In the afternoon the troops halted for a while on the banks of a little stream to enjoy the first fresh, clear water they had so much as seen for many weeks. At the sight the men broke into cheers, and almost with one accord rushed eagerly to the banks of the rivulet. That night the army bivouacked eight miles from the Atchafalaya, and early the next morning, the 17th of May, marched down to the river at Simmesport, where the transports and the gunboats, having arrived two days earlier, lay waiting. Near Moreauville on the 17th the rear-guard of cavalry was sharply attacked by Wharton; at the same time Debray, lying in ambush with two regiments and a battery, opened fire on the flank of the moving column. While this was going on the two other regiments of Debray made a dash on the wagon-train near the crossing of Yellow Bayou, and threw it into some momentary confusion. Neither of these attacks were serious, and all were easily thrown off. The next day, the 18th, A. J. Smith's command was in position near Yellow Bayou to cover the crossing of the Atchafalaya, and he was himself at the landing at Simmesport, in the act of completing his arrangements for crossing, when Taylor suddenly attacked with his whole force. Mower, who commanded in Smith's absence, advanced his lines as soon as he found his skirmishers coming in, and thus brought on one of the sharpest engagements of the campaign. With equal judgment, skill, and daring, Mower finally drove the Confederates off the field in confusion and with heavy loss, and so brought to a brilliant close the part borne by the gallant soldiers of the Army of the Tennessee in their trying service in Louisiana. Mower's loss was 38 killed, 226 wounded, and 3 missing, in all 267. Taylor reports his loss as about 500, including 30 killed, 50 severely wounded, and about 100 prisoners from Polignac's division. The Confederate returns account for 452 killed and wounded.
