There have been many books on Theodore Roosevelt, but there are none that solely focus on the last years of his life. Racked by rheumatism, a ticking embolism, pathogens in his blood, a bad leg from an accident, a bullet in his chest from an assassination attempt, in the last two years of his life from April 1917 to January 6, 1919 he went from the great disappointment of being denied his own regiment in World War I, leading a suicide mission of roughriders against the Germans, to the devastating news that his son Quentin had been shot down and killed over France. Racked by grief and guilt, marginalized by world events, the great glow that had been his life was now but a dimming lantern. But TR¿s final years were productive ones as well: he churned out several ¿instant¿ books that promoted U.S. entry into the Great War, and he was making plans for another run at the Presidency in 1920 at the time of his death. Indeed, his political influence was so great that his opposition to the policies of Woodrow Wilson helped the Republican Party take back the Congress in 1918. However, as William Hazelgrove points out in this book, it was Roosevelt¿s quest for the ¿vigorous life¿ that, ironically, may have led to his early demise at the age of 60. `The Old Lion is dead,¿ TR¿s son Archie cabled his brother on January 6, 1919, and so, too, ended a historic era in American life and politics.
