Glover's left upon their right rear, steadily driving the enemy's skirmishers before them, until they drove them across the bayou.

Colonel Geiger, of the Eighth Missouri, deserves especial mention for the ability with which he handled his part of the line; and the coolness and courage with which the field officers of both the Eighth and Merrill's Horse held their men steady, and pushed forward under a galling fire, is worthy of praise.

The officers of my staff-Lieutenant [H. A.] Gleim, Second Missouri Artillery, and Lieutenants [D. O.] Crane and [A. S.] Phelps, Merrill's Horse-bore themselves throughout like soldiers; especially at one time while I was changing horses, and happened to be in range of the two gun battery of the enemy while it was shelling Stange's section (the first time under fire for two of them), they brought and carried their messages and orders with as much coolness as veterans of many battles.

This report has been delayed from the fact that the 11th and 12th were occupied in the pursuit of the enemy, and the report of the different regimental commanders could not be made out in time to have made up this report any sooner.

Congratulating the general and his command upon the brilliant finale of our long and tedious march, I have the honor to remain, your obedient servant,

LEWIS MERRILL,

Colonel, Commanding First Brigade.
