Supposing the day lost from the tenor of Howard's despatch, lacking perhaps the fullest confidence in that general's ability and experience, and thinking only of how he should save what was left, Meade forthwith posted Hancock off to Gettysburg, with full authority to take command of all the troops he might find there, decide whether Gettysburg should be held or given up, and to promptly report his decision, to the end that proper steps might be taken to counteract this disaster if yet possible. [Sidenote: Slocum and Sickles.] Slocum would not stir from Two Taverns without orders, though it is said the firing was distinctly heard there, and he could have reached Gettysburg in an hour and a half. A second and still more urgent appeal decided that commander, late in the afternoon, to set his troops in motion. It was then too late. Sickles, who might have been at Gettysburg inside of three hours with the greater part of his corps, appears to have lingered in a deplorable state of indecision until between two and three o'clock in the afternoon, before he could make up his mind what to do. It was then too late.[40] By contrast we find Ewell promptly going to Hill's assistance upon a simple request for such coöperation, though Ewell was Hill's senior; and we further find that his doing so proved the turning-point of this very battle. [Illustration: Union Positions, July 1, 3 P.M.] Was there a want of cordiality between the Union commanders? Was it really culpable negligence, or was there only incapacity? While, therefore, one corps certainly, two probably, might easily have got to the field in season to take a decisive part in the battle, but remained inactive, the Confederates were hurrying every available man forward to the point of danger. This was precisely where Reynolds' fall proved supremely disastrous, and where an opportunity to acquire a decisive superiority on the field of battle was most unfortunately thrown away for want of a head.[41] [Sidenote: New Union Line.] The Union line, lengthened out by the arrival of the Eleventh Corps, had now been carried in a quarter circle around Gettysburg, or from the Hagerstown road on the left to near Rock Creek on the right, the Eleventh Corps being deployed across the open fields extending from the Mummasburg to the Harrisburg road, with Barlow's division on the extreme right. When this corps formed front in line of battle, there was a gap of a quarter of a mile left wide open between it and the First Corps. Furthermore, it was drawn up on open ground which, if not actually level, is freely overlooked by all the surrounding heights. That this corps was badly posted was demonstrated after a very brief trial. [Sidenote: Rodes attacks.]
