HEADQUARTERS THIRD U. S. COLORED CAVALRY,
Haynes' Bluff, Miss., April 25, 1864.
CAPTAIN: I have the honor to respectfully report that, pursuant to orders, I moved at 6 a. m. on the morning of the 19th of April with one battalion Tenth Missouri Cavalry, 90 men and 4 officers, Major W. H. Lusk commanding, and the Second Battalion, Third U. S. Colored Cavalry, 138 men and 12 officers, Major J. B. Cook commanding, on the Yazoo City road. Dividing my command to cover both ridge and valley road, I proceeded to within 7 miles of Mechanicsburg; returning to the column encamped at the residence of Mr. Willday, on the valley road.
Moving at daylight on the 20th, and accompanied by the First Kansas Mounted Infantry as far as Mechanicsburg, we moved toward Yazoo City, driving in our front about 50 of the enemy's skirmishers. The advance guard of the Tenth Missouri Cavalry, under Captain Cain, was exceedingly fine and worthy of special mention. About 9 miles beyond Mechanicsburg we captured 2 out of the 4 men posted as a picket, and learned that Mabry's brigade, formerly either Adams' or Starke's, was somewhere in our front
*From monthly return.
