Several affairs occurred during the five days Lee was detained on the right bank. In one of these Gregg's brigade was moved up to support a battery, and subjected to a severe shelling from a high hill on the left bank, losing several men killed and wounded. On August 23d a more serious affair occurred, in which the brigade of General Evans and Boyce's battery were engaged. The enemy had fortified a hill near the railroad bridge at Rappahannock Station, and on the right bank. Evans, supported by several batteries, was ordered to attack. The brigade moved up promptly against the fortified position, under a sharp counter fire, but before they reached charging distance the enemy retired, leaving his intrenching tools and other property, but taking guns and troops securely over the railroad bridge, which he fired and destroyed. Evans ordered Boyce to occupy the steep hill with his battery, and that gallant officer at once moved up but was immediately subjected to the fire of four batteries from commanding heights on the north bank. He was compelled immediately to withdraw, losing 8 killed and 14 wounded, and 7 horses killed. Lieut. William Monro of the battery was severely wounded. The brigade lost in this affair 27 killed and 84 wounded, a total of 111.
Without waiting for the arrival of the reinforcements from Richmond, General Lee began his movement around the right of General Pope on the 25th of August.

Jackson marched early on the 25th, crossed the upper branches of the Rappahannock, and camped at Salem, on the Manassas Gap railroad. On the 26th he turned
