Assault on Petersburg In the pre-dawn hours of June 17, the divisions of the IX Corps formed up for an assault on the entrenched Confederate position outside Petersburg. Barnes of the 29th had been elevated to command of the 2nd Brigade, 1st Division of the IX Corps, to which the 29th belonged.
Major Charles Chipman was placed in command of the 29th in his stead. While other divisions of the IX Corps attacked and were repulsed, the 1st Division moved to its assigned position in the late afternoon and lay down, studying the Confederate breastworks and awaiting orders to advance. At first, the division, to its relief, received orders that the attack had been called off. A short time later, however, came the order to attack. The division, including the 29th, charged from their protected position in a ravine out into an open plain in front of the Confederate entrenchments. According to the regimental historian, "They had scarcely emerged upon the open plain, when the whole crest of the Confederate works was fringed with fire and smoke; grape, canister, and musketballs filled the air." During this charge, the
color-bearer of the 29th, Sgt. Silas Grosvenor, was shot through the head. The colors were picked up by Sgt. John A. Tighe who was also killed.
Sergeant Major William F. Willis picked up the flag and became the third color-bearer killed in the charge. At this point, the 29th was forced to pause in its advance and retired a short distance. In the confusion, the colors were left on the field. Major Chipman asked for two volunteers to go with him onto the open ground to retrieve the colors. The three found the colors and, according to the regimental historian, the Confederates, admiring the bravery of the trio, did not fire and allowed them to return to their lines. The 1st Division of the IX Corps eventually captured the Confederate works in their front, however little had been accomplished by the
assault on Petersburg overall. The Confederates remained strongly entrenched and the long
siege of Petersburg began. The 29th, numbering just 100 men at this time, lost six killed and 23 wounded.
Battle of the Crater The 29th occupied trenches outside Petersburg with the rest of the Army of the Potomac during the summer of 1864. In July, Union troops dug a mine beneath the Confederate position and, on July 30, 1864, a massive amount of gunpowder was detonated in the mine, blasting a hole in the Confederate position. During the resulting
Battle of the Crater, the 1st Division of the IX Corps led a confused and failed attack. The 29th took part, charging into the crater with other regiments and eventually retreating, losing three killed, seven wounded and six captured.
Battle of Fort Stedman The 29th played a minor role in the
Battle of Globe Tavern, a movement intended to tighten the siege around Petersburg, on August 18, 1864. The regiment suffered only a few casualties during this engagement. In the fall of 1864, the 29th served uneventful duty along the Petersburg siege lines and was eventually, in November, assigned a garrison post in Battery 11, a small, unfinished
ravelin (detached fortification) outside of
Fort Stedman. Stedman was one of many earthen fortifications built along Union lines during the siege, and was only 150 yards from the Confederate trenches—the narrowest distance between the two armies. They would remain at this post for the next four months. On March 25, 1865, the regiment fought in the Battle of Fort Stedman, the Confederate Army's final offensive during the Siege of Petersburg. Before dawn on March 25, Confederate troops achieved complete surprise and easily occupied Fort Stedman entering the rear
sally port almost unchallenged. Major Charles T. Richardson, then in command of the 29th, hearing some light gunfire, ordered the 29th to fall in. No general alarm had yet been raised, but Richardson felt certain that an attack was underway. Within minutes, approximately 500 Confederates, a small part of the overall offensive, swept over Battery 11. The 29th held their ground, however, engaging in heated hand-to-hand combat and eventually capturing 300 Confederates—more than twice their own number. The Confederates still occupied Fort Stedman, however, and soon sent another offensive to occupy Battery 11. This time, the 29th was forced to retreat back to Fort Haskell, the nearest defensible position. Among the 29th's casualties in this engagement was Sgt. Calvin F. Harlow who, finding himself surrounded by Confederates, refused to surrender. He and the Confederate officer demanding his surrender shot each other simultaneously. Poet
Walt Whitman, learning of Harlow's story, wrote about him in his book
Specimen Days. After four hours, the Confederate attack lost momentum, and their forces began to pull back into Fort Stedman. An overwhelming Union counterattack eventually recaptured the fort. The 29th took part in the counterattack, re-capturing Battery 11. Color-bearer
Conrad Homan of the 29th was the first to re-enter Battery 11 and was later awarded the Medal of Honor. The regiment lost 10 killed and an unknown number of captured in this engagement. ==Mustering out==
