General Ord had the Sixth, Ninth, Tenth, and Twelfth Regiments of Pennsylvania Reserves, with four guns of Easton's battery, and a company of cavalry. One of the regiments wore bucktails in their caps instead of plumes. The soldiers of that regiment were excellent marksmen. They were from the Alleghany Mountains, and often had the valleys and forests and hillsides rung with the crack of their rifles. They had hunted the deer, the squirrels, and partridges, and could bring down a squirrel from the tallest tree by their unerring aim. General Stuart had the First Kentucky, Sixth South Carolina, Tenth Alabama, Eleventh Virginia, with the First South Carolina Battery, commanded by Captain Cutts, also a company of cavalry. The two forces were nearly equal. General Ord started early in the morning. The ground was frozen, the air was clear, there was a beautiful sunshine, and the men marched cheerily along the road, thinking of the chickens and turkeys which might fall into their hands, and would be very acceptable for Christmas dinners. They reached Difficult Creek at noon where the troops halted, kindled their fires, cooked their coffee, ate their beef and bread, and then pushed on towards Dranesville. An officer of the cavalry came back in haste from the advance, and reported having seen a rebel cavalryman. "Keep a sharp lookout," was the order. The column moved on; but General Ord was prudent and threw out companies of flankers, who threaded their way through the woods, keeping a sharp eye for Rebels, for they had heard that the enemy was near at hand. On reaching Dranesville, General Ord sent a company down the Centreville road to reconnoitre. It was not long before they reported that the woods were full of Rebels. General Ord formed his men on both sides of the Centreville road. He sent the Ninth and Twelfth west of Mr. Thornton's house, into the woods, posted the Bucktails in front of the house, put three of Easton's guns into position on a hill east of it, put the Tenth Regiment and the cavalry in rear of the battery on the Chain Bridge road, sent one cannon down the Chain Bridge road a short distance to open a flank fire, and directed the Sixth Regiment to take position west of the Centreville road, to support the Bucktails, and detached one company of the Tenth to move down the Alexandria road to cover the flanking cannon. [Illustration: BATTLE OF DRANESVILLE. 1 General Ord's line. 2 General Stuart's line. 3 Road to Georgetown. 4 Road to Alexandria. 5 Road to Centreville.] Standing by Thornton's house, and looking south, we see the Rebels on a hill, about half a mile distant. General Stuart plants his six guns on both sides of the road, to fire toward the Bucktails. The Eleventh Virginia and Tenth Alabama are deployed on the right of the road, and the Sixth South Carolina and the First Kentucky are sent to the left. The cavalry is drawn up behind the battery.
