Rifle Corps, most easily searched, I suspect, as the 60th (American) Rifles. Per the source most recently consulted --probably Wikipedia, but I forget-- this was formed from immigrant German workingmen. Wikipedia does not note that in 1756 the Germans who were immigrating to Philadelphia were mostly coming from German Flats, far up the Mohawk, where a German-speaking community had been growing by ethnogenesis from 1719. With regards to the demographic raw material, this can only have been the free Blacks who could not exist as such in the Eighteenth Century American cosmic order. This probably explains why Bouquet didn't need to subject his riflemen to some specialised training regime to turn them into another of the mid-Eighteenth Century's many ethnically-recruited special forces.Which is usually a bit of an anachronism in that the European units that trace their tradition to the Eighteenth Century special forces have all been long since de-specialed, pipe bands apart.
The American ranger tradition is an exception, and one that, I suggest, is rooted in race, not the primeval (hah!) forest of the American frontier.
