Donald C. Pfanz, "Ewell, Richard Stoddert," American National Biography Online, February 2000, http://www.anb.org/articles/04/04-00353.html.
Ewell was on leave at his family home in Virginia, recovering from a near-fatal bout of malaria, when he learned that the state had seceded from the Union. Although opposed to secession, he promptly resigned from the U.S. Army and accepted a lieutenant colonel's commission in the Confederate army. On 1 June 1861 U.S. troops attacked his command at Fairfax Court House. Ewell was slightly wounded in the skirmish, making him perhaps the first southern field-grade officer to be wounded in the war. Perhaps in part because of his injury, he was promoted to brigadier general on 17 June.
