With his usual luck, that is, the result of intelligence and energy which left nothing to mere luck, Carleton stood on the steamer _Nantasket_, off Charleston, April 7, 1863. Both admiral and general had recognized the war correspondents as the historians of the hour. At half past one, the signal for sailing was displayed from the flag-ship. Then the ugly black floating fortresses moved off in a line, each a third or a half a mile apart, against the masses of granite at Sumter and Moultrie, and the earthen batteries on three sides. "There are no clouds of canvas, no beautiful models of marine architecture, none of the stateliness and majesty which have marked hundreds of great naval engagements. There is but little to the sight calculated to excite enthusiasm. There are eight black specks, and one oblong block, like so many bugs. There are no human beings in sight,--no propelling power visible." A few minutes later, "the ocean boils." Columns of spray are tossed high in air, as if a hundred submarine mines were let instantly off, or a school of whales were trying which could spout highest. There is a screaming in the air, a buzzing and humming never before so loud. "You must think the earth's crust is ruptured, and the volcanic fires, long pent, have suddenly found vent." "There she is, the _Weehawken_, the target of probably two hundred and fifty or three hundred guns, at close range, of the heaviest calibre rifled cannon, throwing forged bolts and steel-pointed shot turned and polished to a hair in the lathes of English workshops, advancing still, undergoing her first ordeal, a trial unparalleled in history. For fifteen minutes she meets the ordeal alone." Soon the other four monitors follow. Seventy guns a minute are counted, followed by moments of calm, and scattering shots, but only to break out again in a prolonged roar of thunder. In the lulls of the strife, Carleton steadied his glass, and when the southwest breeze swept away the smoke, he could see "increasing pock-marks and discolorations upon the walls of the fort, as if there had been a sudden breaking out of cutaneous disease." We now know, from the Confederate officers then in Fort Sumter, that the best artillery made in England, and the strongest powder manufactured in the Confederacy, were used during this two and a half hours of mutual hammering, until then unparalleled in the history of the world. Near sunset, at 5.20 P. M., signals from the flag-ship were read; the order was, "Retire."
