mend him to your attention and that of Governor Gamble, for one of the vacant field commissions in his regiment, which he has so nobly earned. I should be unjust did I omit to name Captain [J. A.] Lennon, of the same regiment, who, at the head of his company, held a most exposed post, and had several narrow escapes from sharpshooters concealed in the brush. But the artillery saved the battle. Lieutenant [W.] Waldschmidt's gunnery was superb and his coolness astonishing. The enemy's Parrott gun got his range, and fired with great precision, compelling him to change the position of his pieces constantly.

A courier reached Houston, giving me the information of the engagement at 3 o'clock Monday morning. I at once moved with 500 men to Hartville, supposing the enemy still in force. Arriving within 7 miles at 4 p. m., my reconnoitering parties brought me intelligence that they were retreating in the direction of Houston. Sending back a courier with orders to Lieutenant-Colonel Caldwell, in command, to hold the place until I could re-enforce him, I countermarched in all haste, through mud and rain, and reached Houston that evening, finding all quiet.

Colonel Merrill's force rejoined me Thursday, and I am now once more concentrated.

Hoping that our conduct will meet the approbation of the general commanding, I am, colonel, very respectfully, your obedient servant,

FITZ HENRY WARREN,

Brigadier-General, Commanding.

Chief of Staff, Saint Louis, Mo.
