Josh Gregory gives a concise summary of the events that lead up to, and leaders who shared in, one of the pivotal conflicts of the Civil War.  He provides an unbiased look at both Union and Confederate leaders and decisions.  After descriptions of events, a map is included to illustrate the proceedings of the three day battle.  The layout is pleasing and attention getting.  Every page has an illustration or an additional information box.  Although the reader level is about 6th grade, learners from upper elementary to middle school will find useful information.  Included are two pages of influential people, a timeline, internet links to primary sources, books, websites, a glossary, and a comprehensive index.
