In a personal account, the adventures of Bob Hayden, Sheridan's flagman in the Civil War, have been given the swift pace and vivid color of the campaigns in their many moods and movements, by Mr. Catton's practised hand. Enlisting at 17, Bob was a runt of a fellow and had his difficulties toughening up in cavalry training (which he relates with a yarn teller's vim) before being detailed to the fiery Sheridan's outfit. Though he had always admired Sheridan, Bob's awe and esteem are doubled when the general makes him his flagman and the boy's own story reflects a portrait of Sheridan, the man who seemed to win battles by sheer will power. There is a close following of the Kentucky and Virginia campaigns- the defeats and victories- and further, of Bob's romance with the Shenand Valley girl, Lavinia, whose sentiments turn towards the North and whose spying helps the victory at Cedar Creek. Good historical fiction but as in the others in Doubleday's Cavalc series, this seems written to order.
