Gunmen behind a boulder hit Wham's paymaster convoy; eight Buffalo Soldiers wounded, $28,345 gone
At about 1:00 pm on May 11, 1889, Frankie Campbell was trying to guide her horse around a boulder blocking a narrow Arizona gorge when the shooting started. The boulder had been placed there deliberately. From breastworks above the road — some rifle barrels made of yucca stalks — more than a dozen gunmen opened fire on Major Joseph Wham's Army paymaster convoy and its eleven-man Buffalo Soldier escort. Eight soldiers were wounded, the $28,345 payroll was stolen, and the money was never recovered. The men almost certainly responsible were acquitted at trial four months later.
The robbery produced two Medal of Honor recipients — Sergeant Benjamin Brown and Corporal Isaiah Mays — from a unit that couldn't get a fair hearing in court. The trial exposed how frontier juries weighted the testimony of Black soldiers against the word of white community members, and how racial bias, anti-federal sentiment, and Mormon grievances over the Edmunds Act combined to shield the likely perpetrators. It remains one of the clearest documented cases of a Medal of Honor action immediately followed by a failed justice system.
QWhat did Frankie Campbell do during the thirty-minute gunfight that made her an essential witness — and why had Wham arrested her immediately afterward?
Campbell had been riding ahead of the convoy when her horse spooked at the first shots, threw her, and bolted back toward the stagecoach station. She crawled behind a bush and rocks about fifty feet past the disabled ambulance and watched the entire battle from there — close enough that the bandits called her by name and fired a few rounds in her direction before turning back to the soldiers. Major Wham, suspicious of how the bandits knew her name, arrested her at the scene before she had finished giving first aid to the wounded. She was released shortly after and became one of the prosecution's most important witnesses at trial, offering the clearest account of what happened on the ridge.
QWhy did one of the accused bandits start charging admission to see himself in jail while waiting for his alibi to be confirmed?
William Ellison 'Cyclone Bill' Beck had been arrested partly because local folklore held that one bandit had disguised himself to resemble Beck during the robbery — a detail that made him notorious enough to draw curious visitors to the Tucson jail where he was being held. Beck, waiting for his alibi to come through, decided to capitalize on the attention. He began charging a fee for what he called viewings of 'the raw head and bloody bones of the Gila Valley' and claimed he could make enough money from the spectacle to cover all his trial expenses. His alibi was confirmed and he was released without charges — having apparently turned his own wrongful detention into a modest source of income.
QHow did a misunderstanding of the jury instructions likely contribute to the acquittal of all eight defendants?
After the two-hour deliberation and the not-guilty verdict shocked observers, the jury issued a public statement insisting they had heard everything presented at trial and saw no reason to stay in the room longer. What emerged afterward was a different explanation: the jurors apparently believed the instructions required them to find all eight defendants guilty as a group or acquit all eight. Since they could not agree that every single defendant was personally involved in the robbery, they concluded they were obligated to return a not-guilty verdict across the board. Deputy William Breakenridge, who had worked the case, was blunter about the other factor: too many jurors simply did not believe it was a serious crime to rob a federal government payroll destined for Black soldiers.
