USA HISTORY

Detailed explanation-1: -Lincoln’s military commander, General George McClellan, was vehemently against emancipation. Many Republicans who backed policies that forbid black settlement in their states were against granting blacks additional rights.

Detailed explanation-2: -Convinced that McClellan could never defeat Lee, Lincoln notified the general on November 5 of his removal. A few days later, Lincoln named General Ambrose Burnside to be the commander of the Army of the Potomac.

Detailed explanation-3: -In 1862, McClellan’s Peninsula Campaign unraveled after the Seven Days Battles, and he also failed to decisively defeat Robert E. Lee’s Confederate Army at the Battle of Antietam. Frustrated by McClellan’s cautious tactics, Lincoln removed him from command.

Detailed explanation-4: -As a commander, McClellan’s chief contribution to the Union cause was his brilliant ability to organize and train troops. Otherwise, he proved to be a cautious and indecisive leader. He repaid President Lincoln’s patience with him with disrespect.
