On July 5, 1943, just hours after Fourth of July celebrations had ended, the residents of Boise City, Oklahoma woke to the sound of explosions. Bombs were falling from the sky, and in the chaos, terrified citizens assumed the worst—that America was under attack. What they didn't know was that the bombs raining down on their tiny Panhandle town weren't coming from Germany or Japan. They were coming from the United States Army.

A B-17 Flying Fortress crew from Dalhart Army Air Base in Texas had departed on a routine night training mission, headed for a practice bombing range in nearby Conlen, Texas. But the navigator, Second Lieutenant John M. Daly, got catastrophically lost. In the darkness of the Oklahoma Panhandle, he spotted four lights arranged in a pattern and assumed he'd found his target. He was 43 miles off course. Those lights belonged to the Cimarron County courthouse square.

Over the next thirty minutes, six 100-pound practice bombs fell on Boise City—the only time in American history that the continental United States was bombed by its own military forces. The bombs struck near a garage, a Baptist church, and several locations around the town square. And yet, miraculously, not a single person was killed or seriously injured.

This is the story of an extraordinary night in a tiny Oklahoma town—a story of wartime confusion, terrified civilians, and a community that responded to catastrophe with something America often forgets is possible: grace.

Section 2: Timeline of Events

The accidental bombing of Boise City occurred during a pivotal year of World War II, when military training operations had transformed the American Southwest into a landscape of air bases and practice ranges.

Key Dates:

Spring 1943: Dalhart Army Air Base established in Texas, 45 miles south of Boise City, to train B-17 Flying Fortress crews for the European Theater

July 4, 1943: Boise City celebrates Independence Day; Fourth of July festivities conclude late evening

July 5, 1943, 12:30 AM: First bomb strikes near Forrest Bourk's garage off the courthouse square

July 5, 1943, 12:30-1:00 AM: Five additional bombs fall over 30 minutes; residents initially believe town is under enemy attack

July 5, 1943 (morning): Sheriff discovers bomb casing stamped "U.S. ARMY"; Dalhart Army Air Base confirms error

50th Anniversary (1993): B-17 crew invited back to Boise City; all decline, though radio operator sends audio tape for celebration

Section 3: Historical Significance

The Boise City bombing stands as a remarkable example of how ordinary Americans responded to extraordinary circumstances during wartime. Rather than demanding court-martials or pursuing legal action, the community chose pragmatism and grace. The Army apologized, paid for all damages, and the town moved on—understanding that accidents happen in war, even on home soil.

The incident also reveals the human cost of wartime training operations that history often overlooks. While B-17 crews were preparing to fly dangerous missions over Nazi-occupied Europe, mistakes could—and did—happen. Navigator John M. Daly's error ended his aviation career that morning, but the rest of his crew continued training and eventually flew combat missions over Germany.

Today, the bombing serves as a reminder that patriotism during World War II wasn't just about fighting overseas—it was about communities like Boise City extending grace to the young men learning to fight that war, even when their training literally hit too close to home.

In February 1849, an enslaved sawmill worker named Appling approached his owner with an extraordinary proposal: he would murder Martin Posey's wife Matilda in exchange for a promise of freedom. What followed exposed the brutal mechanics of what historians call "criminal bargains"—informal contracts between enslavers and enslaved people that the legal system barely acknowledged.

Martin Posey, a man of modest origins who married into the wealthy Holmes family, had earned the nickname "The Devil of Montmorenci." Contemporary accounts describe him as having "quite the thirst for power and money, coupled with his inconsideration for everyone but himself." When his father-in-law died in 1847, Posey gained control of Matilda's inheritance through South Carolina's coverture laws. But he wanted more—specifically, he wanted Matilda's teenage sister Eliza and her portion of the Holmes estate.

The murder occurred on a Friday afternoon in February 1849. Matilda was last seen directing workers on the plantation before Martin asked her to check on the dairy door. There, Appling waited. He bludgeoned her to death while Martin, according to trial evidence, "encouraged him from behind." They buried her body in a shallow grave near a spring.

But the "deal" was always a lie. Roughly one month later, workers discovered Appling's decomposing body in neighboring Abbeville County. The coroner's findings revealed death by gunshot—but it was one detail that transformed everything: Appling's hands were still tied together. Martin Posey had simply erased the witness to his crime.

Timeline of Events

-The Martin Posey case unfolded in "Bloody Edgefield," a South Carolina town where 39 percent of all prosecutions involved violent offenses—the highest rate in the state. Violence wasn't exceptional here; it was routine. Historians have called it "the Deadwood of its day."

-1847: Matilda's father dies; his estate is divided among his children

-February 1849: Appling murders Matilda; she is buried in a shallow grave

-Approximately one week later: Searchers discover Matilda's body

-March 1849: Workers find Appling's body with tied hands in Abbeville County

-October 10, 1849: Four-day trial begins at Edgefield County Court House

-October 14, 1849: Jury returns guilty verdicts on both murder counts

-February 10, 1850: Martin Posey executed by hanging

Historical Significance

The Posey case illuminates the impossible position of enslaved people within antebellum legal systems. South Carolina's Negro Act of 1740 prohibited enslaved people from giving sworn testimony in court, especially against white defendants. Any promise Martin Posey made to Appling existed in a legal void—unenforceable, unwitnessable, and ultimately worthless.

Scholars studying this case note that Appling was "neither passively acquiescent nor docile" but entrepreneurial. He demonstrated what historians call "slave agency"—the capacity to negotiate even within brutal constraints. Lacking conventional bargaining chips like money or property, he weaponized the only thing he had: his willingness to commit violence.

The execution drew between 4,000 and 5,000 spectators—more than ten times the village population. The Edgefield Advertiser reported it was a spectacle "which even the oldest inhabitants could not recollect" for its size. That afternoon, the town square descended into what newspapers called "drunken brawls"—violence so normalized that even an execution couldn't proceed without it.
