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.

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.
