Launching Site of First U.S. Army Warplane
Brownsville, Cameron County, Texas
Marker Inscription
From Old Fort Brown Cavalry Drill Field, near this spot, was made the first flight of a U.S. Army plane to be fired upon in armed hostilities, April 20, 1915. Two Signal Corps officers, Lts. Byron Q. Jones and Thos. Milling, flew a Martin T.O. Curtiss 75 on the border to spot movements of Mexican revolutionist Pancho Villa. They reached 2,600 feet; were up 20 minutes. Though they did not cross the Rio Grande, the plane was hit by machine gun and small arms fire. Their patrols lasted 6 weeks. Planes were used more effectively in fighting against Villa in 1916.

The Story
In the spring of 1915, as revolutionary turmoil spilled across the Rio Grande, the U.S. Army was just beginning to imagine what airplanes might do in war. From the old cavalry drill field at Fort Brown, two Signal Corps aviators took a fragile Curtiss biplane aloft to scout the movements of Pancho Villa's forces along the border. When ground fire struck their machine, it marked the first time an American military aircraft came under fire in hostilities—a small, dangerous milestone in the birth of American air power.
Why it matters
This border patrol flight stands at the very threshold of U.S. military aviation, foreshadowing how aircraft would soon reshape reconnaissance and warfare for the American century to come.
The story behind this marker
AI contextThe era
In the spring of 1915, the Mexican Revolution had been going on for nearly five years. Rival factions were fighting for control of Mexico, and the long border with Texas felt the consequences. Refugees crossed north, fighting sometimes happened within sight of American towns, and the U.S. Army was sent to watch the Rio Grande. One of the most prominent revolutionary leaders was Francisco "Pancho" Villa, whose forces were a major presence in northern Mexico.
Military aviation was brand new at the time. The Wright brothers had flown only about a decade earlier, and the U.S. Army's aviation arm was a small unit inside the Signal Corps with a handful of aircraft and pilots. In Europe, the First World War had begun the year before and was already showing that airplanes could change how armies watched their enemies.
Fort Brown, at Brownsville, had guarded the lower Rio Grande since the U.S.-Mexican War of 1846, when American troops first built a fort here. Its old cavalry drill field, laid out for horses, was about to launch a very different kind of scout.
People & events
On April 20, 1915, two Signal Corps officers, Lieutenants Byron Q. Jones and Thomas Milling, took off from the Fort Brown drill field in a fragile biplane. Their job was reconnaissance: spot the movements of Villa's forces along the border and report back. The marker records that they reached 2,600 feet and stayed up about twenty minutes.
They never crossed the Rio Grande, but that didn't protect them. Machine gun and small arms fire from below hit their plane. That made it the first U.S. Army aircraft to be fired on in armed hostilities, a distinction no one would have wanted but everyone who followed would inherit. Both men were early Army aviators at a time when the entire corps of military pilots could have fit in a single room.
The border patrols continued for about six weeks. The next year, after Villa's forces attacked Columbus, New Mexico, in March 1916, the United States sent a punitive expedition into Mexico, and Army aircraft went along. As the marker notes, planes were used more effectively in that later campaign against Villa. That was a step toward treating aviation as a working part of the Army instead of an experiment.
Its place in the American story
This short flight marks the start of American military aviation's combat history. Within a few years, American pilots would be flying over the Western Front. Within a few decades, air power would decide wars. Every later chapter starts with small, vulnerable machines like the one that left this drill field.
The flight also shows how closely the Mexican Revolution and the U.S. borderlands were tied together. The same border troubles that brought aircraft to Brownsville led to the 1916 expedition. The Army came away from that campaign with a sharp sense of how much it still had to learn about machines, supply and aviation before entering the World War.
It is also a reminder that great technological change often begins modestly. Two lieutenants spent twenty minutes at 2,600 feet, came back with bullet holes, and gave the first answer to a question the whole century would keep asking: what could an airplane do in war?
If you visit
Stand near the marker and look at the open sky over the lower Rio Grande. Picture a canvas-and-wire biplane climbing slowly from a field meant for cavalry horses, with the river and the Mexican bank spread out below. The contrast between the horse soldiers of Fort Brown and that flying machine is the heart of this site.
Brownsville is full of layered history. The Fort Brown area links this 1915 flight to the U.S.-Mexican War decades earlier, and the wider region holds Civil War and border stories as well. It's a good place to spend a day tracing how the Rio Grande shaped American history over more than a century.
If you're traveling the southern tip of Texas, add this stop to a route that includes the Gulf Coast and the river valley. It's a quick visit, but it's one of the few places where you can stand at the very beginning of American air power.

Post Hospital
Brownsville, TX
When Captain William Alonzo Wainwright arrived in Brownsville in 1868 to rebuild Fort Brown after the Civil War and an 1867 hurricane, one of his first projects was this Post Hospital, completed in 1869 and admired for its classical, Palladian-influenced design. Beyond its architecture, the building holds a place in medical history: First Lt. William C. Gorgas, later famous for controlling yellow fever during the building of the Panama Canal, began the studies that shaped that work while stationed here in 1883.
Post Hospital Annex
Brownsville, TX
Completed in 1869 as Captain William Alonzo Wainwright rebuilt Fort Brown after the Civil War, the Post Hospital Annex — also known as the Medical Laboratory — was built to house personnel working in the adjacent Post Hospital. A finely crafted, classically influenced building, it later served in turn as a medical laboratory, a storehouse, and a dispensary.
Fort Brown, Buildings 85 and 86
Brownsville, TX
These two 1867 brick buildings at Fort Brown once served as the post's morgue and linen storage. Here Dr. William C. Gorgas and fellow officers carried out autopsies in a study of yellow fever, pressing on with the dangerous research despite a superior officer's orders to stop. Gorgas survived the disease and gained immunity—experience that shaped a career later famous for conquering yellow fever during the building of the Panama Canal.
Fort Brown Commissary/Guardhouse
Brownsville, TX
Built in 1905 as a food storage facility, this Fort Brown building was abandoned within a year when the post first closed, then pressed back into service as a guardhouse and jail when the army reactivated the fort during the Mexican border troubles. Among those held here were political refugees who fled across the river after the Battle of Matamoros on June 4, 1913. Its loading dock and dormered shed roof still mark its dual life as commissary and lockup.
