In presenting this history of our Regiment to my fellow-soldiers of the 33d Iowa Infantry, I hope their memories while reading, may be as warm and pleasant as have been mine while writing it. For whatever of omission or error it contains, I have only to say, that the whole was written amidst the very press of editorial and many other duties, and a very great part of it after nine o'clock at night. The work is as well as I could make it under the circumstances.

Through the Howling Wilderness is replete with in-depth coverage on the geography of the region, the Congressional hearings after the Campaign, and the Confederate defenses in the Red River Valley.

Of the 620,000 soldiers who perished during the American Civil War, the overwhelming majority died not from gunshot wounds or saber cuts, but from disease.
