Early life and Civil War

Chaffee was born in Orwell, Ohio. When the American Civil War broke out in July 1861, Chaffee enlisted in the Union Army as a private in the U.S. 6th Cavalry Regiment. In 1862, Chaffee was promoted to sergeant and took part in the Peninsular Campaign and the Battle of Antietam. In September of that year he was made the first sergeant of Company K. He was commissioned as a second lieutenant in May 1863. His 6th Cavalry, on detached service from General John Buford's 1st Union Cavalry Division, though outnumbered attacked a Confederate Cavalry regiment at Fairfield, Pennsylvania, just outside Gettysburg on July 3, 1863 (source, Wittenberg, Eric: Gettysburg: Forgotten Cavalry Actions). In the ensuing action he was wounded and briefly held a prisoner of the Confederates. He served with the 6th Cavalry for the remainder of the war, being twice wounded. In February 1865, he was promoted to first lieutenant. For his "gallant and meritorious" actions in the Battle of Dinwiddie Court House he was brevetted captain.

After the war, Chaffee became a member of the Military Order of the Loyal Legion of the United States.

Indian Wars

Chaffee decided to remain with the army after the war. He was posted to the western frontier, and was promoted to captain of Regulars in October 1867. For the next thirty years he served in the Indian Wars, fighting the Central Plains and Southwestern tribes. In 1868, he was brevetted major for his actions at Paint Creek, Texas. In the following years he engaged the Indians many times, most notably at Red River, Texas, in 1874, and Big Dry Wash, Arizona, in 1882, for which he was brevetted lieutenant colonel.

In July 1888 he was promoted to major and transferred to the 9th Cavalry. From 1894 to 1896, he was an instructor of tactics at the Army's Infantry and Cavalry School at Fort Leavenworth. In June 1897 he was promoted to colonel and transferred to the 3rd Cavalry, where he served as commandant of the Cavalry School at Fort Riley until 1898.

Spanish–American War

With the outbreak of the Spanish–American War in 1898, Chaffee was assigned a brigade and was promoted to brigadier general of volunteers in May of that year, and in July after the victory at El Caney, to major general of volunteers. From late 1898 to May 1900, he served as the chief of staff to the military governor of Cuba, General Leonard Wood, being promoted to colonel of regulars in May 1899. He was a member of Society of the Army of Santiago, a military society for officers who had served in Cuba.

Boxer Rebellion

In June 1900, the Boxer Rebellion broke out in China. Chaffee was sent to China in July as the commander of the U.S. Army's China Relief Expedition. The Expedition was a part of the international force sent to rescue Western citizens and put down the rebellion. Chaffee participated in the Gaselee Expedition and subsequently the Battle of Peking, in which the legations were relieved.

Chaffee was one of the founders of the Military Order of the Dragon, a military society for officers who had served in China during the Boxer Rebellion. He served as the society's president from its founding in 1900 until his death.

Later military service

In February 1901, he was promoted to major general in the Regular Army. From July of that year until October 1902, he served as the military governor of the Philippines. This included the beginning of the second phase of the Philippine-American War. In October 1902, he became commander of the Department of the East, a position he held until October 1903.

In January 1904, he was promoted to lieutenant general and, from January 9, 1904, until January 14, 1906, served as the Chief of Staff of the United States Army. At his own request, he was retired on February 1, 1906.

General Chaffee was invested with the Grand Cross of the Legion of Honor by the president of France.

In his retirement, he moved to Los Angeles, where he was appointed president of the Board of Public Works for the city of Los Angeles.


Chaffee was married twice; in September 1867 he married Kate Haynie Reynolds, a young widow who died two and a half years later.

In 1875, he married Annie Frances Rockwell. Their son Adna R. Chaffee Jr. also became a general and was one of the fathers of the U.S. Army's armored forces, having a light tank, the M24 Chaffee, named in his honor.
