was ordered to retrace his steps before daylight by the Back road,
which is parallel to and about three miles from the Valley pike, and
attack the enemy at Tom's Brook crossing, while Merritt's
instructions were to assail him on the Valley pike in concert with
Custer. About 7 in the morning, Custer's division encountered Rosser
himself with three brigades, and while the stirring sounds of the
resulting artillery duel were reverberating through the valley
Merritt moved briskly to the front and fell upon Generals Lomax and
Johnson on the Valley pike. Merritt, by extending his right, quickly
established connection with Custer, and the two divisions moved
forward together under Torbert's direction, with a determination to
inflict on the enemy the sharp and summary punishment his rashness
had invited.

The engagement soon became general across the valley, both sides
fighting mainly mounted. For about two hours the contending lines
struggled with each other along Tom's Brook, the charges and counter
charges at many points being plainly visible from the summit of Round
Top, where I had my headquarters for the time.

The open country permitting a sabre fight, both sides seemed bent on
using that arm. In the centre the Confederates maintained their
position with much stubbornness, and for a time seemed to have
recovered their former spirit, but at last they began to give way on
both flanks, and as these receded, Merritt and Custer went at the
wavering ranks in a charge along the whole front. The result was a
general smash-up of the entire Confederate line, the retreat quickly
degenerating into a rout the like of which was never before seen.
For twenty-six miles this wild stampede kept up, with our troopers
close at the enemy's heels; and the ludicrous incidents of the chase
never ceased to be amusing topics around the camp-fires of Merritt
and Custer. In the fight and pursuit Torbert took eleven pieces of
artillery, with their caissons, all the wagons and ambulances the
enemy had on the ground, and three hundred prisoners. Some of
Rosser's troopers fled to the mountains by way of Columbia Furnace,
and some up the Valley pike and into the Massamitten Range,
apparently not discovering that the chase had been discontinued till
south of Mount Jackson they rallied on Early's infantry.

After this catastrophe, Early reported to General Lee that his
cavalry was so badly demoralized that it should be dismounted; a
