Colonel Fairfax:
"On reaching the line of troops you were taken off the horse and propped up against a tree. You blew the bloody foam from your mouth and sad, 'Tell General Field to take command, and move forward with the whole force and gain the Brock road,' but hours were lost."
Swinton, a Northern historian:
"It seemed, indeed, that irretrievable disaster was upon us; but in the very torrent and tempest of the attack it suddenly ceased and all was still. What could cause this surcrease of effort at the very height of success was then wholly unknown to us."
Winfield Hancock to Longstreet after the war:
"You rolled me up like a wet blanket, and it was some hours before I could reorganize for battle."
