These ships had their baptism of fire in the naval Battle of Santiago de Cuba, where despite the efforts of
Fernando Villaamil were incorrectly used.
Pluton and
Furor were present at the battle while
Terror had suffered damage prior to arriving at
Cuba and had returned to
Puerto Rico. After the
Spanish–American War began, the
American fleet planned to
blockade the Spanish ships in the Bay of Santiago de Cuba and expected a favorable outcome through the use of ground forces which would allow the entire Spanish fleet to be captured intact. To this end the American fleet tried blocking the entrance to the bay of Santiago by sinking the old
collier Merrimack, but was intercepted by the
cruiser and
Pluton, who managed to sink it before it blocked the canal. The Spanish fleet was outnumbered and outgunned by the encroaching American fleet and would have to try to run through the gauntlet of American ships to escape. Captain Villamil, in charge of both
Pluton and
Furor, proposed to launch a surprise night attack with torpedoes but was overruled by the ranking Admiral
Cervera. On the morning of July 3, 1898, behind the
protected cruiser , the Spanish fleet attempted to run the blockade and escape from Cuba. Charging against a clearly superior force, in which there were three
battleships, an
armored cruiser, and two protected cruisers, the fleet suffered major damage in a short period. With the limited artillery aboard
Pluton and
Furor they could do little against the enemy.
Furor sank quickly at 10:50 with Villamil aboard. His body was never recovered. Meanwhile,
Pluton was
run aground at 10:45 near
Cabanas Bay. The two destroyers would lose of their crew.
Terror was repaired on June 12, 1898, at the port of
San Juan, Puerto Rico. The port at the time was being blocked by the US auxiliary cruiser
USS Saint Paul. On June 22, 1898,
Terror made an exit along with the unprotected cruiser with the intention of attacking the American ship. When
Terror was at an optimal distance for a torpedo attack, she suffered a direct impact from an artillery shell which, although it did not explode, breached the ship's hull, forcing it to retreat protected by the artillery fire of the Isabel II. == Ships of the class ==
