The Marshal's Band was a POSSE of five members, led by the U.S. Marshal, that was formed in the late 19th century to help enforce law and order in the American West. The POSSE was made up of experienced lawmen and cowboys who were tasked with apprehending criminals and bringing them to justice. The POSSE was also responsible for protecting settlers and their property from outlaws and Native Americans. The Marshal's Band was an important part of the Wild West and helped to bring law and order to the region.
