William Edward Birkhimer

Twelve Men Charged Three Hundred at San Miguel

William Edward Birkhimer was born on March 1, 1848, in Somerset, Perry County, Ohio. His military life began while he was still a teenager, during the final phase of the American Civil War. He entered Union service as a private in the 4th Iowa Cavalry in 1864, beginning a remarkable career that would eventually carry him from the enlisted ranks to brigadier general.

After the Civil War, Birkhimer chose to remain connected to military service. In 1866 he entered the United States Military Academy at West Point. He graduated in 1870 and was commissioned a Second Lieutenant in the 3rd U.S. Artillery. His early Regular Army assignments included garrison duty at Fort Pulaski in Georgia, Fort Monroe in Virginia, and Fort Hamilton in New York. These years gave him both practical artillery experience and the professional education expected of a career Army officer.

Birkhimer later returned to West Point as an instructor, serving in academic and artillery-related roles during the 1870s. He was promoted to First Lieutenant in 1879 and continued developing a career that combined field service, military administration, law, and scholarship. From 1886 to 1890 he served as Judge Advocate for the Department of the Columbia, an assignment that deepened his involvement with military law.

His interest in law became one of the defining features of his professional life. He studied law and produced several important works on military administration and legal authority. His best-known book, Military Government and Martial Law, first appeared in 1892 and was later revised and expanded. The work examined military occupation, martial law, the authority of commanders, and the relationship between military and civil government. It became an important part of his legacy beyond the battlefield.

On February 10, 1898, Birkhimer was promoted to Captain in the 3rd U.S. Artillery. That year the United States went to war with Spain, and he soon departed for the Philippine Islands in command of a battalion drawn from the 3rd Artillery. He participated in the military operations surrounding Manila, including the assault and capture of the city in August 1898.

The end of the Spanish-American War did not bring peace to the Philippines. Fighting between American forces and Filipino troops developed into the Philippine-American War, and Birkhimer remained on active service in Luzon. By early 1899 he was participating in operations beyond Manila as American forces advanced against organized Filipino resistance.

His most famous action came on May 13, 1899, at San Miguel de Mayumo on the island of Luzon. Birkhimer was serving as a Captain in the 3rd U.S. Artillery when he confronted an enemy force far larger than the small group immediately under his leadership.

The official description of the action is brief but extraordinary. With only twelve men, Birkhimer charged and routed approximately three hundred of the enemy. The citation does not provide elaborate battlefield dialogue or a long reconstruction of the engagement, but its few words reveal the scale of the risk. A small group under his leadership attacked a force many times its size and succeeded in driving it from the position.

That action at San Miguel de Mayumo became the defining moment of Birkhimer’s combat career. It demonstrated aggressive leadership at close quarters and the willingness to act decisively despite a severe numerical disadvantage. More than three years later, on July 15, 1902, he received the Medal of Honor for the gallantry he had displayed that day.

The recognition came after Birkhimer had already advanced to greater responsibility. On July 5, 1899, less than two months after the San Miguel action, he was appointed Colonel of the 28th United States Volunteer Infantry. He continued serving in the field against Filipino forces and remained with the volunteer regiment until he was mustered out in 1901.

Birkhimer then returned fully to the Regular Army. He was promoted to Major in the Artillery Corps in August 1901. His assignments in the following years included artillery inspection and staff responsibilities in the Department of California. In May 1905 he became a Lieutenant Colonel in the Artillery Corps and later served as president of the Artillery Board at Fort Monroe.

His long military career reached its highest formal rank on February 15, 1906, when he was promoted to Brigadier General in the United States Army. He retired the following day at his own request after more than four decades connected with military service. The progression was exceptional: he had begun as a teenage private during the Civil War and ended his Army career as a general officer.

Retirement did not erase his influence as a military scholar. Birkhimer continued to be associated with the study of military government and martial law, subjects on which his professional experience had given him unusual authority. Later editions of his principal work continued to develop the legal questions surrounding military occupation, command authority, civil institutions, and the use of military power.

His career therefore occupied two distinct but closely connected worlds. In one, he was a combat officer whose leadership at San Miguel de Mayumo earned the Medal of Honor. In the other, he was an officer-scholar who examined the legal principles governing armies, commanders, occupied territories, and civil authority. Few careers combined battlefield gallantry, senior command, military law, and published scholarship in the same way.

William Edward Birkhimer died in Washington, D.C., on June 10, 1914, at the age of sixty-six. He was buried at Arlington National Cemetery in Virginia.

His military journey had stretched across half a century of profound change in the United States Army. He entered service as an enlisted cavalryman during the Civil War, became a West Point graduate and artillery officer, served in the Philippines, commanded volunteer infantry, received the Medal of Honor, and ultimately retired as a Brigadier General. Yet among all those achievements, the moment at San Miguel remains the most dramatic: a captain with twelve men charging a force of three hundred and emerging victorious.
