Relying heavily on firsthand accounts plus uncredited (but apparently contemporary) photos, prints and sketches, Murphy opens and closes with the battlefield dedication ceremony, in which Edward Everett delivered a long, eloquent speech and President Lincoln was tentatively invited to give ``a few appropriate remarks'' (quoted in full); in between, the author analyzes Lee's strategy; points out the many ironies of timing and position that affected the battle's outcome; and, using brief extracts from the journals of a Union corporal and a Confederate lieutenant, captures a soldier's-eye view of the exhausting marches, frantic firefights, and weary, poignant aftermath. Readers will get a good sense of what generals and privates, countryside and battle looked like from the many b&w illustrations, and a general idea of troop movements from a set of sketchy maps. A realistic alternative to Neil Johnson's Battle of Gettysburg (1989), which is illustrated only with photos of a modern reenactment. Capacious bibliography; index. (Nonfiction. 11-14)
