David Addison Weisiger was born on December 23, 1818, at "The Grove," in Chesterfield County, Virginia. During the war with Mexico he served as 2nd lieutenant of Company E, 1st Virginia Volunteers. Afterwards he entered business in Petersburg. As a captain of Virginia militia he was officer of the day at the hanging of John Brown in 1859. Two years later, as a major of the 4th Virginia Battalion Militia, he was on duty at Norfolk. Entering the Confederate Army as colonel of the 12th Virginia Infantry, on May 9, 1861, he served on the lower Peninsula until the spring of 1862, when his regiment was attached to the Army of Northern Virginia in General William Mahone's brigade. With this command he fought at Seven Pines, during the Seven Days battles, and at Second Manassas, where he was dangerously wounded and disabled until the following July. At the Wilderness, on May 6, 1864, he succeeded Mahone in command of the brigade, and was commissioned brigadier with temporary rank from May 31. Subsequently he was placed on the permanent list to date from July 30. This was a recognition of his distinguished services at the battle of the Crater, where he and Mahone led the Confederate counterattack and were largely responsible for the complete victory that followed. He was again wounded in this battle. Paroled at Appomattox on April 9, 1865, General Weisiger returned to Petersburg and became cashier of a bank. He later engaged in business in Richmond, and died there on February 23, 1899. He is buried in Petersburg.
