At 5 o'clock things changed, as nearly all of the Union artillery was engaged. The bombardment lasted two hours. It was a continuous roar that shook the earth under the feet of the Union soldiers.
After the cannonading ended, there was a large work detail made from every regiment. The detail was sent to work on the artillery fort they had worked on the previous nights.
William Fleming reported the Confederate army was much more aggressive in their efforts to stop the work of the detail.
but we had only got to work when the rebels sent a few shells among us in order to drive us away but they failed we would watch the shells and dodge them but there was some unfortunate and came in collion with there shells and one man got killed and two others wounded and we were relieved at one oclock by another detail
