IN this biography Mr. Hamilton traces the career of Zachary Taylor up to the end of the campaign in Mexico, which was to make him a national figure and President of the United States. Presumably a second volume by the same author will round out the story. Mr. Hamilton has done a scholarly, careful, and well-documented job, and it is not perhaps his fault that his book fails in convincing this reader, at any rate, that Zachary Taylor was anything but a second-rate soldier who did not deserve the position credited him in American history. The author treats him throughout as a hero and nowhere attempts a dispassionate summing up of his qualities and performances. R. E. D.
