A stagecoach robbery involves the theft of valuables from a stagecoach, which was a common mode of transportation in the 19th century. These robberies typically occurred in remote areas where bandits could ambush the coach and its passengers. The robbers often targeted stagecoaches carrying money, mail, or other valuable goods, taking advantage of the slow-moving vehicle. The most famous stagecoach robberies took place in the American West, where outlaws like Jesse James and Butch Cassidy became notorious for their daring heists. Law enforcement and private security companies eventually developed strategies to protect stagecoaches, leading to a decline in such robberies by the late 1800s.
