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.
