Woof! Woof! Remember these old western television stories of the 1950's? Stories of the Century - The Doolin Gang 1 of 3? It is an anthology of the Old West's greatest outlaws. How accurate they are is yet to be determined, though.
If you do a Wikipedia search for the "Doolin Gang," you might find that the Doolin-Dalton gang was also known as the "Wild Bunch." Their outlaw headquarters was based in Indian Territory, and they terrorized Kansas, Missouri, Arkansas and Oklahoma Territory during the 1890s, robbing banks and stores, holding up trains, and killing lawmen.
They were also known as "The Oklahoma Long Riders" because of the long dusters that they wore. Of all the outlaw gangs of the American Old West, none met a more violent end than the "Wild Bunch," with only two of its eleven members surviving into the 20th century, and all eleven met violent deaths in gun battles with lawmen.
The gang consisted at various times of William "Tulsa Jack" Blake, Dan "Dynamite Dick" Clifton, Roy Daugherty (a.k.a. "Arkansas Tom Jones"), William Marion "Bill" Dalton, Bill Doolin, George "Bittercreek" Newcomb (aka "Slaughter Kid"), Charley Pierce, William F. "Little Bill" Raidler, George "Red Buck" Waightman, Richard "Little Dick" West, and Oliver "Ol" Yantis. Additionally, two teenaged girls followed the gang, known as "Little Britches" and "Cattle Annie," and informed the men about the location of law enforcement officers whenever they were in pursuit of the criminals.
