GENERAL ORDERS No. 18.
HEADQUARTERS DISTRICT OF ARKANSAS,
Washington, January 25, 1865.
The major-general commanding takes pleasure in announcing to the army that Colonel Brooks, commanding Brooks' brigade, composed of Brooks men proper, Newton's regiment, and Stirman's battalion, after a long and difficult march to the Arkansas River, attacked a heavier force of the enemy near Dardanelle, drove him into his works, killing 8, wounding 19, and capturing 2; loss on our side, 1 killed and 15 wounded. Colonel Brooks, hearing of the approach of steamers from above, by a forced march, with 400 men, reached the proper point at sunrise on the 16th instant. Having placed a piece of artillery and his men in ambush, at 1 o'clock on the 17th, he permitted the leading boat to come well in range, when he opened upon her with his infantry and this piece. She was raked from stem to stern and soon surrendered. She proved to be the New Chippewa. The prisoners consist of 1 officer and 29 men of the Fiftieth Indiana and 40 negroes; also the captain, crew, and a large number of refugee families from Fort Smith. After removing everything valuable the boat was fired. The steamer Annie Jacobs next hove in sight. She was immediately attacked, and the fire was returned by the troops on board. She attempted to destroy our artillerists; our artillery, however, soon disabled her, and she grounded upon an island. Here many men [were] drowned in attempting to make their escape to the opposite bank. During the engagement with the Jacobs the Lotus came down. The troops on board were driven into the water and she to the north bank of the river, where most of them escaped, the iron axle of one piece of artillery having broken. Finding the boats too distant for an effective fire of musketry, Colonel Brooks returned to his camps, taking with him 82 prisoners and the refugee families captured. Federal casualties, 27 killed and wounded, besides those who were drowned; our own loss, 1 killed and 15 wounded. A large quantity of the enemy's stores were destroyed. Colonels Newton and Stirman and Lieutenant Lockhart are spoken of in high terms by Colonel Brooks in his report of their operations. Information has also been received from Maj. Gen. M. M. Parsons that Captain Webb, who was ordered to destroy the enemy's mills at Pine Bluff and to rid the country of graybacks, has succeeded--capturing one company, thirty-seven strong, a number of horses, arms, &c.
The commanding general takes great pleasure in returning his thanks to both officers and men of the several commands for their gallant conduct on this occasion.

By command of Maj. Gen. J. B. Magruder:
EDMUND P. TURNER,
Assistant Adjutant-General.
