On the morning of April 22d, a squadron under the command of Acting
Rear-Admiral Sampson sailed from Key West to establish a blockade of

Some of our large passenger steamships had been appropriated by the
Government for war service, and did good work for the blockade, as
they can move very fast. They flew about from place to place as
"scouts" or "spies"; they carried messages; they cut the Spanish
cables under water, and were useful in other ways.

The gunboat Nashville sailed from Key West with the squadron, and

the United States and Spain. The Spaniard was not inclined to stop,
and it required another shot before she would stop her engines. The
Nashville sent an officer in a boat to inform the steamer that she was
a prize to the United States. She was found to be a Spanish
