were moving around to his rear in the hope of seizing this coveted position. He immediately ordered the section of artillery which had taken its position near the church, to withdraw, and, with the other guns of the battery, to take position on the Drane Hill, near the junction of the two roads.
This was done with commendable expedition, the guns went at a sweeping gallop to the top of the hill and took a new position with muzzles pointing south. In this direction the advance of the Confederates was driving in the Federal skirmish line. The Centreville Road enters the Alexandria pike a short distance from the junction of that road with the Washington pike. The Confederate advance was along this Centreville Road, and Easton's Battery arrived in the nick of time to cover this important approach.

The two batteries thus engaged marked the centres of their respective lines. The 10th Pennsylvania was placed in support of Easton's Battery, and rendered effective aid in protecting the Federal left. The other four regiments were placed in advan-
