Affairs in Virginia.
WASHINGTON, May 19. — A dispatch from the headquarters of the Army of the Potomac, dated 6 o'clock Wednesday evening, says the attack on the enemy's right was to have been made at an early hour this morning, but on examining the ground in that vicinity it was found to be unfavorable for handling the army; so the plan was changed, and at 5 o'clock this morning Gen. —— , supported by Hancock on the right and Burnside on his left, advanced against the enemy's works. The rifle pits in front were those which had been abandoned by us, but were filled with rebel sharpshooters, who were soon dislodged and driven through the second line and behind a third and impenetrable abattis, which was of a most formidable character. On examination he deemed it best not to attempt charging through this barrier, and the troops fell back in good order, although exposed to a galling fire of shells and canister from both flanks. Our loss is considerable, being about 800 killed and wounded. Burnside's corps was partly engaged, and of the rest of the above number about one-fourth.
An attack was made on our left in the afternoon where Warren was posted, but our batteries soon drove the enemy back and silenced their guns. All quiet at 6 o'clock P. M.
LATER. — May 18, 6 A. M. — I have just received intelligence that Gueria Station, on the Fredericksburg & Va. R. R., was entered last night by our scouts. They captured the telegraph operators and apparatus. The station and a large quantity of supplies were destroyed.
