There was no indecision either at Washington or in the Army of the Potomac. Lincoln’s horse-sense, sometimes tripping, but oftener adequate to deal with unparalleled burdens, homely, terse, and unerring in its expression, was at its best in these days. To Hooker, meditating movements along and across the Rappahannock, he wrote: “I would not take any risk of being entangled upon the river like an ox jumped half over a fence, and liable to be torn by dogs in front and rear without a fair chance to gore one way or kick the other.”[245] And again: “If the head of Lee’s army is at Martinsburg (near the Potomac), and the tail of it on the plank-road between Fredericksburg and Chancellorsville, the animal must be very slim somewhere. Could you not break him?” “Fret him and fret him,” was the President’s injunction to Hooker, regarding the advance of Lee. Well-poised, good-humored, constant, Lincoln gave no counsel to Hooker in these days that was not sound. Indeed, at this time, Hooker needed little admonition. Alert and resourceful, he no sooner detected the movement of Lee than he suggested an advance upon Richmond, which was thus left unguarded. Lee, of course, had contemplated the possibility of such a move, and, with a nod toward Washington, had joked about “swapping queens.” The idea, which Hooker did not press, being disapproved, Hooker, turning toward Lee, proceeded to “fret him and fret him,” his conduct comparing well with his brilliant management at the opening of the campaign of Chancellorsville. The cavalry, greatly improved by him, under Pleasonton, with divisions commanded by Buford, Duffie, and Gregg, was serviceable as never before, matching well the troopers of Stuart at Brandy Station, Aldie, and Middleburg. Screened on his left flank by his cavalry, as, on the other hand, Lee was screened by a similar body on his right, Hooker marched in columns parallel to those of his foe and farther east, yet always interposing between the enemy and Washington. As June drew to its end the Confederate advance was near Harrisburg, but the Federals were not caught napping. Hooker stood at Frederick, in Maryland, his corps stretched on either hand to cover Washington and Baltimore, touching hands one with the other, and all confronting the foe. * * * * *
