It began when a Spanish fort opened fire on the United States warship USS Macedonian. Though the ship was damaged, the Americans did not violate their neutrality by counterattacking. On the following day, a boat filled with United States Navy sailors was attacked, resulting in the deaths of two seamen and the wounding of eight others."@en . . .
