John Horst traces the adventures of a cast of characters, both real and fictional, who answered the call to put things right in Cuba: Theodore Roosevelt, redefining himself as a soldier and war leader; Jonathan Whelihan, the Arizona wrangler, hungry to prove himself and gain freedom from the bonds of an overbearing father; Rocky Killebrew, Jonathan's adopted brother, struggling with a proclivity for strong drink; Nurse Clara Maass, seeking adventure and fulfillment while serving God and country, and many of the historical personages of this larger-than-life history--Bucky O'Neill, William McGinty, and Black Jack Pershing, among others. John Hay called it -a splendid little war, - but Roosevelt's Boys brings to bear that no war is little, or splendid, regardless of duration or scale.
