Some 75 million buffalo roamed the American plains in the early 19th century. As settlers moved in in the mid 1800's, the buffalo was one of the first animals to suffer at the hands of civilization.
The Texas herd alone, estimated at about 10 million head, were slaughtered to near extinction by a mere 2000 hunters in a matter of three or four years. By 1879 these great heards were reduced to a few straggling calves and yearlings. It was the end of an era, the last and greatest unrestricted hunt in history.
