The most important event in the early history of the war, and the event that controlled the movements of the Red Cross steamer _State of Texas_, as well as the movements of General Shafter's army, was the arrival of the Spanish fleet of cruisers and torpedo-boats at Santiago de Cuba on May 19. There had been skirmishes and bombardments before that time, at Matanzas, Cardenas, and various other points on the Cuban coast; but none of them had any strategic importance, or any particular bearing upon the course or the conduct of the war. It was the appearance of Admiral Cervera at Santiago which determined the field of action, and, to some extent, the plan of campaign. The invasion of eastern Cuba had already been under consideration, and when the Spanish fleet took refuge in Santiago harbor the President and his counselors decided, definitely and finally, to begin operations at that end of the island, and to leave the western provinces unmolested until fall. The regular army, it was thought, would be strong enough, with the aid and coöperation of Admiral Sampson's fleet, to reduce the defenses of Santiago, and the volunteers might be left in camp at Chickamauga, Tampa, and Jacksonville, to get in training for an attack upon Havana at the end of the rainy season.
The preparations for the invasion of Cuba seemed, at that time, to be nearly, if not quite, complete. The whole regular army, consisting of seven regiments of cavalry, twenty-two regiments of infantry, and fourteen batteries of artillery, had been mobilized and transported to the Gulf coast; the quartermaster's department had, under charter, twenty-seven steamers, with a carrying capacity of about twenty thousand men; immense quantities of food and munitions of war had been bought and sent to Tampa, and there seemed to be no good reason why General Shafter's command should not embark for Cuba, if necessary, at twenty-four hours' notice.
On May 26, just a week after the appearance of Admiral Cervera and his fleet at Santiago, the President held a consultation at the Executive Mansion with the Secretary of War, the Secretary of the Navy, and the members of the Board of Strategy, and decided to begin the invasion of Cuba at once. Orders were presumably sent to General Shafter to prepare for an immediate movement, and Secretary Long telegraphed Admiral Sampson as follows:
