The skirmish near Cox's Mill.
Mr. James Phillips, who was alleged to have been killed in the cavalry fight of Sunday afternoon, near Cox's Mill, in Prince George county, is now known to be in the enemy's hands as a prisoner. His capture resulted from the disabling of his horse in the skirmish. After being reinforced the Yankees advanced as far as the encampment of the 10th Virginia regiment of cavalry, at Sycamore Church, and burned all the tents that were remaining but all the stores had been removed. The Federals stated at Garysville that they had two men severely wounded in the fight, but none killed. They threatened to return in a day or two, but up to noon on Monday they had failed to make good their threat. The Petersburg Express says that the battery put down to destroy the gunboat which had grounded int he mouth of the Appomattox, consisted of six-pounder smooth bore cannon, and were entirely unable to accomplish the destruction of the iron clad craft, although every shot fired struck her. After the battery opened on her, she succeeded in righting herself and replied with some spirit killing two horses and sending several balls through the out houses of Mrs. Wray, on the Chesterfield shore.--Two Federal tugs came to her assistance, but had -ved her only a short distance when she again grounded, and all efforts to remove her were without effect. When last heard from on Monday she was still aground, but six other gunboats had been sent to her protection.
