Heview of the Gettysburg Campaign. 91
that in availing of it, he might be put completely out of touch with Ewell. Colonel John S. Mosby, in his book, "Stuart's Cav- alry in the Gettysburg Campaign," makes himself largely re- sponsible for Stuart's decision as to choice of routes. He says that after the affair at Middleburg, he penetrated the enemy's lines, and found the different army corps widely separated, no corps being nearer than ten miles to any other : That he re- ported their location to Stuart, and that it would be an easy matter for a column of cavalry to pass between them, and at the same time strike a damaging blow at the wagon trains with which all the roads were filled, and suggested to him to cross the Bull Run Mountains and pass through the middle of Hook- er's army into Maryland. Mbsby was a great favorite with Stuart, and had frequently supplied him with valuable informa- tion. No one knew the country so thoroughly as he did, and his opinions were entitled to great weight.

According to Colonel Mosby, Stuart told him that Lee was anxious to know if Hooker's army was moving to cross the Potomac, which he volunteered to find out. That he did so, and found no signs of movement. That Hooker seemed to be waiting for Lee; that this information was given to Stuart on the morning of the 24th, who was to forward it to Lee. Stuart and Mosby then arranged that the latter should again cross the Bull Run Mountains, and meet Stuart the next day at a designated point, where Mosby would guide the advance as it moved on through Hooker's army to Seneca Ford.
The idea, no matter by whom suggested, of passing through Hooker's army or by his rear, and interposing between him and Washington, doubtless possessed great fascination for Stuart. It suited his daring spirit and love of adventure. The prize held out in the way of spoils had its attractions, for if the cav-
