"On the Blockade" is the third historical fiction novel in the "The Blue and the Gray Series." Like the first and second volumes, the plot dates back to the War of the Rebellion, and takes place in the midst of scenes on the Southern coast, where the United States naval operations occurred. Many of the personages of the preceding volumes have been introduced in the present one, and the central figure remains the same. [Cover title varies: "The Blue and the Grey Afloat on the Blockade."]
