`` Good-bye . '' But they did not offer to shake hands . Each turned his back on the other , and , when Harry stopped in the bushes , he saw only the dim outlines of Washington . At midnight he found a colored man who , for pay , rowed him across the Potomac . At dawn he found his horse peacefully grazing in the meadow , and at the next dawn he was once more within the southern lines . Harry found little change in the Southern army , except that more troops had come up from Richmond . It still rested upon Bull Run .
