It was not until the following spring that the newly formed Central Government at Yedo found itself able to turn its attention seriously to the subjugation of the little band of malcontents up north, and then the Imperial fleet steamed away from the anchorage at the head of the bay, off Shinagawa, intending to rendezvous at Hakodate where the rebels were making a last stand. The chief hope of the Satsuma officers lay in their recent acquisition, the _Stonewall_, to which had been given the Japanese title of _Adzuma_. She had been employed in the American Civil War before she came into Japanese hands, as one of the Federal Squadron in the assault on Vicksburg. The _Adzuma_ though of small tonnage, was an ironclad, and with her mighty ram she presented a most sinister appearance. Altogether the collective fleet made a very good beginning, and the Imperialists were justly proud of it as marking an appreciable advance on the agglomeration of war junks with which the nation’s sea-fighting had been done under the old conditions. The _Stonewall_ (or _Adzuma_) had been bought in America by the agents of the Shogunate, and she dropped anchor in Yokohama on the 24th of April 1868, only a few days before the Prince Tokugawa Keiki resigned his office. She was never delivered to the Shogun’s government, but was, by order of the American Minister, retained in port at Yokohama under the Stars and Stripes ensign, though as a matter of fact she had flown the flag of Japan on her voyage thither from the United States. There was some little heart-burning at this, for it was thought that had she been available for use by the Shogunate party which had bought her, she might with her far greater power have made short work of the imperial fleet. But, as we have seen, the Shogun was then ready to resign, and all prospect of success vanished with his submission to the Emperor five days after the ironclad’s arrival in Japanese waters.
