4th.–Moved at 6 A. M.–After a march of twelve miles in direction of Yorktown, (at about 3 P. M.) came upon the enemy’s entrenchments at Young’s Mills. They fired a few shots, wounding one man of 5th Vermont in the shoulder. They then retired, giving us possession. Their barracks here were built of logs with good fire places and chimneys, and were very comfortable–far superior to any which our troops had had during the winter. We encamped for the night in sight of the deserted fortifications.
