Corrected entry: When Tunstall is shot they make it look like it happened on New Years Day but it actually happened on Feb. 18.
Corrected entry: At the end of the movie Charlie Bowdre is shown in a gun battle with a Murphy man and they end up killing each other. Historically, Charles Bowdre was killed by Pat Garret in 1880, 2 years after the McSween battle.
Corrected entry: At the end of the battle at McSweens home Billy the Kid is shown returning to town to shoot L.G. Murphy between the eyes. This is a complete fabrication. L.G Murphy died of cancer on the 20th of October 1878 almost 3 months to the day after the battle at the McSween home.
Corrected entry: In the part of the movie where the boys open fire with all their guns in the close-up of all the pistols going off, there is clearly a double action revolver being fired. Up until the early 1900's Colt only offered a single action revolver where the hammer had to be drawn back each time you pulled the trigger.
