From Hessians: Mercenaries, Rebels, and the War for British North America, by Brady J. Crytzer (Westholme, 2015), Kindle Loc. 1331-39, 1366-86:
The [Hessian] captain’s fascination with partisan warfare make his recollections especially insightful; nearby villages, most notably the former rebel post at Peekskill, were now all but abandoned. Surrounding him in the days that followed their victories were a motley collection of soldiers, none of whom could be identified as Englishmen. Along with his Jägers from Hesse-Cassel, Ewald noted that much of the fighting was accomplished by fellow Germans from Anspach as well as a multitude of Irish volunteers. Ewald would have been considered a hardened veteran of wilderness combat and his Jägers in their forest green had been on the continent almost continuously with him since 1776. In contrast, the Anspachers, who spoke his mother tongue in their royal blue jackets and tall black fur caps, had only been in America for days. Those representing the Emerald Isle were assembled from within existing provincial units by the Irish Lord Francis Rawdon-Hastings during the occupation of Philadelphia in 1777. These Irish volunteers had performed so well that they were named the 2nd American Regiment. Although the American Patriot politicians desired a clear enemy to vilify, King George’s imperial forces were actually something of a patchwork army.
It was soon revealed that this mysterious Loyalist ranger was in the service of Lieutenant Colonel John Butler, and he had seen more than his fair share of action. Butler, a native of New York’s war-torn Mohawk River valley, was for many the face of the Loyalist movement in the colonies. He led dozens of his “rangers” across the frontier, raiding Patriot homesteads and villages with extreme prejudice. Fighting with Butler in the service of the Crown were the warriors of the Seneca, Cayuga, Onondaga, and Mohawk nations, collectively known as the Iroquois Confederacy. The Iroquois had been longtime allies of the British Empire before the conflict, and following the defection of the Oneida and Tuscarora to the Patriot side they were almost fully aligned with the king. The unified forces of Butler’s rangers and the Iroquois warriors saw some of the most brutal fighting of the entire war, and were considered a vital part of Britain’s overall strategy for success in the colonies.
Ewald was familiar with the exploits of men like Butler and Joseph Brant, sachem of the Mohawk, and his guest claimed to have served alongside both. Ewald proceeded to inquire into his experiences, and as a testament to his deep interest made a nearly exact transcription of their conversation in the glow of the campfire that evening. He began by asking about Butler’s overall strength; the man replied that he had fifty Loyalist Americans and upwards of five hundred Indian warriors on hand.
The tactician Ewald could not help but inquire as to how they supported such a large force of men in such difficult wilderness conditions. The ranger explained that in the beginning they lived entirely on the wild game hunted by the Indian warriors. As soon as they reached the borders of Pennsylvania and Maryland, though, they found provisions in abundance. It was clear to Ewald at that point that this man must have had a range of hundreds of miles during his guerilla campaign. But what of the ferocity of the Indians? The Jäger captain was a man of modern European military training, and the tales of the Indian fighting style was as ferocious as they were legendary.
The stranger explained that they rarely took prisoners, and every man, woman, or child was either cut down or carried off. He continued by claiming that the dwellings were plundered, devastated, and burned. He concluded his conversation by recalling that he and his Indian allies killed two entire regiments along the Susquehanna River with no thoughts of taking a single prisoner. To Ewald this was a great affront. The European tradition of war grew out of medieval chivalric values under which men who surrender were allowed the dignity to live to fight another day. The Indian tradition of war, however, was largely in place centuries earlier. It seemed that 1492 and its aftermath could do little to redirect it.
