Edward Tiffin Harrison Warren (June 19, 1829 – May 5, 1864) commanded a Virginia infantry regiment and occasionally held interim brigade command in the Army of Northern Virginia during the American Civil War.
Warren was born in Harrisonburg, Virginia, where he practiced law before the war. He married Virginia Magruder, known as Jennie, in 1855. They lived, beginning in 1856, at what is now the E.T.Warren-Sipe House. (The house served as a hospital following the Gettysburg Campaign. Joseph W. Latimer, the "boy major," a Confederate artillerist, died there on August 1, 1863.) Their son, James Magruder Warren, became a prominent local physician in the late nineteenth century.
Edward Warren became a lieutenant in the Valley Guards, a local militia company. In that role, he attended the trial and execution of John Brown in 1859. He was elected to the town council the next year but resigned after the outbreak of war.
The Valley Guards were incorporated into the 10th Virginia Infantry after the war began. Warren was commissioned lieutenant colonel of the 10th Virginia on August 1, 1861. As lieutenant colonel, Warren served at the First Battle of Bull Run, where the regiment served in the brigade of Brig. Gen. Edmund Kirby Smith. He became colonel on May 8, 1862, after Colonel Simeon B. Gibbons was killed at the Battle of McDowell in May 1862.
The 10th Virginia served under Stonewall Jackson in Jackson's Valley Campaign. At the First Battle of Winchester on May 25, 1862, Warren took his regiment to Brig. Gen. Richard Taylor's left flank to support his attack on the Union left. He was serving at the time under Col. Samuel V. Fulkerson in the absence of ailing Brig. Gen. William B. Taliaferro. Under Taliaferro's command, Warren's regiment also helped stop Col. Samuel S. Carroll's raid on Port Republic prior to the Battle of Port Republic on June 9, 1862.
