WM. D. WHIPPLE,
HDQRS. FIRST CAV. DIV., DEPT. OF THE CUMBERLAND,
Opposite Campbellton, July 27, 1864 - 9 p. m.
Captain L. M. AYTON,
I arrived opposite Campbellton at 4 p.m. The rebels have the whole river picketed in this vicinity, though not in sufficient force to have prevented my crossing. The pontoon train, however, at the hour I write, is not yet within six miles of me. Captain Kossak has found it impossible to pull it up with his mules. I will take some of my cavalry horses and pull it up. This delay will involve the probable necessity of crossing below here, as the attention of the enemy has, I think, been attracted to this point for some reason, as there have been none of them here recently until last night, when a brigade came down to picket their different ferries. I have endeavored to conceal my force, and think the rebels are not yet seriously alarmed. I expected to have reached Fayetteville to-night, and but for the disability on the part of the pontoon train would have done so. I now think I will be able to cross by daybreak at some point. Nothing has been found on this side of the river except small scouting parties of Texas cavalry. It is twenty-six miles from here to the point from which we moved our camp this morning.
I am, captain, very respectfully, your obedient servant,
E. M. McCOOK,
Brigadier-General, Commanding Division.

Colonel Murray telegraphs that Captain Cummings, Third kentucky Cavalry, routed Jordan's guerrillas yesterday, killing Captain McElroy, wounding Jordan and quite a number of his party. He is still in pursuit. A scouting party has just returned from Stilesborough, having met a party of twenty or twenty-five rebels. They captured horses and equipments, but failed to take any of the party.
