The War Department decides that Generals Fremont and McClellan outrank General Benjamin Butler
The War Department sought to settle the simmering debate, especially between Major General Benjamin Butler and Major General John C. Fremont, over who held precedence of rank in the Union Army. The Secretary of War had earlier assembled a high ranking board to investigate the matter and they gave their report, namely that all four major generals, George B. McClellan, John C. Fremont, John A. Dix, and Nathaniel Banks had precedence of rank above Butler. (By John Osborne)
