Don Lopez had tried to remain faithful to the Spanish King and crown, until the cruelty of Weyler had driven him to side with the downtrodden insurrectos and with money and influence furnish them with arms. Ametza, his dark-eyed, beautiful daughter, is courted by El Donza, who, by courtly manner and courtesy, has covered his identity as a Spanish agent from the father and won liking from Ametza. About this time a terrific storm on the sea throws two American soldiers of fortune on the beach of Cuba near the home of the Lopez. Ametza by chance sees them and getting aid rescues them. Ametza’s attentions to the Americans causes El Donza to swear vengeance against them, and his anger is added to by a good American thrashing from Harold Logan. Going back to the Spanish camp, he gets his henchmen and determines on an attack of the Lopez home. A skirmish occurs and the timely action of Ametza saves Harold from death, but her father and sister fall victims of Donza’s vengeance. Ametza and the two soldiers of fortune escape from the Spanish and reaching the rocky shore, see the grand old flag fluttering from an American gun boat. The officers see the signal of distress made by them and send a small detachment ashore. Meanwhile El Donza has reached the shore, being told of the Americans’ escape by a Spanish spy and pursues the Americans. The marines land, but are insufficient to cope with the Spanish. The battle results in the capture of Harold, Sherman and Ametza, who are taken to prison. In prison the Americans are offered the choice of being branded with a hot iron, or allegiance to the Spanish flag. Sherman is branded, but ere the iron reaches Harold, Ametza sets the prison on fire and the guards rushing to subdue the flames, the Americans escape. Reaching the American scouts, they are conveyed to the American camp. A battle is imminent and a Spanish scout reports to El Donza, who has escaped the flaming prison, their line of march. The Spanish dig pitfalls; but the Americans, by chance, change their route and attacking the Spanish from an unlocked for quarter, rout them and El Donza falls a victim to his own pitfalls Harold raises Old Glory to the accompaniment of American cheers, over the Spanish block house and Ametza and victory are his.
