General George B. McClellan

Lincoln relieved McClellan of his title on March 11, 1862. McClellan was not in Washington DC at this time. He was in the process of organizing the Peninsula campaign.

He appointed General Don Carlos Buell to head the Department of Ohio, and General Henry W. Halleck to head the Department of Missouri. As an aside, at the time, little did both McClellan nor Halleck know that before the year of 1862 was over, Halleck would replace McClellan as general in chief.
General George B. McClellan's departure for his Peninsula campaign gave President Lincoln an opportunity to reorganize the Union's armies.

As general in chief, McClellan would have never approved of the abolitionist General Fremont. Needless to say, McClellan was hugely disappointed with the loss of his most sought after position as general in chief.
