General George McClellan

While reading a history of the United States from 1934, I came across an interesting point about Gen McClellan by Gen Robert E. Lee. The author states; "In truth, Lee had the highest regard for McClellan. Some years after the war he expressed the opinion that McClellan was the best commander the Army of the Potomac ever had and that among his opponents he was the ablest. Indeed, any man who could take such heavy toll of Joseph E. Johnston and Robert E. Lee as McClellan inflicted in almost every battle was no ordinary soldier. Furthermore, few commanders have won the heart of a great army as McClellan won that of the Army of the Potomac". (Is the compliment accurate? I don't know)
