On the north side of the turnpike a road leads off to the right, called the old Hagerstown road, which winds its course through a valley between a spur and the mountain, and courses back to the turnpike along the top. A more rugged route than this opens a way to the mountain-top by a route nearer the pike.

General Pleasonton, not advised of the lost despatch, did not push for a careful reconnoissance on the 13th. At the same time, General Stuart, forced back into the mountains, finding his cavalry unserviceable, advised General D. H. Hill of severe pressure, called for a brigade of infantry, ordered Hampton’s cavalry down to Crampton’s Pass to assist Robertson’s brigade, Colonel Munford commanding, leaving the Jeff Davis Legion, under Colonel Martin, Colonel Rosser with another cavalry detachment, and Stuart’s horse artillery to occupy the passes by the old Sharpsburg road. Colquitt’s brigade of infantry reported to him under his call. After posting it near the east base of the mountain to hold the pass, he rode to join his other cavalry detachments down at Crampton’s Pass. He only knew of two brigades of infantry pressing him back, and so reported. His cavalry, ordered around the Union right under General Fitzhugh Lee, for information of the force in his front, had failed to make report. General Hill ordered two brigades, Garland’s and Colquitt’s, into the pass to report to Stuart, and drew his other three near the foot of the mountain. Garland’s brigade filed to the right after ascending the mountain, and halted near the turnpike. Colquitt’s brigade took its position across the turnpike and down towards the base of the mountain, Lane’s batteries at the summit.

It seems that up to the night of the 13th most of the Confederates were looking with confidence to the surrender at Harper’s Ferry on the 13th, to be promptly followed by a move farther west, not thinking it possible that a great struggle at and along the range of South Mountain was impending; that even on the 14th our cavalry leader thought to continue his retrograde that day. General Hill’s attention was given more to his instructions to prevent the escape of fugitives from Harper’s Ferry than to trouble along his front, as the instructions covered more especially that duty, while information from the cavalry gave no indication of serious trouble from the front.

A little after dark of the 13th, General Lee received, through a scout, information of the advance of the Union forces to the foot of South Mountain in solid ranks. Later information confirmed this report, giving the estimated strength at ninety thousand. General Lee still held to the thought that he had ample time. He sent for me, and I found him over his map. He told of the reports, and asked my views. I thought it too late to march on the 14th and properly man the pass at Turner’s, and expressed preference for concentrating D. H. Hill’s and my own force behind the Antietam at Sharpsburg, where we could get together in season to make a strong defensive fight, and at the same time check McClellan’s march towards Harper’s Ferry, in case he thought to relieve the beleaguered garrison by that route, forcing him to first remove the obstacle on his flank. He preferred to make the stand at Turner’s Pass, and ordered the troops to march next morning, ordering a brigade left at Hagerstown to guard the trains. No warning was sent McLaws to prepare to defend his rear, either by the commanding general or by the chief of cavalry. The hallucination that McClellan was not capable of serious work seemed to pervade our army, even to this moment of dreadful threatening.

After retiring to my couch, reflecting upon affairs, my mind was so disturbed that I could not rest. As I studied, the perils seemed to grow, till at last I made a light and wrote to tell General Lee of my troubled thoughts, and appealed again for immediate concentration at Sharpsburg. To this no answer came, but it relieved my mind and gave me some rest.

At daylight in the morning the column marched (eight brigades with the artillery), leaving Toombs’s brigade. A regiment of G. T. Anderson’s that had been on guard all night was not relieved in time to join the march, and remained with Toombs. The day was hot and the roads dry and beaten into impalpable powder, that rose in clouds of dust from under our feet as we marched.

Before sunrise of the 14th, General Hill rode to the top of the mountain to view the front to which his brigade had been called the day before. As he rode he received a message from General Stuart, informing him that he had sent his main cavalry force to Crampton’s Pass, and was then en route to join it. He found Garland’s brigade at the summit, near the Mountain House, on the right of the road, and Colquitt’s well advanced down the east side. He withdrew the latter to the summit, and posted two regiments on the north side of the pike behind stone walls, the others on the south side under cover of a woodland. Upon learning of the approaches to his position, he ordered the brigade under G. B. Anderson and one of Ripley’s regiments up, leaving Rodes’s brigade and the balance of Ripley’s to watch for refugees from Harper’s Ferry.

While he was withdrawing and posting Colquitt’s brigade, General Pleasonton was marching by the road three-fourths of a mile south, feeling his way towards Fox’s Gap, with the brigade of infantry under Colonel Scammon. Co-operating with this advance, Pleasonton used his cavalry along the turnpike. His batteries were put in action near the foot of the mountain, except one section of McMullen’s under Lieutenant Crome, which advanced with the infantry. The battle was thus opened by General Pleasonton and General Cox without orders, and without information of the lost despatch. The latter had the foresight to support this move with his brigade under Colonel Crook. Batteries of twenty-pound Parrott guns were posted near the foot of the mountain in fine position to open upon the Confederates at the summit.

After posting Colquitt’s brigade, General Hill rode off to his right to examine the approach to Fox’s Gap, near the point held by Rosser’s cavalry and horse artillery. As he passed near the gap he heard noise of troops working their way towards him, and soon artillery opened fire across the gap over his head. He hurried back and sent Garland’s brigade, with Bondurant’s battery, to meet the approaching enemy. Garland made connection with Rosser’s detachment and engaged in severe skirmish, arresting the progress of Scammon’s brigade till the coming of Crook’s, when Cox gave new force to his fight, and after a severe contest, in which Garland fell, the division advanced in a gallant charge, which broke the ranks of the brigade, discomfited by the loss of its gallant leader, part of it breaking in confusion down the mountain, the left withdrawing towards the turnpike. G. B. Anderson’s brigade was in time to check this success and hold for reinforcements. Ripley’s brigade, called up later, came, but passed to the right and beyond the fight. General Hill had posted two batteries on the summit north of the turnpike, which had a destructive cross fire on Cox as he made his fight, and part of Colquitt’s right regiments were put in, in aid of G. B. Anderson’s men. About two P.M., General Cox was reinforced by the division under General Wilcox, and a little after three o’clock by Sturgis’s division, the corps commander, General Reno, taking command with his last division under Rodman.

As Sturgis’s division came into the fight, the head of my column reached the top of the pass, where the brigades of G. T. Anderson and Drayton, under General D. R. Jones, filed to the right to meet the battle, and soon after General Hood with two brigades. The last reinforcement braced the Confederate fight to a successful stand, and held it till after night in hot contest, in which many brave soldiers and valuable officers were lost on both sides.
