Harriet Tubman, Secret Agent: How Daring Slaves and Free Blacks Spied for the Union During the Civil War
Starred Review.Grade 5–8—This small book contains a lot of fascinating information on the network of slaves and free blacks who advanced the Union cause during the Civil War. The narrative is framed by the story of Harriet Tubman, the ex-slave and conductor of the Underground Railroad, whose work to help others escape is well known; less is known about her role as a spy. Tubman assisted Northern troops by tapping into a group of ex-slaves working in the South and passing information on to the Union forces. According to Allen, she led a raid along the Combahee River and may have led other expeditions as well. Readers also meet other people who participated in the espionage, including Elizabeth Van Lew, who devised a numerical code to transmit information that she picked up at society gatherings. Using this code, which is described in an appendix, the author includes several messages in the book. The type font and black-and-white reproductions and maps greatly enhance the presentation; in addition to illustrations from traditional sources, such as the Library of Congress, there are quality originals. A great addition to any collection.—Elizabeth M. Reardon, McCallie School, Chattanooga, TNCopyright © Reed Business Information, a division of Reed Elsevier Inc. All rights reserved.
