O. P. (Orlando Phelps) Cutter

O. P. Cutter, identified in library and book records as Orlando Phelps Cutter, is known for Our Battery; Or, The Journal of Company B, 1st O.V.A., published in Cleveland in 1864. The book is a firsthand account centered on Company B of the 1st Ohio Volunteer Artillery and has been preserved by sources including the Library of Congress, Project Gutenberg, and the Internet Archive.

In the author's note, Cutter explains that the work was written during the "leisures of Camp Life" and was not originally meant for print, but was published after encouragement from his fellow soldiers. That gives the book much of its appeal today: it reads less like a polished memoir and more like a soldier's own running record of service, companionship, and military life during the Civil War.

Reliable biographical details about Cutter himself are limited in the sources I could confirm, so it is safest to remember him chiefly through this one surviving book. Even so, that single volume has made him a useful witness to Union artillery life and an accessible voice for readers interested in personal Civil War narratives.
