Taliaferro became commander of Virginia's state militia following Virginia's secession action on April 17, 1861; indeed, in what might be Virginia's 1st act of aggression of the war, on April 18, 1861, Virginia State Militia Major General Taliaferro was sent to take command at
Norfolk, Virginia. Later he took command of the
23rd Virginia Infantry as a colonel. He fought several engagements in 1861 and by the end of the year had ascended to brigade command, where he led Confederate forces at the
Battle of Greenbrier River, in what is now
West Virginia. He served with
Thomas J. "Stonewall" Jackson through the Valley Campaign and the
Seven Days Battles. After Brig. Gen.
Charles Sidney Winder was killed at
Cedar Mountain, Taliaferro took over command of the Stonewall Division. He led it for the next three weeks, but at Brawner's Farm on August 28, 1862, he was badly wounded. Taliaferro spent the next few months recuperating and resumed division command just before the
Battle of Fredericksburg in December. Taliaferro was a strict and aloof commander who alienated many of his troops. There is at least one known circumstance when one of his troops actually assaulted him, though Taliaferro was unscathed. Taliaferro chafed under the command of General Jackson, complaining to his political colleagues in Virginia about Jackson's tactics and treatment of the men. Jackson later protested Taliaferro's promotion to brigadier general, while Taliaferro was still under Jackson's command; however, Jackson respected Taliaferro's leadership and military ability and did not continue to stand in his way. Jackson later would select Taliaferro for temporary divisional command in specific engagements. After Fredericksburg, Taliaferro was given command of the District of
Savannah. In this capacity he led troops at the
Battle of Fort Wagner on
Morris Island, a battle which is depicted in the movie
Glory. Taliaferro was commended for his service in that battle. In 1864, Taliaferro was given command of all forces in the Eastern District of
Florida, which made him the overall commander at the
Battle of Olustee that February. He subsequently returned to South Carolina, where he was made commander of all forces in that state. Taliaferro was still in command when Maj. Gen.
William T. Sherman entered the state from Savannah. ==Postbellum career==
