Question: Which Confederate general Goggin served under was the oldest? Passage:In 1861, Goggin moved back to Virginia, entering the Confederate States Army on July 1, 1861 as a major in the 32nd Virginia Volunteer Infantry Regiment where he was assigned to lead a battalion. Goggin and the 32nd Virginia Infantry served under Maj. Gen. John B. Magruder in 1861 and into 1862 during the Peninsula Campaign. Goggin joined the First Corps, Army of Northern Virginia in April 1862, serving on the staff of Maj. Gen. Lafayette McLaws as his assistant adjutant general. He served in this capacity during all of the First Corps' engagements, in both the Army of Northern Virginia and the Army of Tennessee, until the spring of 1864. During the Battle of Fort Sanders in November 1863, Goggin carried a message from McLaws to Lt. Gen. James Longstreet, informing him that the attack was beginning to fail and it was futile to carry in on. When McLaws was replaced with Maj. Gen. Joseph B. Kershaw in May 1864, Goggin served as his assistant adjutant general as well. His service in this post was highly praised by Goggin's superiors.
