because they wanted beaten so hard the southerners .
General Grant, it was not McClellan because he voted against Lincoln in the election. Lincoln 212 McClellan 12.
President Lincoln did second guess himself for a while. This is because General McClellan had years of extensive industry and military experience. Lincoln, however, would soon find a replacement for the ousted General.
President Lincoln and General McClellan clashed because Lincoln did not agree with McClellan at all on some vital military issues.They weren't on the same page when it came time to the policies on the US Civil War. And they clashed in 1862 because it was during the Civil war and both couldn't handle one another anymore.
Union leaders considered the Peninsula Campaign a failure because General McClellan retreated without taking Richmond. Or, at least place the city under siege. Actually is was not much of a decision to make. Everyone, including McClellan saw it as a failure, however, McClellan blamed it all on President Lincoln for not giving him the troops he requested. In fairness, Lincoln had removed to divisions from McClellan to protect Washington DC. Lincoln was over cautious, there was no immediate threat to Washington DC at that time.
He doubted he would win the election because the democrats nominated General George McClellan who was very popular and people cherished him.
After many delays, General McClellan began his advance from Harper's Ferry on November 2, 1862. According to President Lincoln's plan, McClellan was to place the Army of the Potomac between Lee's army and Richmond. Because of the delay, Lee was able anticipate what McClellan was attempting and took steps to prevent this from happening.
Because his Peninsula campaign had failed, and some of Lincoln's cabinet thought he might even be a Confederate spy.
No one doubts the brilliance of George B. McClellan as being a military genius. Those who do are entitled to their opinions. One Union major general had suggested the best solution of all. Because of McClellan's brilliance and we can assume his "commanding" slowness, the best thing that Lincoln could have done was to retain McClellan as general in chief and appoint a good general to head the Army of the Potomac. This would have relieved him of the stress of the battlefield, and use his fine military mind to create strategies and allow his major generals to carry them out. The Secretary of War, Stanton and US President Lincoln were good politicians and military strategies they themselves would have to admit were not their forte'.
Because Lincoln felt that McClellan lacked the aggressiveness required to successfully defeat the Confederate army. McClellan was very meticulous and patient. He did not chase Confederate General Robert E. Lee after defeating his troops at Antietam. Lincoln got tired of McClellan's patience and decided to replace him with Ambrose Burnside.
The reasons behind Lincoln's dismissal of McClellan were complex. With that said, President Lincoln had few choices. Ambrose Burnside replaced General George B. McClellan after the Battle of Antietam. Prior to his final dismissal in November of 1862, McClellan was stripped of his army in favor of the new army under General John Pope. Most people believed that McClellan's career was over. However, Pope's defeat at the second Battle of Bull Run saw Lincoln restore McClellan as the leader of the Army of the Potomac. Lincoln's cabinet objected to give McClellan command of the Army of the Potomac, but Lincoln correctly reasoned that this army loved McClellan and would fight their best under his command.
Because he had caused so many delays tha some of Lincoln's cabinet were starting to doubt his loyalty to the cause, and after the Battle of Antietam, he failed to pursue and destroy the enemy.
