by Louisiana State, $27.50. The first of two volumes, Mr. Starr’s history follows the development of the federal cavalry from Fort Sumter to Gettysburg—that is, from the status of undesirable stepchild (horses are expensive and Congress hated the thought of them) to useful partner. This rags-to-respectability tale is enlivened by humorous or horrendous anecdotes from the participants, who were probably the most literate soldiers that ever took the field and very nearly the least disciplined. In pursuing their activities, Mr. Starr turns up an enormous collection of odd facts and surprising details. The book is a bonanza for Civil War buffs.
