Many sources believe that General McClellan was too cautious to be a leader. He refused to proceed with anything until everything was fully prepared. He also did not know much about his enemy, which is crucial in any war. He underestimated them greatly. Hope this helps.
<span>McClellan has been criticized by some historians for failure to commit his reserves at the end of the day to destroy the Rebels. He was not quick to act which lead to many failures. They were outnumbered and that was very clear to all but he was confident in himself. Lincoln stood beside him helping him by pressing acts and eventually taking over. </span>
