General McClellan had significant character flaws that I believe serve as a warning signs to anyone in leadership. Ultimately, these cost him dearly: He lost Lincoln’s confidence, his job, and a run for the White House (against Lincoln). Worse, they prolonged the Civil War and cost the lives of tens of thousands of soldiers on both sides of the conflict.
