With the entry of the US into World War I, Theodore Roosevelt began organizing a volunteer force of four divisions. The reaction around the nation was enthusiastic with over 100,000 men volunteering, and many professional officers in the Regular Army seeking to serve with the divisions. Congress authorized the raising of the four volunteer divisions, at the discretion of the President, in the Selective Service Act of 1917. Roosevelt was not named as the commander of the divisions, but everyone knew who this provision was intended for. Wilson quickly decided that he would not authorize the divisions, fearing that Roosevelt would either get killed, in which case he might be blamed, or Roosevelt would return a national hero and be a formidable Republican candidate for the White House in 1920. Wilson’s decision was perhaps the bitterest disappointment in Roosevelt’s life, a disappointment that echoes in his May 21, 1917 letter to his volunteers:
The President has announced that he will decline to permit those divisions to be organized or to permit me to have a command in connection with such a force. After consultation yesterday, personally or by wire, with some of the men who have volunteered to raise units—regiments and battalions—for the divisions, including John C. Groome, of Pennsylvania; Seth Bullock, of South Dakota; John C. Greenway, of Arizona; John M. Parker, of Louisiana; Robert Carey, of Wyoming; J. P. Donnelly, of Nevada; Sloan Simpson, of Texas; D. C. Collier and F. R. Burnham, of California; I. L. Reeves, Frazer Metzger, and H. Nelson Jackson, of Vermont; Harry Stimson, W. J. Schieffelin, and William H. Donovan, of New York, and Messrs. James R. Garfield, Raymond Robbins, R. H. Channing, David M. Goodrich, W. E. Dame, George Roosevelt, Richard Derby and various others who were immediately accessible, it was decided unanimously that in view of the decision of the President the only course open to us is forthwith to disband and to abandon all further effort in connection with the divisions, thereby leaving each man free to get into the military service in some other way, if that is possible, and, if not, then to serve his country in civil life as he best can.
