Gr 5-8-Straightforward, simple presentations of two fascinating facets of military history. The first book begins with a chapter on tank warfare at the end of World War I, and then focuses on Germany's panzer tank divisions in World War II. The second title tells the story of Britain's attempts to-well, sink the Bismarck. Both volumes include two or more black-and-white photographs or reproductions per chapter and three color maps. The writing is often a bit limp, but easy to follow. Unfortunately, without source notes readers have only McGowen's word that after World War I the older British Army officers "scoffed at the idea" of tanks being used as main weapons, and are left to wonder if Churchill actually did exclaim to navy commanders, "You must sink the Bismarck!" Still, the books should inspire youngsters to pursue their interest in the subject and find other, better titles such as Donald Knox's Death March: The Survivors of Bataan (Harcourt, 1983) or Stephen Ambrose's Citizen Soldiers (S & S, 1997). Libraries owning Robert Ballard's Exploring the Bismarck (Scholastic, 1991) may not need another book on the topic.-Herman Sutter, Saint Pius X High School, Houston, TX Copyright 1999 Cahners Business Information.
