Roosevelt was impressed by the insurrection in Cuba, which kept that Island in perpetual disorder. The cruel means, especially reconcentration and starvation, by which the Spaniards tried to put down the Cubans, stirred the sympathy of the Americans, and the number of those who believed that the United States ought to interfere in behalf of humanity, grew from month to month. During his first year in office, Assistant Secretary Roosevelt busied himself with all the details of preparation. And all the while he watched the horizon towards Cuba, where the signs grew angrier and angrier. But the young Secretary had to act with circumspection. President McKinley, desiring to keep the peace up to the very end, would not countenance any move which might seem to the Spaniards either a threat or an insult. Early in the evening of February 15, 1898, the U. S. battleship _Maine_, peaceably riding at her moorings in Havana Harbour, was blown up. Two officers and 264 enlisted men were killed by the explosion and in the sinking of the ship. The next morning, the newspapers carried the report to all parts of the United States, and, indeed, to the whole world. A tidal wave of anger surged over this Country. “That means war!” was the common utterance. I doubt whether Roosevelt ever worked with greater relish than during the weeks succeeding the blowing-up of the _Maine_. The Navy Department arranged in hot haste to victual the ships; to provide them with stores of coal and ammunition; to bring the crews up to their full quota by enlisting; to lay out a plan of campaign; to see to the naval bases and the lines of communication; and to coöperate with the War Department in making ready the land fortifications along the shore. Having accomplished his duty as Assistant Secretary, Roosevelt resigned. He thought that he had a right to retire from that post, and to gratify his long cherished desire to take part in the actual warfare. General Alger, the Secretary of War, had a great liking for Roosevelt, offered him a commission in the Army, and even the command of a regiment. This he prudently declined, having no technical military knowledge. He proposed instead that Dr. Leonard Wood should be made Colonel, and that he should serve under Wood, as Lieutenant Colonel. While Roosevelt finished his business at the Navy Department, Colonel Wood hurried to San Antonio, Texas, the rendezvous of the First Regiment of Volunteer Cavalry--the Rough Riders! A call for volunteers, issued by Roosevelt and endorsed by Secretary Alger, spread through the West and Southwest, and it met with a quick response.
