After the fall of Columbus, the next point to which army and navy were to give attention was the famous Island Number Ten. Here the Confederates were concentrating all that were available in men and cannon. Thousands of negroes were at work upon the trenches, and it was believed that the fight would be most desperate. After long waiting for his armament and the training of his men, Commodore Foote was ready. Carleton wrote at Cairo, March 10, 1862, in the exhilaration of high hopes: "Like the waves of the Atlantic is the tide of events. How they sweep! Henry, Donelson, Bowling Green, Nashville, Roanoke, Columbus, Hampton Roads, Manassas, Cedar Creek,--wave upon wave, dashing at the foundation of a house built upon the sand. ... The gigantic structure is tottering. A few more days like that of the immediate past, and the Confederacy will have a name and a place only in history. And what a history it will be! A most stupendous crime. A conspiracy unparalleled, crushed out by a free people, and the best government of all times saved to the world! How it sends one's blood through his veins to think of it! Who would not live in such an age as this? Before this reaches you, the telegraph, I hope, will have informed you that the Mississippi is open to New Orleans." So thought Carleton then. Who at that time was wiser than he? Island Number Ten, so named quite early in history, by the pilots descending the river, was a place but little known in the East. To the writer it was one of interest, because here had lived for a year or so a beloved sister whose letters from the plantation and home at which she was a guest were not only frequent, but full of the fun and keen interest about things as seen on a slave plantation by a bright young girl of twenty from Philadelphia. Well do I remember the handsome planter of commanding form and winning manners who had made my sister's stay in the family of the Merriwethers so pleasant, and who at our home in Philadelphia told of his life on the Mississippi. This was but two or three years before the breaking out of the war. This same plantation on Island Number Ten was afterwards sown thickly with the seed of war, shot, and shell. In front of it took place the great naval battle, which Carleton witnessed from the deck of the gunboat _Pittsburg_, which he has described not only in his letters but also in the books written later. After the destruction of the rebel fleet followed the heavy bombardment which, after many days of constant rain of iron, compelled the evacuation of the forts early in April. Even after these staggering blows at the Confederacy, Carleton expatiated on the mighty work that yet remained to be done before Secessia should become one of the curiosities of history in the limbo of things exploded.
