fortifications at Winchester, stating that he was arranging to construct a raft bridge over the Shenandoah so that his troops and those at Leesburg could quickly co-operate. At that very time Johnston was sending his stores and baggage to the rear, and on the 7th of March, Whiting withdrew toward Fredericksburg, from his camp on the lower Occoquan, and D. H. Hill, from his at Leesburg, by way of Warrenton, toward the Rappahannock; and on the 9th, the center, under Johnston himself, abandoned Centreville and Manassas. By March 11th all the Confederate infantry and artillery from the Blue ridge to Fredericksburg, were aligned on the south bank of the Rappahannock.
