General John F. Reynolds, a true Pennsylvanian, was in command of our entire advance, which consisted of the First and Eleventh Corps, about twenty-two thousand strong. As General Wadsworth was placing his division in position, General Reynolds went forward quite alone to reconnoitre, when he discovered a heavy force of the enemy in a grove not far distant. Dismounting quickly he crouched down by a fence through which he sought to survey the force and its position by means of his field-glass, when a whistling ball from a sharpshooter's musket struck him in the neck. He fell on his face and baptized with his life-blood the soil which had given him birth. His untimely fall, especially at this crisis and almost in sight of his childhood's home, was generally lamented. His lifeless form was borne away to the rear just as the Rebels in heavy force advanced upon not more than one-third their number. General Abner Doubleday had to assume command of our forces under this galling fire, having arrived with a portion of the First Corps, the remainder of which and the Eleventh Corps, not being able to join them until two hours of fearful destruction had gone on. Our feeble advance was compelled to fall quickly back upon Seminary Hill, just west of the village, and were pursued very closely, so much so that one portion of our line, seeing its opportunity, swung around rapidly, enveloping the Rebel advance and capturing General Archer the leader and about eight hundred prisoners. On the arrival of the Eleventh Corps, General O. O. Howard, being the ranking officer present, assumed command, giving his place to General Carl Schurz. Our men, now emboldened by these fresh arrivals of helpers, and having alighted upon a fine commanding position, renewed the fight with spirit and wonderful success. This prosperous tide of things continued until about one o'clock P. M., when their right wing was assailed furiously by fresh troops, which proved to be General Ewell's Corps, which had been marching from York, directed by the thunder of battle.
