I got on him again, when all of a sudden he lifted his head, pricked up his ears, began to champ his bit, gave a little squeal, got a little faster, and finally into a gallop and then a run.

He seemed all at once to have remembered or to have forgotten something, and was now making up for lost time.
With all my pulling and seesawing and strength I could not stop him until he brought up with me at Corinth, Mississippi..
