COPYRIGHT, 1911, REVIEW OF REVIEWS CO.] This craft, the "Commodore Perry," was an old New York ferryboat purchased and hastily pressed into service by the Federal navy to help solve the problem of patrolling the three thousand miles of coast, along which the blockade must be made effective. In order to penetrate the intricate inlets and rivers, light-draft fighting-vessels were required, and the most immediate means of securing these was to purchase every sort of merchant craft that could possibly be adapted to the purposes of war, either as a fighting-vessel or as a transport. The ferryboat in the picture has been provided with guns and her pilot-houses armored. A casemate of iron plates has been provided for the gunners. The Navy Department purchased and equipped in all one hundred and thirty-six vessels in 1861, and by the end of the year had increased the number of seamen in the service from 7,600 to over 22,000. Many of these new recruits saw their first active service aboard the converted ferryboats, tugboats, and other frail and unfamiliar vessels making up the nondescript fleet that undertook to cut off the commerce of the South. The experience thus gained under very unusual circumstances placed them of necessity among the bravest sailors of the navy. [Illustration: THE LAST PORT CLOSED COPYRIGHT, 1911, PATRIOT PUB. CO.] Fort Fisher, captured January 15, 1865. With the capture of Fort Fisher, Wilmington, the great importing depot of the South, on which General Lee said the subsistence of his army depended, was finally closed to all blockade runners. The Federal navy concentrated against the fortifications of this port the most powerful naval force ever assembled up to that time--fifty-five ships of war, including five ironclads, altogether carrying six hundred guns. The upper picture shows the nature of the palisade, nine feet high, over which some two thousand marines attempted to pass; the lower shows interior of the works after the destructive bombardment.
