The case
On the evening of 18 September 1877 six men stopped an eastbound Union Pacific passenger train at Big Springs, Nebraska. In the express car they found a haul far larger than anything their stagecoach robberies had produced: about $60,000 in newly minted twenty-dollar gold pieces, shipped from the San Francisco mint. They took that, and $1,300 and four gold watches from the passengers, divided the coins and rode off in pairs. One of the pairs was a former Texas cowhand and racehorse man of twenty-six named Sam Bass.
Bass was born on a farm near Mitchell, Indiana, on 21 July 1851. Orphaned before he was thirteen, he spent several years in an uncle's house, left at eighteen, worked for most of a year in a Mississippi sawmill, and reached Denton, Texas, in 1870. He tried cowboy work, then tended horses at a hotel and worked for the county sheriff, William Egan, hauling freight and mending fences. In 1874 he acquired a fast mare that became known as the Denton Mare and left Egan's employ to race her. When the racing dried up in 1876 he and Joel Collins agreed to drive a small herd of longhorns north for their owners.
They sold the herd, paid the hands and found themselves holding $8,000 that belonged to ranchers back in Texas. Instead of returning it they gambled it away in Ogallala and in Deadwood, the gold town in the Black Hills. Freighting did not pay, so in 1877 they and a few hard companions began robbing stagecoaches on the Deadwood roads. Seven holdups brought in little. Big Springs, led by Collins, was their attempt at something bigger. Within weeks of it Collins and two others were dead, killed resisting arrest.
Bass made it back to Texas disguised as a farmer and gathered a new band around Denton. In the spring of 1878 they held up two stagecoaches and four trains within about twenty-five miles of Dallas. The takings were small, but the robberies stirred north Texas, and posses, Pinkerton men and a special company of Texas Rangers under Captain Junius Peak spent weeks chasing the gang across north Texas. Bass, who knew the country, kept slipping away.
What caught him was betrayal. Jim Murphy, a member of the gang, had come to an arrangement with the authorities and rode with Bass as their informer. As the gang rode south in July to rob a small bank at Round Rock, north of Austin, Murphy got word to Major John B. Jones, commander of the Rangers' Frontier Battalion, who moved men quietly into the town.
On Friday 19 July 1878 Bass, Seaborn Barnes and Frank Jackson rode into Round Rock to look the town over before the robbery. They went into Koppel's store to buy tobacco. Williamson County deputy A. W. Grimes, who did not know who they were, followed them in to ask if they were carrying pistols, and was shot dead. In the gunfight that spread into the street Barnes was killed and Bass was badly wounded. Jackson got him onto a horse and out of town.
The next morning a posse found Bass lying helpless in a pasture outside town and brought him back to Round Rock. He died on 21 July 1878, his twenty-seventh birthday, and was buried in the town cemetery. Frank Jackson was never caught.
The victims
Deputy Sheriff A. W. Grimes of Williamson County, known as Caige, walked into Koppel's store on 19 July 1878 to question three strangers about their sidearms and was shot dead before he could draw. Few people in Round Rock knew what the gang looked like, and Grimes did not know who the men were. A Travis County deputy, Maurice Moore, was wounded in the chest in the same exchange and survived. The gang's train and stage robberies killed no one, though their losses fell on the Union Pacific, express companies and the passengers whose watches and money were taken.

What the record settles, and what it doesn't
Established
- On 18 September 1877 a band including Sam Bass and led by Joel Collins robbed a Union Pacific train at Big Springs, Nebraska, of about $60,000 in new twenty-dollar gold pieces.
- Collins and two other members of the Big Springs band were killed within weeks while resisting arrest.
- In spring 1878 Bass's Texas gang robbed two stagecoaches and four trains near Dallas.
- Gang member Jim Murphy informed on Bass to Major John B. Jones of the Texas Rangers.
- Deputy A. W. Grimes was shot dead at Round Rock on 19 July 1878, and Seaborn Barnes was killed in the ensuing gunfight.
- Bass died of his wounds at Round Rock on 21 July 1878, his 27th birthday.
Disputed
- Who fired the shot that mortally wounded Bass is not settled; Rangers George Herold and Richard Ware are both credited in different accounts.
- Why Murphy turned informer is told in different ways, from a straightforward deal to escape prosecution to claims that pressure was put on him through his sick father.
- Where Bass was found, north or west of Round Rock, varies between accounts.
- No photograph has been confirmed to show Bass; his sister reportedly said the picture on a wanted poster was not him.

Afterwards
Bass was buried in Round Rock. A year later his sister visited to place a better headstone, which souvenir hunters gradually chipped away; a replacement now stands and what is left of the original is kept at the town's public library. Major Jones died in 1881.
Bass soon became the subject of cowboy song and story, and the ballad sung about him turned a gambler who spent ranchers' money and robbed trains into a generous young rider undone by a traitor. Round Rock has kept him as a local character. The record is plainer: a series of mostly unprofitable robberies, one large lucky haul, and a deputy killed in a country store.
