wrote to Ewell, who, with two of his divisions, was about Hagers- town, Md., Early not having then crossed the river. General Lee says: "I very much regret that you have not the benefit of your whole corps, for with that north of the Potomac you would accom- plish as much unmolested as the whole army could perform with General Hooker in its front. If your advance
causes Hooker to cross the Potomac, or separate his army in any way, Longstreet can follow you." So on June igth it was uncertain whether Longstreet would cross the river or not. On the 22d Hill arrived near Charlestown. Ewell was then ordered to enter Penn- sylvania with his whole corps; Jenkins' Cavalry was with him. That day (22d) in a letter to Ewell, General Lee says: " If you are ready to move you can do so. I think your best course will be toward the Susquehanna, taking the routes by Emmettsburg, Chambersburg. and McConnelsburg. It will depend upon the quantity of supplies obtained in that country whether the rest of the army can follow. If Harrisburg comes within your means, capture it." So on the morning of June 22d it had not been settled that Longstreet and Hill should follow Ewell.
Later in the day (3:30 P. M.) he again writes Ewell: " I also di- rected General Stuart, should the enemy have so far retired from his front as to permit of the departure of a portion of the cavalry, to march with three brigades across the Potomac, and place himself on your right, and in communication with you, &c. I also directed Imboden, if opportunity offered, to cross the Potomac, and perform the same offices on your left." Ewell marched with two divisions down the Cumberland Valley to Chambersburg: thence to Carlisle, where he halted. Early was detached and sent east through the Cashtown pass in the South mountain, to York.
WHAT THE LETTERS SHOW.
These letters of General Lee's show that Stuart could not have been ordered to march on Longstreet' s flank, because (i) Ewell was then in Pennsylvania and Longstreet in Virginia, and (2) Longstreet and Hill had received no orders to march. The next day General Lee wrote to Mr. Davis: "Reports of movements of the enemy east of the Blue Ridge cause me to believe that he is preparing to cross the Potomac. A pontoon bridge is said to be laid at Harper's Ferry; his army corps, that he has advanced to Leesburg and the foot of the mountains, appear to be withdrawing. Their attempt to penetrate the mountains has been successfully repelled by General
