On the 28th September, 1863, at night, Mouton's, Speights' and Gen. Green's brigades, and Waller's and Rountree's cavalry, and Semmes' battery, crossed the Atchafalaya in two small flats, and bivouacked on the east bank, the rain pouring in all the time.

At 7 A. M., on the 29th, (still raining,) Mouton's and Speights' brigades, under Col. Gray, marched in single file through the muddy swamp, along a blind path, and reached the enemy's rear at 11 1/2 A. M., at a point five miles west of Morganza, on the Mississippi. Mouton's brigade was held in reserve, about a mile and a half from the enemy's position, to meet any force that might be sent from the fortified camp at Morganza. Speight's brigade, under Lieut. Col. Harrison, was sent forward to attack the enemy's infantry camp, at Mrs. Sterling's plantation, on Bayou Fordoche. Gen. Green, in command of all the forces, marched, with his brigade and Semmes' battery, by the main Morganza road, to attack the enemy's advanced cavalry camp at Fordoche bridge, one and a half miles distant from and nearer to Morgan's Ferry than the infantry camp. Stone's regiment and the Pelican battery were left on the west bank, below Morgan's Ferry, to protect the recrossing of the troops in ease of repulse.

The Federal infantry force, the 19th Iowa and the 26th Indiana regiments, and one section of a battery of light artillery, (precise strength not known,) was strongly posted at Mrs. Sterling's sugar house and negro quarters, with a high levee in front.

Speights' brigade was composed of Speight's regiment, Maj. Daniel, Hawpe's regiment, Maj. Malone, and Spaights' battalion, Lieut. Col. A. W. Spaight, Texas Volunteers, and Clark's battalion, Louisiana Volunteers, Lieut. Col. Clark. The regiments were posted in line of battle, in the order named, from right to left, about four hundred yards from the sugar house. We received the first fire of the enemy from the sugar house before our line was entirely formed. We responded with emphasis, but the high sugar cane rendering our shot ineffective, the word "forward" was passed down the line.

A new line of battle was then formed on the edge of an open field, about two hundred yards from the enemy's position, and we now had the Yankees in full view. The rattle of small arms and the shriek of the Minnie balls, were continuous and terrific. We were fighting in the open field, whilst the enemy fought under cover of the sugar house and negro cabins. Our men began to fall thick and fast. It became evident that a charge must be made, and a charge was made. Then arose from earth to sky the Texas yell, and "up and at them," was the word. The Texas brigade, careering through that field of death, looked, as I suppose would look, a thousand furies turned loose from Pandemonium.

In the transit, our loss was severe. Spaights' battalion was the first to reach the sugar house, but was immediately joined, in chivalrons emulation, by portions of Clark's, Hawpe's and Speights' regiments. The Yankees fought well, but were forced to retreat towards and behind the negro houses, closely followed by our men, yelling still, like--like--Texans. In the negro quarters, a hand to hand confliet commenced. The Yankees fought from house to house, giving back towards the levee, whilst their two field pieces, posted in gaps of the levee, let loose their destructive missiles, sweeping the streets of the negro quarters. At length the yard was ours, but it was a costly purchase, for the Yankees, now driven bohind the levee, and not more than sixty yards distant, poured a deadly fire upon our men. A flank movement was attempted in order to turn their position, which could not be overcome by the front without tremendous sacrifice. Our men were jaded by the wet bivouac and long march, and had now fought more than an hour like heroes. An attack being threatened from Morganza, Monton's brigade was still held in reserve, and did not come up. Gen. Green, detained longer than was anticipated in routing the cavalry camp, which was, however, effectually routed, had not brought up his old glorious brigade. For a moment, the battle wavered, but only for a moment. The yell of Green's men (Waller's and Rountree's cavalry) was heard in the distance on the left; our men answered back with a cheer, rushed again upon the works, and the Yankees gave way. At this instant, up came Waller's and Rountree's cavalry, by the road from the left, and the enemy scattered like sheep.

The victory was won, but dearly won. Our loss, twenty-six killed, and eighty-one wounded.

Spaight's battalion, which suffered most in numbers, lost in killed and wounded one-seventh of the men brought into the engagement. Speight's regiment suffered severely, and was next in proportion.

Major Boone, commanding Waller's battalion, was dan gerously wounded; and Lieut. Spivey, of Rountree's, was killed by the retreating foe.

The fruits of the victory were four hundred and seventy-five prisoners; among them two Lieutenant Colonels and thirty-four other officers, two splendid six pounder Parrot guns, a large quantity of medical stores, and a considerable number of Enfield rifles. The two regiments thus cut up and destroyed were veteran troops, who had borne a part in all the battles on the Mississippi.

Major Boone, since the battle, has been compelled to have his right arm amputated, having had two fingers of his left hand shot off in the engagement.
