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.
