Fagan fought in the Camden Expedition, including the successful destruction of a Federal supply train at the Battle of Marks' Mills, which led to the Federal retreat from southern Arkansas. In recognition for his service in the Camden Expedition, he was promoted to major-general on April 24, 1864, and commanded the Arkansas division of Confederate cavalry during Price's Missouri Expedition. His division broke in a "disgraceful manner" during the failed assault on Fort Davidson at Pilot Knob, Missouri.[2] During Price's withdrawal from Missouri and Kansas, Fagan and John S. Marmaduke's divisions were overwhelmed at the Battle of Mine Creek. The end of the war found Fagan in command of the District of Arkansas of the Trans-Mississippi Department, which was active militarily until late April 1865.[1]
Later life
Fagan was paroled by United States military authorities on June 20, 1865. After his parole, he returned to his farm to make a living. Fagan commanded Joseph Brooks' militia forces during the so-called Brooks-Baxter War of 1874, despite Fagan's former service as a Confederate States Army general.[citation needed]
He served as a receiver for the United States Land Office in 1877. In 1890, Fagan ran for the office of state railroad commissioner but was defeated.[1] He died of malaria in Little Rock, Arkansas, and was buried at the historic Mount Holly Cemetery in that city.
Personal life
Fagan's first wife was the sister of Confederate States Army general William N. R. Beall. He was also related by marriage to Arkansas governor Henry M. Rector.
