 After the war, Black Beaver and his friend Jesse Chisholm returned and developed part of the Native American path used by the Union Army into what became known as the Chisholm Trail.They collected and herded thousands of stray Texas longhorn cattle by the Trail to railheads in Kansas, from where the cattle were shipped East, where beef sold for ten times the price in the West.The Chisholm Trail was used by other cowboys to drive millions of cattle to Kansas for shipment to the East.
