Whitey did not get away with everything as is being claimed,a high price was paid for the west,we take for granted....

Captain William Judd Fetterman crested Pilot Knob at the head of Lieutenant Horatio Bingham’s company of the 2nd Cavalry on the morning of November 3, 1866. It was two days after the attack on the last civilian wagon train bound for Montana and, in Margaret Carrington’s words, his return to his old battalion had been “looked for with glad anticipation.” The snowbound ravines and coulees the party had just traversed were nearly impassable, and Fetterman may have been puzzled as to why the outpost spread before him at the foot of the Bighorns was merely dusted with snow, and why even less was accumulated on the surrounding hilltops and ridge lines. Actually, just four miles to the west of Fort Phil Kearny four feet of powder covered the lower slopes of the mountains. Despite his unfamiliarity with the frontier, however, he surely admired what he saw. Inside the stout pine walls dozens of buildings had been completed or were nearing completion, and from the top of Pilot Knob the post gave the impression of a good redoubt from which to conduct his hunt for Red Cloud.

and he finds him all right
