An excellent introduction to the basics of algebraic number theory, this concise, well-written volume examines Gaussian primes; polynomials over a field; algebraic number fields; and algebraic integers and integral bases. After establishing a firm introductory foundation, the text explores the uses of arithmetic in algebraic number fields; the fundamental theorem of ideal theory and its consequences; ideal classes and class numbers; and the Fermat conjecture. 1975 edition. References. List of Symbols. Index.

For most of World War II, British tank development remained faithful to the design philosophy inaugurated during World War I. Experiences in North Africa highlighted flaws in this basic design, however, and the General Staff identified the need for a new heavy cruiser that could combine speed and manoeuvrability with increased armour and armament. The Cromwell Cruiser tank was designed as a result and soon proved itself one of the fastest and most successful tanks deployed by the Allies during World War II.

Air power is the dominant form of military power projection in the modern world. Meilinger has posited a group of challenging propositions that will instill an appreciation for air power for those who seek to understand it and challenge the assumptions of those who do not yet appreciate what it offers. The booklet provides an explanation for each proposition.

During the Napoleonic Wars the region of Hesse was divided between Hessen-Kassel and Hessen-Darmstadt. Under Napoleon's patronage, in 1806 Hessen-Darmstadt received all remaining imperial possessions within its borders and was elevated to a Grand Duchy. That same year, Hessen-Kassel, under Imperial Elector Wilhelm I, was dissolved and incorporated into Jerome Bonaparte's Kingdom of Westphalia, resulting in significant political, administrative and sartorial changes.

Mercenaries were a common feature throughout most of Europe in the 14th and 15th centuries, and had been known far earlier. But nowhere did such a sophisticated system of hiring, payment and organisation of mercenaries develop as it did in Italy. The condottiere – whose name came from the condotta or contract between himself and his employer – was the result.

Though the 'Scythian period' in the history of Eastern Europe lasted little more than 400 years, the impression these horsemen made upon the history of their times was such that a thousand years after they had ceased to exist as a sovereign people, their heartland and the territories which they dominated far beyond it continued to be known as 'greater Scythia'.

Although light infantry tactics formed one of the cornerstones of Napoleonic warfare, their employment was by no means restricted to Light regiments. Thus, from the early 1800s if not before, the distinction between Light and Line infantry was largely one of costume and tradition. One marked difference from the Line infantry, however, was in the superior esprit de corps of the Light regiments.

The concept of the bodyguard is as ancient as the practice of an individual assuming the leadership of a group or tribe. From the Companions of Alexander to the Varangians of Byzantium, bodies of elite warriors, owing personal allegiance to their sovereign and obeying no others, have illuminated or stained the annals of military history.

This book examines the development, deployment and design of armoured vehicles during the Middle East wars of the late 20th century. Operation `Kadesh', the Six-Day War and the Yom Kippur war are all covered. Vehicle colours and markings are shown in full colour artwork.

The Space Shuttle is one of the oldest and most famous manned launch systems – the only launch vehicle that has been used for a longer period of time is the Soviet (now Russian) R-7 booster. By the start of the third millennium, the Space Shuttle had carried crews into space over 85 times. Although not a military structure, the Shuttle had been sold as an all-purpose launch system to be used jointly for military and civilian purposes. Featuring full-colour photos throughout, this book covers the design, development and operational history of a unique vehicle.

From the Back Cover Oren Barak sheds new light on the major political and social developments in Lebanon since its independence by focusing on the emergence of the Lebanese Army, its paralysis during the civil war from 1975 to 1990, and its reconstruction after the war. He discusses the remarkable transformation of a military dominated by one sector of society--the Christian communities, and particularly the Maronites--into one that is characterized by power sharing among Lebanon's various communities, large families, and regions.
