I chose to examine Captain Robert H. Sturgess 8th IL. Infantry battle report on his accounts of his regiments movement from camp in Pittsburgh into the Battle of Shiloh. According to Sturgess report, his unit were ordered to take position at 7:33 am on a ridge perpendicular to the camp line of the second brigade. During the day they were left of the 18th IL regiment. The captain of the regiments was shot and forced Sturgess and his men to fall back to regroup. Sturgess in his report describes the terrain as an open field between his regiment and the confederate troops. He also describes his troops advancing forward slowly and on April 7th the regiment were able to hold their position until the day was won. The map that gave me the best idea of the 8th IL infantry was the map showing positions during the Battle of Shiloh, Tenn from Sneden, Robert Knox, 1832-1918. This map depicted the movement because it showed where the regiment was before the battle began and showed the movement by placing arrows on the map. It also aligns with Sturgess battle report that I read.Additional sources I would consult in order to fill the missing gaps on the maps to the report would be to examine the other regiments report (18th regiment of Illinois) to see what they saw Sturgess men do during the battle. This primary source was important for me to see as I read through the actual report. The animated map was very useful for me to get an idea of how the whole picture looked. This meaning, I was able to see all the regiments and how they moved as the battle progressed during the two days. Although the first hand account of the battle report by Sturgess gave a lot of accurate information, another good source to look at would be the confederate sides report on this area of the battle to see their perspective of the movement of the Union soldiers. This may be more difficult since they may not know which regiment was which but could confirm or add to the 8th Illinois INfantry account of the battle.The biggest challenge historians face when attempting to use primary written accounts about battles is the details that may be left out. This could be a bias of information by a commander by making himself look better when there is victory or loss, depending on the battle. The written account could have some details left out or skewed to create a more “perfect” story for that person. Not all written accounts are wrong or lack detail however historians do need to cipher through the information to get the accurate story.
