Gen. Warren, whose whole testimony and report are the clearest and most useful of all the evidence obtainable from any single source, on this campaign, suggested to Couch, who was supporting Sykes on Friday, when the latter was attacked by Jackson, to delay carrying out Hooker's orders to retire, while he (Warren) galloped back to headquarters to explain the importance of holding the position, which was formidable and had great tactical advantages. Hooker yielded; but, before Warren could get back to the front, the previous orders had been obeyed, and the position lost. He says: "I never should have stopped at Chancellorsville. I should have advanced and fought the enemy, instead of waiting for him to attack me. The character of the country was the great reason for advancing." And it is thought that every one engaged in this campaign with the Army of the Potomac will remember the feeling of confusion and uncertainty engendered by the withdrawal from Jackson's front on this unlucky day. A council of general officers was held at Chancellorsville on Friday evening, in which many were still strongly in favor of making the advance again. Warren says: "I was in favor of advancing, and urged it with more zeal than convincing argument." But Hooker held to his own opinion. He could not appreciate the weakness of assuming the defensive in the midst of the elan of a successful advance. It is not difficult to state what Hooker should have done. He had a definite plan, which was to uncover and use Banks's Ford. He should have gone on in the execution of this plan until arrested by superior force, or until something occurred to show that his plan was inexpedient. To retire from an enemy whom you have gone out to attack, and whom you have already placed at a disadvantage, before striking a blow, is weak generalship indeed. Hooker had arrived at Chancellorsville at noon Thursday. Lee was still in Fredericksburg. The troops were able to march many miles farther without undue taxing. They should have been pushed out that afternoon to the open ground and to Banks's Ford. To fail in this, was the first great error of the campaign. There had not been a moment's delay allowed from the time the troops reached the river until they were massed at Chancellorsville, and the proposed movement nearly completed. One continued pressure, never let up, had constantly been exerted by the headquarters of the army. The troops had been kept in constant movement towards Banks's Ford. Hooker had all but reached his goal. Suddenly occurred a useless, unexplained pause of twenty-four hours. And it was during this unlucky gap of time that Lee occupied the ground which Hooker's cavalry could have seized, and which should have been held at all hazards.
