He also investigated ancient Indian earthworks throughout the state.
With the outbreak of the CIVIL WAR, Whittlesey was appointed assistant quartermaster general by Gov. Dennison. Later, as colonel in the 20th Ohio Volunteer Infantry, he planned and constructed fortifications at Covington, Ky., defending Cincinnati, Ohio. He commanded a brigade at Ft. Donelson and participated in the Battle of Shiloh (1862). Whittlesey resigned his commission in Apr. 1862 because of ill health. After the war, he became active as a historian. In 1867 he published Early History of Cleveland and helped found the WESTERN RESERVE HISTORICAL SOCIETY, serving as its president until 1885. Whittlesey married Mary E. Morgan in 1858.
