THE OPPOSING FORCES IN THE VICKSBURG CAMPAIGN.

CONFEDERATE RIVER-BATTERY ON THE RIDGE SOUTH OF VICKSBURG.

General Blair to General Pemberton : ST. LOUIS, January 24, 1874. GENERAL J. C.

PEMBERTON, Fauquier County, Virginia. DEAR GENERAL : I take pleasure, in answer to your letter of the 19th of January, in saying that it was generally understood in our army that General J. Johnston's courier, conveying dispatches to you previous to the battle of Baker's Creek or Champion Hills, betrayed his despatches to General Grant, and also your answers to General Johnston's orders, so that, in fact, General Grant had the most precise information as to your movements and those of General Johnston. I do not know positively from General Grant these facts, but the matter was spoken of by the officers of our army in such a way as to leave no doubt in my mind. Very respectfully, your obedient servant, FRANK P. BLAIR.
