Slower than his adversary, and failing to follow up with vigor his advantage already gained, Hooker assumes command in person, and reconnoitres the ground between himself and Fredericksburg. He then orders Meade, with Griffin, followed by Humphreys, and with three batteries, to march along the river road to some commanding point between Mott and Colin Runs; his advance to be masked by throwing out small parties, and his command to be in position by two P.M., while Sykes's division, supported by Hancock's division of the Second Corps, march out the turnpike to a corresponding distance, each force then deploying towards the other, and engaging the enemy supposed to be in that vicinity. A third column, consisting of the Twelfth Corps, he orders to march by the plank road, and to be massed near Tabernacle Church, masked in like manner; to be in position by midday, so that the Eleventh Corps can move up to take position a mile in its rear as reserve, by two P.M. French's division of the Second Corps, and one battery, are ordered to Todd's Tavern, from which detachments are to be thrown out on the various roads. The unemployed troops are massed at Chancellorsville, out of the roads. Pleasonton holds his cavalry brigade there in readiness to move. Hooker announces his headquarters at Tabernacle Church as soon as the movement opens. Immediately after (11.30 A.M., Friday,) Sedgwick is directed to threaten an attack at one P.M., in the direction of Hamilton's Crossing, to ascertain whether the enemy is hugging his defences in full force. A corps is to be used with proper supports, but nothing more than a demonstration to be made. If certain that the enemy is there in force, Sedgwick is to make no attack. Sedgwick did not receive this order until about five P. M., but nevertheless made a display in force of Reynolds's corps, with Newton and Brooks in support. But a countermand was soon received, and the troops withdrawn. As Hooker supposed his enemy to be in line somewhere midway between Chancellorsville and Fredericksburg, the purpose of these orders to Sedgwick is not plain. Meade, Sykes, and Slocum were ordered to attack the enemy when met. Sedgwick could aid such an attack by pushing the force in his front at Hamilton's. But a mere demonstration to find out whether the heights were strongly held could have no effect upon the real advance, nor procure Hooker any timely information. The movement of the three columns out of the Wilderness begins at eleven A.M. It is in accordance with the declared plans of Hooker, and with sound policy. For Chancellorsville is of all places the worst in which to deliver or accept a general engagement, and every mile's advance towards Fredericksburg brings the army into more open ground.
