Guy V. Henry graduated from the United States Military Academy in May 1861, serving as a Union officer in the Civil War, and later in conflicts against the Native Americans in the West and southwest of the United States of America.
From May 25, 1891 to October 3, 1894, while commanding the 7th Cavalry Regiment, he was also commander of Fort Myer, Virginia. During the Spanish–American War, he was dispatched to Guantánamo, Cuba, and later sent to Puerto Rico, alongside General Nelson Miles. He received successive brevets for gallantry in various battles and was brevetted brigadier general, United States Army, for gallantry at the Battle of Rosebud in Montana Territory, where he was shot through the face while fighting Native Americans.
During the invasion of Puerto Rico, Henry led a "Provisional Division" from the city of Ponce to Arecibo, Puerto Rico to rendezvous with General Theodore Schwan, who was arriving from the city of Mayagüez.
The tropical rain impeded his trek and before he reached Mayagüez, the conflict was over. On December 6, 1898, he was designated Governor of Puerto Rico.
On February 6, 1899, he dissolved the Cabinet of Puerto Rico, which was instituted with the Autonomic Charter. Henry also eliminated taxes on basic food items.
On May 9, 1899, he was replaced by General George West. Davis.
Henry died of pneumonia in New York City and was buried in Section 2 of Arlington National Cemetery.
