Ayre Hill, where the batteries were stationed, is a very commanding point, and is, perhaps, the highest ground in Fairfax County. The purpose of the enemy was evidently to get the cars with the Federal troops on the straight line of the road before opening their murderous fire. There were three six-pound guns in the battery. The Ohio companies behaved with much credit in their unpleasant position, and General Schenck, particularly, displayed perfect coolness and self-possession. There had been undoubtedly a lack of forethought in neglecting to send scouts in advance, as the country is favorable to such reconnoitering; but when once in the difficulty, both men and officers acted bravely. They kept undisputed possession of the point where they had posted themselves, the enemy not deeming it prudent to follow up the attack, but contented themselves with burning the cars, although, with greatly superior numbers, they might easily have captured the entire Federal force. A loss of eight killed and twelve wounded on the part of the Federalists was the sequel to the sad and disastrous transaction, and when the Sixty-ninth New York advanced to Vienna the next day, no trace could be found of the enemy. The place was deserted, and silence reigned where the little band of men had been so nearly sacrificed. REVIEW AT WASHINGTON. A few days before the army of the Potomac was to make its advance, thirty thousand new troops passed through Washington, and were reviewed by the President and his Cabinet. A stand had been erected in front of the White House, in full view of Jackson’s monument, on which Lincoln, Seward, Chase, and other members of the Cabinet sat while these troops passed them in review. Eloquent speeches were made, and the most unbounded confidence expressed in the soldiers’ ability to win a glorious victory over the enemy whenever they should meet him in the open field. The troops listened with interest, and answered these glowing predictions with enthusiastic shouts, as they passed away from the parade ground and marched in solid columns across the Long Bridge that spans the Potomac, there to share a destiny far different to the promised glory, on the battle field of Manassas. Another imposing ceremony was witnessed in Washington on the afternoon of the review. A flag was to be raised on a staff near the Treasury Department, and this was a kind of work that Lincoln loved to accomplish with his own hands; so he moved with his Cabinet down to the point of operation. A platform had been erected at the foot of the flagstaff, and when the President took his place upon it, thousands and thousands of loyal citizens gathered around to see the glorious bunting hoisted in mid-air.
