His father and uncle published newspapers in Terre Haute and then in Indianapolis, including Indiana State Sentinel, a pro-democratic newspaper. Chapman later studied at Marion County Seminary.
In 1847 Chapman was appointed to the U. S. Navy as a midshipman. He served on the frigates USS Cumberland and USS Constitution until 1850, when he resigned following the death of his uncle.

From 1854–55, he edited and published his own newspaper called the Indiana Republican. He became the assistant clerk to the U.S. House of Representatives in 1860.

## Civil War service

At the beginning of the American Civil War in 1861, he resigned his clerk position to volunteer in the Union Army. On November 2 he was commissioned a major in the 3rd Indiana Cavalry. Chapman briefly led the cavalry division of the Army of the Ohio in May of the following year. Transferring to the infantry, he commanded a brigade in the Army of the Potomac until June 27, 1862.
Chapman was promoted to lieutenant colonel on October 25, 1862.

Returning to the cavalry service, Chapman led his regiment during the Battle of Gettysburg in July 1863. Here his command was part of Col. Thomas C. Devin's brigade, and was noted as the first Union soldiers to engage Confederate forces approaching Gettysburg via the Cashtown road. Shortly after the battle, Chapman was given brigade command in the cavalry of the Army of the Potomac until March 1864.
Chapman participated in the Valley Campaigns of 1864 against Confederate Lt. Gen. Jubal Early's forces, lasting from May to October. He was promoted to the rank of brigadier general on July 21, 1864, to rank from that date.

Chapman had with him now three small regiments and a few artillery pieces to hold the Valley. Beginning on April 19, 1865, he was given command of the cavalry division assigned to Washington, D.C. In recognition of his performance at Winchester in September 1864, on January 13, 1866, President Andrew Johnson nominated Chapman for appointment to the grade of brevet major general of volunteers, to rank from March 13, 1865, and the United States Senate confirmed the appointment on March 12, 1866.
