Book excerpt: In his study of the Vicksburg campaign, the author begins on March 29, 1863, when Ulysses S. Grant made his fateful decision to find an undefended landing spot on the Mississipi shore somewhere to the south of the city. In supporting the idea that the campaign grew out of a maze of interacting political, social, economic, geographic, military, and emotional considerations, he maintains that geography does not define who wins or loses, but only influences the ways in which campaigns and battles are waged. He illuminates the factors which participants weighed in making their decisions, thus providing insight on the decision-making process itself. Annotation copyrighted by Book News Inc., Portland, OR
