Taking particular care not to damage the city beyond the waterfront, the American gunners directed their gunfire solely at the Spanish ships and took a heavy toll of the steamers congregated there. Spanish supply steamer "Purissima Concepcion" caught fire alongside a dock and sank at her moorings; gunboat "Maria Ponton" blew up when her magazines exploded; gunboats "Estrella" and "Delgado Perrado" also burned and sank while two transports, "Gloria" and "Jose Garcia", went down as well. Two small gunboats, "Guantanamo" and "Guardian" were driven ashore and shot to pieces.
