another high-ranking officer into a jumbled Union command. The Washington defenses played host to a number of generals ejected from major theaters of the war or incapacitated for field command by wounds or disease. Maj. Gen. Alexander M. McCook, who had been relieved of command after the 1863 Battle of Chickamauga, was placed in command of the Defenses of the Potomac River & Washington, superseding Christopher Columbus Augur, who commanded the Department of Washington. Augur also commanded the XXII Corps, whose troops manned the capital's defensive works. Maj. Gen. Henry W. Halleck called upon Maj. Gen. Quincy A.

McCook tried to sort out the problem of too many high-ranking generals in the face of Early's advance. He was unable to rid himself of the generals, and their attempts to gain leverage over one another, but a somewhat-workable command structure was established.

Wright and the VI Corps were initially to be held in reserve but McCook immediately decided against it and stated that he felt veteran troops needed to take the front lines against Early's troops. As it was, Hardin's troops engaged in some light skirmishing, but as McCook intended, it was to be Wright's veterans who bore the brunt of the fighting. Opposing forces Union Confederate Battle At about the time Wright's command was arriving in Washington, Early's corps began to arrive at the breastworks of Fort Stevens, yet Early delayed the attack because he was still unsure of the federal strength defending the fort, much of his army was still in transit to the front, and the troops he had were exhausted due to the excessive heat and the fact that they had been on the march since June 13. Additionally, many of the Confederate troops had looted the home of Montgomery Blair, the son
