Advancing from this point General Lawton, commanding a division of infantry, moved parallel to the shore and seized Siboney. General Wheeler, a former Confederate who was now in command of the cavalry, met and defeated a Spanish force at Las Guasimas. Further advance met difficulties that were more serious. On the left of the American line was San Juan Hill, an eminence which commanded the country toward the east; on the right was El Caney, a fortified village held by a small force of Spaniards. The country between the two points was a jungle, the roads hardly better than trails, where troops frequently had to go in single file. The fight at El Caney was severe, the enemy being well-entrenched, well-armed and protected by wire entanglements and block houses, and General Lawton suffered a loss of more than 400 killed and wounded before driving the Spaniards out of their position. San Juan Hill was still more stubbornly defended, and an American advance was impeded by the heat, the tropical growth and the uneven character of the country. Under these circumstances officers became separated from their men and victory was gained through the determination and resourcefulness of the individual. The Spaniards then fell back upon Santiago. [Illustration: Campaign about Santiago] The continued success of the Americans compelled the Spanish authorities to make an immediate decision in regard to the fleet. To remain in the harbor seemed to mean being encircled and starved; to go out through the narrow channel seemed to lead to sure destruction. Yet the latter venture appealed to the commander-in-chief of Cuba, Captain-General Blanco, as the more honorable one and on July 2 orders were sent to Admiral Cervera to make the attempt. Early next morning, while Admiral Sampson was away at a conference with General Shafter, lookouts on the American battleships descried the _Infanta Maria Teresa_ feeling her way out of the harbor, followed by the remainder of the Spanish fleet, three armored cruisers and two torpedo-boat destroyers. The Americans instantly closed in, directing their fire first against the _Teresa_ and later against the rest of the fleet as they tried to follow their leader out to safety. Once out of the harbor the entire Spanish fleet dashed headlong toward the west, parallel to the coast, while the Americans kept pace, pouring a gruelling fire from every available gun. The Spaniards returned the fire and thus "the action resolved itself into a series of magnificent duels between powerful ironclads." One by one the enemy's vessels were sunk or forced to run ashore--the _Cristobal Colon_ last, at two o'clock in the afternoon. The Spanish losses, besides the fleet, were 323 killed and 151 wounded; the Americans lost one killed and one wounded. The city of Santiago, deprived of its fleet, found itself in a desperate plight and surrendered on July 16. Shortly afterwards General Miles led an
