O• Tide iBomdafdmcni of Fort Pillow.’■ [From tho Chicago Journal J ’ •. On THEfc MISSISSIPPI, RlVBfy Above Island No.‘33; April 17, 1862I arrived here yesterday onexrf the transports, and foiind the guhboat and mortar fleet ‘‘blasting away” at the rebel works on tho TeunoBseo. shore, known as Fort £illpw or Fort Wright .Our flotilla consists pf eight gunboats—the Benton, Carondelet, St Louis, Pittsburg, Cincinnati, Cairo, Mound City and Conestoga, a half dozen mortar boats, and the stoam, transports loaded with ammunition and stores. ’ Five rebol gunboats were discovered here when our fleet approached, which wero speedily driven away alter firing a few shots. 0.The firing between tho. fortifications and our gunboats and mortars has been in progress at iutervala since Monday. As yet no damage has been done to our fleet, but the enemy have suffered considerably, many of our big shells taking good effect on their works. The fort is located on a bend in tho river, and wp may have many of the same difficulties to work against that embarrassed our operations at Island No. 10, but it is only a question of time when the. rebels will be driven out of their intrenchments, or be captured. These fortificatiohs (for there is a series of them) are said to extend down tho river bank for several miles to Fort Randolph, which is represented as a formidable position.. Our boat Information places the number of the garrison at Fort Pillow at5,000t and at FortRandoIph at 3,000. One Gen. Villipigus (pronounced vily pig) is in command at Pillow, Who he is, or what he amounts to, I cau't say, never before having hoard the name.Commodore Foote is confident of success here—“by patient pcrsevercnce, it may be, but successful surely.” Little is known of tho rebel means of resistance, but the goneral opinion is that they will not be able to hold Out more than a few days at the most, and that we will be in possession of Forts Pillow and Randolph by next week, and in one week more our guns will be pounding away againHt the walls of the other Fort Pillow near Memphis, which, according to all that we can ascertain, is the strongest of the enemy’s river fortifications.Passing down, we found all quiet at Island No. 10 yesterday. Colonel Hogg’s 15th Wisconsin regiment is quartered there.The weather down here at present is as warm as it is in Chicago in Juno. It is uncomfortably hot a pbrtioo of the time, and the sand flies are^ very troublesome during the day, and at night the mosquitos nearly devour us. The glories of war, even to a reporter, are not without a dark side of the picture.Y
