The latter was to be procured, according to the orders of the day, "at Gunnell's or any other rank secessionist's in the neighborhood." The band of marauders between Dranesville and the river was not to be neglected.

The First Brigade, commanded by General Reynolds, was ordered to move to Difficult Run, a small stream that crossed the road between Dranesville and Langley, so as to be in supporting distance should Ord need assistance. A touch of humor attaches to McCall's serious caution to Ord that he should bring his troops back to camp before nightfall without fail.

The protection of this wagon train was entrusted to Colonel J. E. B. Stuart, who afterwards immortalized himself as the Prince Rupert of the South. As a guard for the wagons he had under his command four regiments of
