1861, Wild Bill Hickok’s first gunfight.

Wild Bill Hickok begins to establish his reputation as a gunfighter after he shoots three men during a shootout in Nebraska.

Born in Homer (later called Troy Grove), Illinois, James Butler Hickok moved to Kansas in 1855 at the age of 18. There he filed a homestead claim, took odd jobs, and began calling himself by his father’s name, Bill. A skilled marksman, Hickok honed his abilities as a gunslinger. Though Hickok was not looking for trouble, he liked to be ready to defend himself, and his ability with a pistol soon proved useful.

By the summer of 1861, Hickok was working as a stock tender at a stage depot in Nebraska called Rock Creek Station. Across the creek lived David McCanles, a mean-spirited man who disliked Hickok for some reason. McCanles enjoyed insulting the young stockman, calling him Duck Bill and claiming he was a hermaphrodite. Hickok took his revenge by secretly romancing McCanles’ mistress, Sarah Shull.

On this day in 1861, the tension between Hickok and McCanles came to a head. McCanles may have learned about the affair between Shull and Hickok, though his motivations are not clear. He arrived at the station with two other men and his 12-year-old-son and exchanged angry words with the station manager. Then McCanles spotted Hickok standing behind a curtain partition. He threatened to drag “Duck Bill” outside and give him a thrashing. Demonstrating remarkable coolness for a 24-year-old who had never been involved in a gunfight, Hickok replied, “There will be one less son-of-a-bitch when you try that.”

McCanles ignored the warning. When he approached the curtain, Hickok shot him in the chest. McCanles staggered out of the building and died in the arms of his son. Hearing the shots, the two other gunmen ran in. Hickok shot one of them twice and winged the other. The other workers at the station finished them off.

The story of Hickok’s first gunfight spread quickly, establishing his reputation as a skilled gunman. In 1867, Harper’s New Monthly Magazine published a highly exaggerated account of the shoot-out which claimed Hickok had single-handedly killed nine men. The article quoted Hickok as saying, “I was wild and I struck savage blows.” Thus began the legendary career of “Wild Bill.”

For the next 15 years, Hickok would further embellish his reputation with genuine acts of daring, though the popular accounts continued to exceed the reality. He died in 1876 at the age of 39, shot in the back of the head by a young would-be gunfighter looking for fame.

1876 Battle of the Little Bighorn.

On June 25, 1876, Native American forces led by Crazy Horse and Sitting Bull defeat the U.S. Army troops of Lt. Col. George Armstrong Custer in the Battle of the Little Bighorn near southern Montana’s Little Bighorn River.

Crazy Horse and Sitting Bull, Lakota Sioux leaders, strongly resisted the mid-19th-century efforts of the U.S. government to confine their people to reservations. In 1875, after gold was discovered in South Dakota’s Black Hills, the U.S. Army ignored previous treaty agreements and invaded the region. This betrayal led many Sioux and Cheyenne tribesmen to leave their reservations and join Sitting Bull and Crazy Horse in Montana. By the late spring of 1876, more than 10,000 Native Americans had gathered in a camp along the Little Bighorn River–which they called the Greasy Grass—in defiance of a U.S. War Department order to return to their reservations or risk being attacked.

In mid-June, three columns of U.S. soldiers lined up against the camp and prepared to march. A force of 1,200 Native Americans turned back the first column on June 17. Five days later, General Alfred Terry ordered Custer’s 7th Cavalry to scout ahead for enemy troops. On the morning of June 25, Custer drew near the camp and decided to press on ahead rather than wait for reinforcements.

At mid-day, Custer’s 600 men entered the Little Bighorn Valley. Among the Native Americans, word quickly spread of the impending attack. The older Sitting Bull rallied the warriors and saw to the safety of the women and children, while Crazy Horse set off with a large force to meet the attackers head on. Despite Custer’s desperate attempts to regroup his men, they were quickly overwhelmed. Custer and some 200 men in his battalion were attacked by as many as 3,000 Native Americans; within an hour, Custer and every last one of his soldiers was dead.

The Battle of the Little Bighorn—also called Custer’s Last Stand—marked the most decisive Native American victory and the worst U.S. Army defeat in the long Plains Indian War. The gruesome fate of Custer and his men outraged many white Americans and confirmed their image of the Native Americans as "wild." Meanwhile, the U.S. government increased its efforts to subdue the tribes. Within five years, almost all of the Lakota Sioux and Cheyenne would be confined to reservations.
