YESTERDAY I SENT THE FIFTH MICHIGAN CAVALRY TO OCCUPY SNICKER'S GAP. I RECEIVED A NOTE FROM THE COMMANDING OFFICER OF THE REGIMENT LAST NIGHT, INFORMING ME THAT AFTER A BRISK FIGHT HE HAD TAKEN POSSESSION OF THE GAP, WITH A LOSS OF 2 WOUNDED. WE CAPTURED ABOUT 12 OF THE ENEMY, BELONGING TO JONES'BRIGADE. ALL IS QUIET TO-DAY, WITH THE EXCEPTION OF SOME LITTLE BUSHWHACKING. MOSBY IS REPORTED AT ALDIE. WE DROVE WHITE'S BATTALION OUT OF THIS COUNTRY YESTERDAY. HE CAPTURED AND PAROLED 2 OF MY MEN. THE REBELS WERE COLLECTING ALL THE HORSES IN THE COUNTY, AND WERE UNAWARE OF OUR PRESENCE UNTIL WE CAME UPON THEM. I WILL RELIEVE COLONEL DE FOREST AS SOON AS COLONEL RICHMOND RETURNS FROM FREDERICK, MD. I AM SHOEING AS RAPIDLY AS POSSIBLE, AND HOPE SOON TO BE READY FOR SERVICE.

VERY RESPECTFULLY, YOURS, &C.,
