It would be called the Battle of Helena, Arkansas, and considering the Union Army would experience two of its greatest victories on the same day, this smaller battle of July 4, 1863, gained scarce attention. In an unsuccessful bid to seize the Union fort there, and relieve pressure on Vicksburg, Confederate Lieutenant-General Theophilus Holmes' failed attack, would eventually lead to the fall of Little Rock, Arkansas. One of the Union defenders at Helena, was then Lt Adam Burns Smith, of Company B, 33rd Missouri Volunteers. Arriving in Helena four months prior to the attack, Adam kept a diary of daily life at his new post.
Some day's Adam wrote extensively of his daily activities. Other days, the boredom became overpowering.

Lt Smith is buried in the Memphis National Cemetery -
his memorial is here
As the handwriting is pretty clear, I did not transcribe.
