I was hurried off to Centerville, a distance of seven miles, for a fresh supply of brandy, lint, etc. When I returned, the field was literally strewn with wounded, dead and dying. Mrs. B. was nowhere to be found. Had she been killed or wounded? A few moments of torturing suspense and then I saw her coming toward me, running her horse with all possible speed, with about fifty canteens hanging from the pommel of her saddle. To all my inquiries there was but one answer: "Don't stay to care for the wounded now; the troops are famishing with thirst and are beginning to fall back." Mr. B. then rode up with the same order, and we three started for a spring a mile distant, having gathered up the empty canteens which lay strewn on the field. This was the nearest spring; the enemy knew it, and consequently had posted sharpshooters within rifle range to prevent the troops being supplied with water. Notwithstanding this, we filled our canteens, while the Minnie balls fell thick and fast around us, and returned in safety to distribute the fruits of our labor among the exhausted men. We spent three hours in this manner, while the tide of battle rolled on more fiercely than before, until the enemy made a desperate charge on our troops driving them back and taking full possession of the spring. Chaplain B.'s horse was shot through the neck and bled to death in a few moments. Then Mrs. B. and I dismounted and went to work again among the wounded. Not long afterwards Col. Cameron, brother of the Secretary of War, came dashing along the line, shouting, "Come on boys, the rebels are in full retreat." The words had scarcely been uttered when he fell, pierced to the heart by a bullet. Surgeon P. was on the ground in an instant, but nothing could be done for him; his wound was mortal, and he soon ceased to breathe. There was no time to carry off the dead; we folded his arms across his breast, closed his eyes, and left him in the cold embrace of death. Still the battle continues without cessation; the grape and canister fill the air as they go screaming on their fearful errand; the sight of that field is perfectly appalling; men tossing their arms wildly calling for help; there they lie bleeding, torn and mangled; legs, arms and bodies are crushed and broken as if smitten by thunder-bolts; the ground is crimson with blood; it is terrible to witness. Burnside's brigade is being mown down like grass by the rebel batteries; the men are not able to stand that terrible storm of shot and shell; they begin to waver and fall back slowly, but just at the right moment Capt. Sykes comes up to their relief with his command of regulars. They sweep up the hill where Burnside's exhausted, shattered brigade still lingers, and are greeted with a shout of joy, such as none but soldiers, who are almost overpowered by a fierce enemy, and are reinforced by their brave comrades, can give.
