and ordered Hooker to the north bank of the Potomac, to interpose his army between Lee and Washington. The chronicles of the day record this remarkable prayer, by President Lincoln: "O, Lord, this is your fight; but we, your humble followers and supporters here, can't stand another Fredericksburg or Chancellorsville."
From Williamsport, on the 25th, where Longstreet was crossing the Potomac, Lee wrote to President Davis saying, that if the whole of Hooker's army was concentrated upon him he could accomplish nothing, and would be compelled to return to Virginia; but urged that it would be a great relief to him if even the effigy of an army, under Beauregard, were concentrated at Culpeper.

The same day that Lee, in person, crossed the Potomac, June 25th, Hooker began crossing the same river, a fact of which Lee was still in ignorance, at Chambersburg, on the 27th; as Stuart was that day crossing the Potomac, at the mouth of Seneca creek, not far from Washington, between Hooker's army and that city, and was rapidly riding northward into Pennsylvania, cumbered with the spoils he had captured in the rear of Hooker's army.
