Colonel Kershaw and Colonel Cash were filing down the east bank to the left, while Colonels Williams and Bacon occupied some earthworks on the right. These had been erected by former troops, who had encamped there before us. General Beauregard had divided his troops into six brigades, putting regiments of the same State together, as far as possible, Bonham's being First Brigade. Beauregard was determined to make Bull Run his line of defense. This is a slow, sluggish stream, only fordable at certain points, its banks steep and rather rocky with a rough plateau reaching back from either side. The western being the more elevated, gave the enemy the advantage in artillery practice. In fact, the banks on the western side at some points came up to the stream in a bluff—especially so at Blackburn's Ford. In the rear and in the direction of the railroad was the now famous Manassas Plains. The Confederate line extended five miles, from Union Mills Ford to Stone Bridge. At the latter place was General Evans, of South Carolina, with two regiments and four pieces of artillery. On the extreme right, Ewell with his brigade and a battery of twelve-pounders was posted at Union Mills. McLean's Ford was guarded by D.R. Jones' brigade, with two brass six-pounders. Longstreet with two six-pounders, and Bonham with two batteries of artillery and a squadron of cavalry, guarded the fords at Blackburn's and Mitchell's respectively. Early's Brigade acted as reserve on the right. In rear of the other fords was Cooke's Brigade and one battery. The entire force on the roll on July 11th consisted of 27 pieces of light artillery and 534 men; cavalry, 1425; foot artillery, 265; infantry, 16,150—18,401, comprising the grand total of all arms of General Beauregard one week before the first battle. Now it must be understood that this includes the sick, guards, and those on outpost duty. McDowell had 37,300 of mostly seasoned troops.
The morning of the 18th opened bright and sunny. To our rear was all bustle and commotion, and it looked like a vast camp of wagon trains. From the surrounding country all wagons had been called in from the foraging expeditions laden with provisions. Herds of cattle were corralled to secure the troops fresh beef, while the little fires scattered over the vast plains showed that the cooking details were not idle. General Beauregard had his headquarters on the hill in our rear.
At eight o'clock on the 18th, McDowell pushed his leading division forward at Blackburn's Ford, where two old comrades, but now facing each other as foes, General Tyler and General Longstreet, were to measure strength and generalship. The Washington Artillery, under Captain Richardson, of New Orleans, a famous battery throughout the war, which claims the distinction of firing the first gun at Bull Run and the last at Appomattox, was with Longstreet to aid him with their brass six-pounders.
The enemy advanced over the plain and up to the very bluff overlooking the stream, and a very short distance from where Longstreet's force lay, but the Washington Artillery had been raking the field all the while, from an eminence in the rear, while the infantry now began to fire in earnest. The elevated position gave the enemy great advantage, and at one time General Longstreet had to call up his reserves, but the advantageous assault was speedily repulsed as soon as the Southern troops became more calm and better accustomed to the fire and tension of the battlefield. Several assaults were made, one immediately after the other, but each time Southern valor overcame Northern discipline. From our position at Mitchell's Ford, we could hear the fierce, continual roll of the infantry fire, mingled with the deafening thunder of the cannon. Bonham was under a continual shelling from long range, by twenty pounders, some reaching as far in the rear as the wagon yard. After the fourth repulse, and Longstreet had his reserves well in hand, he felt himself strong enough to take the initiative. Plunging through the marshes and lagoons that bordered the stream, the troops crossed over and up the bluff, but when on the heights they met another advance of the enemy, who were soon sent scampering from the field. Then was first heard the famous "Rebel yell." The Confederates finding themselves victorious in this their first engagement, [59] gave vent to their feelings by uttering such a yell as suited each individual best, forming for all time the famous "Rebel Yell." Longstreet withdrew his forces to the east side, but a continual fusilade of artillery was kept up until night. Some of our soldiers visited the battlefield that night and next day, and brought in many trophies and mementoes of the day's fight, such as blankets, oilcloths, canteens, guns, etc.
