General George McClellan was a prominent Union general during the American Civil War. Born in 1826, he graduated from the United States Military Academy and quickly rose through the ranks due to his organizational skills and ability to train troops. McClellan is best known for his leadership during the Peninsula Campaign in 1862, where he aimed to capture the Confederate capital of Richmond, Virginia. Despite his talents, McClellan faced criticism for being overly cautious and hesitant in battle. His reluctance to engage decisively led to missed opportunities against Confederate forces, particularly during the Battle of Antietam. Ultimately, he was relieved of command, but his legacy remains a topic of debate among historians.
