up the Rappahannock, leaving Trimble's brigade near Freeman's Ford to protect his trains. In the afternoon Longstreet sent General Hood, with his own and Whiting's brigade, under Colonel Law, to relieve Trimble. Hood had just reached the position when he and Trimble were attacked by a considerable force which had crossed at Freeman's Ford. After a short but spirited engagement the enemy was driven precipitately over the river with heavy loss. General Jackson arrived at the Warrenton Springs Ford in the afternoon, and immediately began to cross his troops to the north side, occupying the Springs and the adjacent heights. He was interrupted by a heavy rain, which caused the river to rise so rapidly that the ford soon became impassable for infantry and artillery. Under these circumstances it was deemed advisable to withdraw the troops who had reached the opposite side, and they crossed during the night of the 23rd on a temporary bridge constructed for the purpose. General Stuart, who had been directed to cut the railroad in rear of General Pope's army, crossed the Rappahannock on the morning of the 22nd about 6 miles above the Springs, with parts of Lee's and Robertson's brigades. Passing through Warrenton, he reached Catlett's Station at night, but was prevented from destroying the railroad bridge at that point by the same storm that had arrested Jackson's movements. He captured more than 300 prisoners, including a number of officers. Becoming apprehensive of the effect of the rain upon the streams which separated him from the main body of the army, he retired after firing the enemy's camp, and recrossed the Rappahannock at Warrenton Springs.
On the 23rd General Longstreet directed Colonel Walton, with part of the Washington Artillery and other batteries of his command, to drive back a force of the enemy that had crossed to the south bank of the Rappahannock near the railroad bridge upon the withdrawal of General Jackson on the previous day. Fire was opened about sunrise and continued with great vigor for several hours, the enemy being compelled to withdraw with loss. Some of the batteries of Colonel S. D. Lee's battalion were ordered to aid those of Colonel Walton, and under their united fire the enemy was forced to abandon his position on the north side of the river, burning in his retreat the railroad bridge and the neighboring dwellings. The rise of the river rendering the lower fords impassable, enabled the enemy to concentrate his main body opposite General Jackson, and on the 24th Longstreet was ordered to proceed to his support. Although retarded by the swollen condition of Hazel River and other tributaries of the Rappahannock, he reached Jeffersonton in the afternoon. General Jackson's command lay between that place and the [Warrenton] Springs Ford, and a warm cannonade was progressing between the batteries of General A. P. Hill's division and those of the enemy. The enemy was massed between Warrenton and the Springs and guarded the fords of the Rappahannock as far above as Waterloo. The army of General McClellan had left Westover. Part of [it] had already marched to join General Pope, and it was reported that the rest would soon follow. The captured correspondence of General Pope confirmed this information, and also disclosed the fact that the greater part of the army of General Cox had been withdrawn from the Kanawha Valley for the purpose. Two brigades of D. H. Hill's division, under General Ripley, had already been ordered from Richmond, and the remainder, under General D. H. Hill in person, with the division of General McLaws, two brigades under General Walker, and Hampton's cavalry brigade, were now directed to join this army and were approaching. In pursuance of the plan of operations determined upon,
