Yankee reports of the Siege of Vicksburg.
Our Fredericksburg correspondent sends us the following summary, obtained from the New York Herald, of the 26th inst:From Vicksburg
Cairo, May 25--10 P. M.
--The boats from below had not arrived at Memphis up to nine o'clock to-night.
All the boats at Milliken's Bend have been sent up the Yazoo to meet any possible contingency.
The last positive intelligence came to-day by the North Star, which left the mouth of the Yazoo at 1 o'clock on Thursday.
The battle was still raging, with the land forces in the rear.
Porter's mortar boats above and below were engaged.
It is believed there are a number of women and children still remaining in Vicksburg.
Chicago, May 25--Dates below to the morning of the 22d have been received.
The bombardment of the enemy's upper works by the mortar fleet was continued.
Persons who saw the operations through a glass say they are confident Grant captured a battery on Walnut hill.
A furious cannonading is going on all around.
Dispatches from Washington, of the 25th, say that an officer of Grant's, under date 9 P. M., Friday night, has written a letter confirming previous successes — that 6,000 prisoners and 74 pieces of cannon had been captured.
At the hour when the letter was written McPherson's force, in the centre, was within one mile of the court house at Vicksburg, while Gen. Herman, on the right, and McClernand, on the left, were each within 1½ miles of the town, and the gunboats were shelling in front.
It is believed Grant has nothing to fear from any concentration of forces in his rear.
The destruction of the Big Black bridge will prevent the speedy arrival of the small force Johnston has.
Rear Admiral Porter's official dispatch to Secretary Welles, dated Haines's Bluff, Zazoo River, May 20th, says: ‘
On the 15th he came over the Yazoo to co-operate with Grant.
On the 18th firing was heard in rear of Vicksburg; by the "aid of glasses" saw artillery driving the rebels before them. "I sent steamers up the Yazoo to open communication, and in three hours received letters from Grant informing me of their vast success.
In the meantime I pushed on to Hainesis Bluff, which the enemy had commenced evacuating the day before.
When they saw the gunboats they ran out and left everything.
On the 19th I placed six mortars in position, with orders to fire night and day, as rapidly as they could.
The works at Haines's Bluff are very formidable.
I burned the gun carriages, blew up the magazine, and destroyed the works generally, and then sent Com Wilkes up the Yazoo to Yazoo City to destroy everything.
Grant has closely invested Vicksburg.
The rebels have been completely beaten at all points.
In a few hours the Mississippi will be open." ’
