Half a mile below the town we forded the Potomac for the third time, and by the middle of the afternoon were on the outskirts of Sharpsburg, four miles from the river. On the opposite, or east, side of this village are Antietam creek and valley; a mile from the creek and parallel to it was a heavily wooded mountain. It is not my design to attempt a description of the battle which was fought on this ground on the following day, generally conceded to have been the fiercest of the war, but only to mention what came under my observation or was especially associated therewith.
The unusual activity and aggressiveness on the part of General McClellan, as evidenced by the fierce attacks made on our forces in the South Mountain passes for the two preceding days, were explained by his being in possession of General Lee's order to his subordinates. This order, or a copy of it, which contained directions for the movements of the various portions of the Confederate army, including the investment of Harper's Ferry, had been lost or disposed of by some one in Frederick City, and when this place was occupied, on September 13, by the Federals, was delivered to General McClellan. Thus acquainted with the location and movements of each division of the Confederate army, which was scattered over a wide territory and separated by a river and rugged mountains, it seems surprising that with his army of 90,000 men he should not have practically destroyed General Lee's army of 40,000. General Lee, however, was informed early on the morning of the fourteenth that a copy of his order had fallen into the hands of General McClellan.
This was done by a citizen of Frederick City who happened to be present when General McClellan received it and heard him express satisfaction over such a stroke of luck. This citizen at once went to work to inform General Lee, which task he accomplished by passing through the Federal lines during the night and informing General Stuart, who forthwith communicated it to General Lee, who lost no time in moving heaven and earth—the former by prayer, we assume; the latter by his authority over men—to meet the emergency. Results proved how wonderfully he succeeded.
As we moved past the town we saw neither any of our troops nor those of the enemy, and heard no firing. Although there was complete absence of the usual prelude to battle, still the apprehension came over us that something serious in that line was not very remote, either in time or place. The commanders of both armies were conscious of the importance of the impending contest, which perhaps explains the extreme caution they exercised.
After passing through a piece of woodland, we entered a small field and came in distinct view of two blue lines of battle, drawn up one in rear of the other. On these we at once opened fire, and were answered very promptly by a Federal battery in the same quarter. While thus engaged we had a visitor in the person of a young fellow who had just been commissioned a lieutenant, having previously been an orderly at brigade headquarters. Feeling his newly acquired importance, he spurred his horse around among the guns, calling out, "Let 'em have it!" and the like, until, seeing our disgust at his impertinent encouragement, and that we preferred a chance to let him have it, he departed. Our next visitor came in a different guise, and by a hint of another kind was quickly disposed of. He, a man of unusually large size, with sword dangling at his side, came bounding from our right at a full run. A large log a few steps in our rear was his goal as a place of safety, and over it he leaped and was instantly concealed behind it. He had scant time to adjust himself before the log was struck a crashing blow by a solid shot. He reappeared as part of the upheaval; but, regaining his feet, broke for the woods with the speed of a quarterhorse, and a greater confidence in distance than in logs.
It was now dark, and our range had been accurately gotten. After each discharge of our opponent's guns, what appeared to be a harmless spark of fire, immovable as a star, repeatedly deceived us. It was the burning fuse in the head of the shell which, coming straight toward us, seemed stationary until the shell shot by or burst. Four young mules drawing our battery-forge were stampeded by these shells and ran off through the woods, thus affording Pleasants, our blacksmith, entertainment for the rest of the night.
Firing ceased on both sides at about eight o'clock, and we passed through the woods to our left and went into park on the opposite side. Still feeling the comfort of my clean clothes, I enjoyed a quiet night's rest on the top of a caisson, little heeding the gentle rain which fell on my face. Our bivouac was immediately by the "Straw-stacks," which have been so generally referred to as landmarks in this battle, and which were located in the open ground near the forest which extended to the Dunkard church. About seven o'clock next morning, while standing with horses hitched and awaiting orders, no engagement so far having taken place near us, a shell of great size burst with a terrific report. One fragment of it mortally wounded Sam Moore, a driver of my gun, while another piece cut off the forefoot of one of the horses in the team. We soon transferred his harness to another horse which we hitched in his stead and, as we went off at a trot, the crippled horse took his place close by where he was accustomed to work, and kept alongside on three legs until his suffering was relieved by a bullet in the brain.
We had moved, to get out of range of missiles, but the place to which we had just come was not an improvement. While standing with the gun in front turned in file at right angles to those following, a twenty-pound shell swept by the six drivers and their teams in the rear, just grazing them, then striking the ground, ricocheted almost between the forward driver and his saddle as he threw himself forward on the horse's neck. I mention this in contrast with an occurrence later in the day, when one shell killed or wounded all of the six horses in a team, together with their three drivers.
Fighting along the line of four miles had become general—done on our side chiefly by infantry. Jackson's corps occupied the left with a thin line of men, and from it there was already a stream of stragglers. Jackson, while sitting nearby on his horse, watching the battle, was approached by a lad of about thirteen years, who for some time had been one of his orderlies. He began talking in a very animated manner, pointing the while to different parts of the field. Jackson kept his eyes on the ground, but gave close attention to what was said. The boy was Charles Randolph, and soon after this became a cadet at the Virginia Military Institute, and at the battle of New Market was left on the field for dead. Fourteen years after the war, while visiting in a neighboring county, I was introduced to a Reverend Mr. Randolph, and, seeing the resemblance to the soldier-boy, I asked him about Sharpsburg, recalling the incident, and found he was the lad.
The straggling already mentioned continually increased, and seemed to give General Jackson great concern. He endeavored, with the aid of his staff officers who were present and the members of our company, to stop the men and turn them back, but without the least effect; claiming, as they did, the want of ammunition and the usual excuses. The marvel was, how those remaining in line could have withstood the tremendous odds against them; but, from accounts, the enemy suffered the same experience, and in a greater degree. Up to this time, with the exception of a return of our battery to the Dunkard church, where we had fought the evening before, we had done nothing. At about ten o'clock the indications were that if reinforcements could not be promptly had serious consequences would follow. But just after our return from the church to General Jackson's place of observation we saw a long column of troops approaching from the left. This was McLaw's division of Longstreet's corps, which had just reached the field. Their coming was most opportune, and but a short time elapsed before the comparative quiet was interrupted—first by volleys, followed by a continuous roar of battle.
