Book excerpt: The late Byron Farwell served as an engineer in the British forces of World War II and was an author of at least seven books on various aspects of military history. In this encyclopedia, a labor of love intended for both scholars and general readers, entries include information on wars, revolutions, battles, sieges, spies, soldiers, technical military terms, weapons, and other aspects of 19th-centruy wars and military life. The length of an entry does not necessarily correspond to its importance. Some lesser conflicts and minor personalities are given more space, because information is not readily available elsewhere; and conversely, if information on a topic is widely available, the entry is short. Small bandw images enhance the text. A selected bibliography is included at the end of the volume. Indexing, at least by country or general topic would have improved this otherwise carefully prepared reference. Annotation copyrighted by Book News Inc., Portland, OR
