The havoc wrought by the Confederate attack of August 26th on the Federal supply depot at Manassas Junction is here graphically preserved. When Jackson arrived at sunset of that day at Bristoe's Station, on the Orange & Alexandria Railroad, he knew that his daring movement would be reported to Pope's forces by the trains that escaped both north and south. To save themselves, the troops that had already marched twenty-five miles had to make still further exertions. Trimble volunteered to move on Manassas Junction; and, under command of Stuart, a small force moved northward through the woods. At midnight it arrived within half a mile of the Junction. The Federal force greeted it with artillery fire, but when the Confederates charged at the sound of the bugle the gunners abandoned the batteries to the assaulters. Some three hundred of the small Federal garrison were captured, with the immense stores that filled the warehouses to overflowing. The next morning Hill's and Taliaferro's divisions arrived to hold the position. The half-starved troops were now in possession of all that was needed to make them an effective force. Jackson was now in position to control the movements of the Federal army under Pope. [Illustration: GUARDING THE "O. & A." NEAR UNION MILLS COPYRIGHT, 1911, REVIEW OF REVIEWS CO.] Jackson's raid around Pope's army on Bristoe and Manassas stations in August, 1862, taught the Federal generals that both railroad and base of supplies must be guarded. Pope's army was out of subsistence and forage, and the single-track railroad was inadequate.

The Confederate leader marched fifty miles in thirty-six hours through Thoroughfare Gap, which Pope had neglected to guard. [Illustration: A MILITARY TRAIN UPSET BY CONFEDERATES COPYRIGHT, 1911, REVIEW OF REVIEWS CO.] This is part of the result of General Pope's too rapid advance to head off Lee's army south of the Rappahannock River. Although overtaking the advance of the Confederates at Cedar Mountain, Pope had arrived too late to close the river passes against them. Meanwhile he had left the Orange & Alexandria Railroad uncovered, and Jackson pushed a large force under General Ewell forward across the Bull Run Mountains. On the night of August 26, 1863, Ewell's forces captured Manassas Junction, while four miles above the Confederate cavalry fell upon an empty railroad train returning from the transfer of Federal troops. The train was destroyed. Here we see how well the work was done. THE TRAIN "STONEWALL" JACKSON AND STUART STOPPED AT BRISTOE [Illustration]
