Here is the link to A.J. Lewis' Civil War journal.
The journal may be viewed in its entirety. Adoniram Judson Lewis was a unique individual and made the ultimate sacrifice to defend his country and the ideals that he so fiercely believed in. His journal starts with his enlistment in the Union Army on 11 Dec 1862. He proceeds to explain his reasoning for joining the military as an unmarried 43 year old man. The journal continues until 11 Apr 1864 when he ends what would ultimately be his final entry by opining, "I think we shall get good weather soon. It is a getting time for it." He then dies from "disease" three months and thirteen days later on 24 Jul 1864.
