A card from Gen. Beauregard
Augusta June 21.
--The Mobile Evening News, of the 19th inst., contains a card from Gen. Beauregard denying Halleck's dispatch about Pope's capturing 10,000 prisoners, &c. He says: ‘
"Gen. Pope was careful in his advance after my army had retired from each successive position.
The retreat was conducted with great order and precision, and must be looked upon by the country as equivalent to a brilliant victory.
The actual number of prisoners taken was about equal on both sides, and but few of the enemy were captured.
There were only seven engines taken, and they were damaged.
I attest that all we lost at Corinth would not amount to one day's expense of Halleck's army." ’
