Lincoln wanted men of level heads for important commands. Not infrequently he gave his generals advice.
He appreciated Hooker's bravery, dash and activity, but was fearful of the results of what he denominated "swashing around."
This was one of his telegrams to Hooker:
"And now, beware of rashness; beware of rashness, but, with energy and sleepless vigilance, go forward and give us victories."
