June 24.—We have been in Winchester for the last two days, at Dr. S’s. General Johnston’s army encamped at “The Lick.” Some Southern regiments encamped near Winchester. The army at Manassas said to be strongly reinforced. Measles prevailing there, and near Winchester, among the troops. There has been a slight skirmish in Hampshire, on New Creek, and another at Vienna, in Fairfax County. We repulsed the enemy at both places. Captain Kemper, of Alexandria, led our men in the latter fight, and is much extolled for his dexterity and bravery.
