"In 1866, six all-black cavalry and infantry regiments were created after Congress passed the Army Organization Act. Their main tasks were to help control the Native Americans of the Plains, capture cattle rustlers and thieves and protect settlers, stagecoaches, wagon trains and railroad crews along the Western front"
Now cattle ranchers didnt have to do long cattle drives. They could slaughter the cows on site then just send the meat, still fresh, via the refrigerated rail cars.
