Here is one they did not teach us in school,as go against the Queen's narrative it does...

[....The Bluecoats, many of them veterans of the Civil War, had survived the most brutal deprivations—the “Hornet’s Nest” at Shiloh, Stonewall Jackson’s “River of Death” on the banks of the Chickahominy, the bloody Sunken Road at Antietam. They had held firm to cover the retreat at Bull Run and stood with Kit Carson at Valverde Ford. But the onset of the winter of 1866 was introducing them to a new kind of hardship as they broke trail through the rugged Powder River Country, the only sounds the creak of their frozen tack and the moan of the north wind as it tore through the stunted branches of scrub oak that choked the river corridors.

It was November 2, and it had taken the sixty-three officers and enlisted men of Company C of the 2nd U.S. Cavalry more than a month to traverse the nearly 700 miles from the flatlands of eastern Nebraska to the head of the Bozeman Trail in south central Wyoming. They had traced the great bend of the North Platte across gale scoured plains, climbed onto mile-high prairie whose altitude made their lungs wheeze and their heads ache, and forded more than two dozen ice-crusted rivers and streams.

Now, veering west from the South Powder, they disappeared into the rolling buttes that buckled and folded to the northern horizon. The riders were still a day’s journey from their destination, the isolated Fort Phil Kearny, a seventeen-acre redoubt on the fork of Little Piney Creek and Big Piney Creek just shy of the Montana border. With their black woolen sack coats cinched tight and their greasy kepis and Hardees pulled low against their foreheads, from a twilit distance the party could well have been mistaken for a column of wizened buffalo picking its way through the rugged Dakota Territory. 1

Along the trail they had passed a great many grave sites holding the remains of white men and women murdered by Indians.

The soldiers, reinforcements from the East, were unaccustomed to the ferocity of the poudrerie whiteouts that funneled down from the Canadian Plains. Though the biting northers had left the tops of the surrounding foothills and tabletops bald and brown, Company C’s horses and wagon mules pushed through creek bottoms and coulees piled high with snowdrifts that sometimes reached their withers. That night they bivouacked in a narrow gulch, where a spinney of bare serviceberry trees formed a windbreak. Above them loomed the east face of the Bighorn Mountains, a 12,000-foot fortress of granite that few whites had ever seen.....]
