In Wyoming, a thousand Cheyenne warriors attack the immigrant transport link at Platte Bridge

-
Following the massacre at Sand Creek, Cheyenne rage forged alliances and an effective force of more than two thousand mounted warriors. They had launched a series of attacks in Colorado, burning out ranches and even attacking smaller towns. They made an assault on the garrison at Platte Bridge, Wyoming, an important link on the immigrant trail.  Beaten off, the next day they attacked and wiped out a military wagon train approaching the fort.  Troop losses were 28 killed.  Cheyenne losses were not accurately counted.  (By John Osborne)
