Theodore Roosevelt could have little effect upon the material preparedness of the United States for the struggle which it was ultimately to enter. But he could and did have a powerful effect upon the spiritual preparedness of the American people for the efforts, the trials, and the sacrifices of that struggle. No voice was raised more persistently or more consistently than his. No personality was thrown with more power and more effect into the task of arousing the people of the United States to their duty to take part in the struggle against Prussianism. No man, in public or private life, urged so vigorously and effectively the call to arms against evil and for the right. His was the "voice crying in the wilderness," and to him the American spirit hearkened and awoke. At last the moment came. Roosevelt had but one desire and one thought. He wanted to get to the firing-line. This was no impulse, no newly formed project. For two months he had been in correspondence with the Secretary of War on the subject. A year or more before that he had offered, in case America went into the war, to raise a volunteer force, train it, and take it across to the front. The idea was not new to him, even then. As far back as 1912 he had said on several different occasions, "If the United States should get into another war, I should raise a brigade of cavalry and lead it as I did my regiment in Cuba." It never occurred to him in those days that a former Commander-in-Chief of the United States Army, with actual experience in the field, would be refused permission to command troops in an American war. The idea would hardly have occurred to any one else. But that is precisely what happened.
