While doing some family history research, I've found that the brother of my great great grandfather (my maternal side) was in Company B, of the 18th Regiment. The record shows that Matthew Oller enlisted in early 1861 and served through the battle of Ft. Donelson, where he was wounded and captured. After his exchange, he remained with the 18th through the end of the war. He died of pneumonia in the army hospital Pine Bluff, Arkansas in October 1865.
Does anyone out there have any or know the whereabouts of any photo's of the 18th Illinois? Any help would be appreciated.
