Major-General BUTTERFIELD, Headquarters Army of the Potomac:

I can bridge Goose Creek anywhere within one-half mile of its mouth. I was informed this morning by an officer of General Howard's command that a good road could be made from General Howard's headquarters to the mouth of Goose Creek. CHAS. N. TURNBULL, Captain of Engineers.

HEADQUARTERS SECOND CORPS, Thoroughfare Gap,
June 22, 1863-6. 20 [p. m.]

General BUTTERFILED, Chief of Staff:

About 1 p. m. a squadron of my cavalry, sent from Gainesville toward New Baltimore, fell into an ambush 2 miles beyond Buckland Mills; were driven to within 2 miles of Gainesville, with a reported loss of 30 men. The attacking force was about a regiment of cavalry. Our cavalry, however, I have no doubt picket to within a mile of New Baltimore, as a squadron sent on the road from here to New Baltimore had a skirmish with the enemy near the junction of this road and the Warrenton pike, and held its ground.

Major-General.
