How did curly bill (william brocius) affect the westward expansion

William B. "Curly Bill" Brocius (or Brocious) was an outlaw leader of the Clanton Gang of Arizona

William Brocius (c. 1845 - March 24, 1882) had a number of conflicts with the lawmen of the Earp family, and he was named as one of the individuals who participated in Morgan Earp's assassination. Deputy U. S. Marshal Wyatt Earp and a group of deputies including his brother Warren Earp pursued those they believed responsible for Morgan's death. The Earp posse unexpectedly encountered Curly Bill and other Cowboys on March 24, 1882, at Iron Springs (present day Mescal Springs). Wyatt killed Curly Bill during the shoot out. In his journal written in October 1881, George Parsons referred to Brocius as "Arizona's most famous outlaw

Explanation:

Brocius is thought to have been born in 1845 and arrived in Arizona Territory from either Texas or Missouri in about 1878, bringing a herd of cattle to the San Carlos Reservation. Afterward, he made his way to Tombstone, Arizona where he was a vicious, drunken gunman, cattle rustler, and murderer.

In October of 1880, he shot Tombstone's first marshal, Fred White when the marshal attempted to disarm him. Charged with the murder, Brocius was later acquitted by a jury as an accidental death.

In July of 1881, Curly Bill, along with Johnny Ringo, killed William and Isaac Haslett in Hauchita, New Mexico in revenge for the deaths of Clanton members Bill Leonard and Harry Head who had attempted to rob the Haslett brothers general store some weeks earlier. A few weeks later, Brocious led an ambush attacking a group of Mexicans in the San Luis Pass, killing six of them and torturing the remaining eight.

After the death of "Old Man" Newton Clanton in another ambush in Guadelupe Canyon in July, Curly Bill became the leader of the Clanton Gang. After the Gunfight at the O. K. Corral in October 1881, Brocius attempted to kill Virgil Earp and succeeded in assassinating Morgan Earp. Brother Wyatt, looking for revenge for Morgan's killing, reportedly caught up with Brocius on March 24, 1882, and killed him with a double shotgun blast to the chest. This account; however, was reported by Wyatt Earp himself and many historians doubt the fact as Earp was known to have exaggerated some accounts.
