More about this marker. When revisiting the site of this historical marker on August 1, 2012, I noticed that the metal plaque on the reverse side of this monument is now missing. I would guess that it was stolen by scrappers, seeking valuable metals to sell at the local scrap metal dealers in order to obtain cash.
According to the description information provided by the National Park Service, the monument is, “7'6" x 4'4" x 4'6" high rock-faced monument consisting of rectangular granite block with an inscribed polished front on granite base. The tops of both pieces are beveled. Marks unit's position on Sept. 20, 1863, from 2:00 to 6:00 p.m.”
I used the "Chickamauga Battlefield" map, that I purchased at the Chickamauga and Chattanooga National Military Park, Visitor Center, to determine both the marker number for this monument and the monument's location in relation to the rest of the park's monuments, markers, and tablets. According to the map it provides the, "numerical listing of all monuments, markers, and tablets on the Chickamauga Battlefield (using the Chick-Chatt NMP Monument Numbering System).”
Regarding 115th Illinois Infantry. The 115th Illinois Infantry was part of the forward brigade (Whitaker's Brigade) of Steedman's Division which arrived at the Union position on Snodgrass Hill at the critical moment of the battle. When directed to provide support for the Union right flank, Steedman directed Whitaker's Brigade to rush up to crest of the ridge, arriving just in time to drive off the Confederate forces that were on the verge of flanking the beleaguered 21st OVI, situated on what had been the extreme right flank of the Union line
of battle.
