June 27, 1874, Adobe Walls, Tex.
The outpost was laid siege by Indians(native Americans) Several buffalo hunters are killed. BTW Bat Masterson was there.
At the behest of one of the hunters, Billy Dixon, already renowned as a crack shot, took aim with a 'Big Fifty' Sharps (it was either a .50-70 or -90, probably the latter) he'd borrowed from Hanrahan, and cleanly dropped a warrior from atop his horse. This apparently so discouraged the Indians they decamped and gave up the fight. Two weeks later a team of US Army surveyors, under the command of Nelson A. Miles, measured the distance of the shot: 1,538 yards, or nine-tenths of a mile. For the rest of his life, Billy Dixon never claimed the shot was anything other than a lucky one; his memoirs do not devote even a full paragraph to 'the shot'.
I've got the site in my GPS and one day drive out there. Over a thousand miles though.
