Important guerrilla Successes in Tennessee.
Mobile, Aug. 10.
--A special dispatch to the Tribune, from Grenada, 9th inst., says that the Memphis Bulletin, of the 7th, states that the Confederates have inaugurated guerrilla warfare in Arkansas on an extensive scale, and mentions several brilliant exploits.
On Sunday they attacked two Yankee regiments, dispersing them completely, capturing sixty wagons of provisions and over three hundred stolen negroes.
Twenty-seven of the latter escaped the same day. They bagged another party near Jacksonport, killing seventeen and capturing twenty wagons of provisions.
Ninety more were attacked near Helena and nearly annihilated, only two escaping. The Governor of New York has officially announced his determination to draft.
A serious rebellion is reported among the Mormons, which, it is teared, will result in war with the Federal Government.
