 After the defeat of Pope at Second Bull Run, President Lincoln reluctantly returned to the man who had mended a broken army before.He realized that McClellan was a strong organizer and a skilled trainer of troops, able to recombine the units of Pope's army with the Army of the Potomac faster than anyone.On September 2, 1862, Lincoln named McClellan to command "the fortifications of Washington, and all the troops for the defense of the capital".
