prevented in both cases.
, one of them, had failed to reach Stuart
, at his crossing of the Potomac
, owing to an enforced change of Stuart
's line of march.
, the other, had been captured.
, therefore, on June 28, still believed that Hooker
's army had not yet crossed the Potomac
, and, to hurry Hooker
up, he issued orders for an advance, the next day, of all his forces upon Harrisburg
But there was still one scout, Harrison
, within the Federal

With good judgment and good fortune he appeared about midnight on the 28th, with the news that Hooker

To forestall this, Lee

, behind Pipe Creek
, on the divide between the waters of the Potomac and Chesapeake Bay
Here he, too, hoped to fight on the
