HEADQUARTERS SIXTH NEW YORK CAVALRY,

CAPTAIN: In compliance with orders from Brevet Brigadier-General Devin, I have the honor to report that on the evening of the 19th instant in accordance with instructions received from Brevet Brigadier-General Devin, the Sixth New York Cavalry was formed in columns of platoons north of the bridge on Cedar Creek, for the purpose of charging the enemy. The command charged in column across the bridge, driving the enemy's infantry from the opposite side into the first crest of woods. it this moment several mounted men appeared on the hill on our right, one of whom waved a red flag. Mistaking them for the enemy, the command turtled to the right, where we found General Custer with the First Vermont and Fifth New York Cavalry. The regiment was here formed on the left of General Custer's command, and charged at the same time. The charge was continued through the town of Strasburg. At the outer edge of the town the advance halted, the men having become scattered in securing and carrying off the plunder. The advance mentioned consisted of ten or fifteen men belonging to the First Vermont and Fifth and Sixth New York Cavalry. In charging the bridge we lost one man wounded. In charging the artillery and trains we lost our adjutant (John G. Main) killed and one man severely wounded. The colors of the Forty-fourth Georgia (captured by Chief Bugler Thomas M. Wells[Awarded a Medal of Honor. ]), seven pieces of artillery, one caisson, a number of wagons and ambulances, besides a number of prisoners were brought in by this command' tall of which was turned over to Lieut. W. N. Chamberlin, acting quartermaster.

All of which is respectfully submitted.
