The Third Ohio Volunteer Infantry served under two separate terms of enlistment — the one for three months, and the other for three years. The regiment was organized April 21, 1861, and on [xvii] April 27th it was mustered into the United States service, with the following field officers: Isaac H. Marrow, Colonel; John Beatty, Lieutenant Colonel, and J. Warren Keifer, Major. The writer's record begins with the day on which his regiment entered Virginia, June 22, 1861, and ends on January 1, 1864. He does not undertake to present a history of the organizations with which he was connected, nor does he attempt to describe the operations of armies. His record consists merely of matters which came under his own observation, and of camp gossip, rumors, trifling incidents, idle speculations, and the numberless items, small and great, which, in one way and another, enter into and affect the life of a soldier. In short, he has sought simply to gather up the scraps which fell in his way, leaving to other and more competent hands the weightier matters of the great civil war. Many errors of opinion and of fact he might now correct, and many items which appear unworthy of a paragraph he might now strike out, but he prefers to leave the record as it was written, when cyclopedias could not be consulted, not time taken for thorough investigation. Who can really know what an army is unless he mingles with the individuals who compose it, and learns how they live, think, talk, and act?
