Gouverneur K. Warren
He was the author of "A Diary of Battle: The Personal Journals of Colonel Charles S. Wainwright, 1861–1865", published posthumously in 1962. His journals provide insights into the administration of the artillery, as well as its use in battle. Wainwright's observations on the Union commanders with whom he served are pungent. Maj. Gen. Gouverneur K. Warren, under whom he had served in V Corps, and Maj. Gen. Joseph Hooker receive particularly negative reviews.
