SOME knowledge of the slaughter of Gettysburg may be gained by this picture of Trostle's house and barn at which was stationed a Union battery of light artillery. This view shows where the guns stood. Sixty-five of the eighty-eight artillery horses were left dead on the field. About this time, on the last day of the greatest battle of the war, Pickett made his fierce charge, which is one of the mightiest in history. It was witnessed by the two great armies in the middle of the afternoon of a summer day--a most spectacular tragedy of magnificent courage. It has been said that Gettysburg was the common soldier's battle and that its great results were due, not so much to military strategy as to the intelligent courage and the magnificent heroism of the brave soldiers.

A photograph is here shown of the dead soldiers lying on the battlefield. To silence Hazlett's Battery, which was posted on the summit of Little Round Top, the Confederates pushed their sharpshooters among the rocks in the mountain. A few hours before these photographs were taken one of these sharpshooters mortally wounded General Weed, who was directing the movement of his troops from the summit. Lieutenant Hazlett, who was an old schoolmate of the fallen general, was commanding the battery and hastened to take the dying words of his friend and comrade, when he, too, fell dead, pierced by a bullet from the dread sharpshooters. Like a flash the guns of the battery were turned on the "Devil's Den" from which came the fatal shots as this picture attests.
