The American Civil War saw a massive development in the use of field fortifications, the result of the practical application of antebellum West-Point teaching, and the deadly impact of rifled infantry weapons and artillery. Both the Federal and Confederate armies began to develop far more sophisticated systems of field fortification, and the larger field works and fortifications surrounding Washington, DC and Richmond, VA were redesigned and rebuilt several times. This volume explores the role of land and field fortifications in the eastern and overland campaigns of the Civil War between 1861 and 1865. Particular attention is devoted to the nine-month siege of Petersburg, where daily life within the redoubts, lunettes, redans, bomb-proofs, trenches and rifle pits is vividly described.

This second volume about Japan's samurai commanders covers the generals of the later years of the Age of the Warring States (Sengoku period), a period when only the most able leaders survived. This was a time when the prowess of a commander was measured as much by his strategic and organizational abilities as by his individual fighting skills and he was expected to give as great a show of strength in the council chamber as on the battlefield. This book discusses the lives, battles and wider roles of talented commanders such as Oda Nobunaga and Toyotomi Hideyoshi - great men who stood out prominently due to their elaborate suits of armour and helmets, their stunning personal heraldry and their great armies.

Osprey's examination of Samurai commanders during the Gempei Wars (1180–1185), the Onin War (1467–1477), and the early Sengoku period. The samurai were the military elite of medieval and early modern Japan, and the men who led them were hailed as the very greatest, most heroic and most honourable of all samurai warriors. This first of two books examines the lives, equipment, battles and wider roles of the samurai commanders between 940 and 1576, the period from the emergence of the samurai to the triumph of Oda Nobunaga, who set Japan on the road to reunification. The styles of armour and weaponry of the samurai changed considerably during this time and this book visually recreates some of the most famous samurai commanders, such as Taira Masaka (c. 903-940), Minamoto Yorimasa (1106-1180), and Takeda Shingen (1521-1573).

On December 7, 1941, the Japanese Navy launched a surprise attack on American military bases in Pearl Harbor, Hawaii. Masterfully planned and executed, the attack devastated the US Pacific Fleet; in less than two hours, Japanese aircraft had sunk or damaged all eight US battleships anchored in the harbor and had destroyed 151 planes. Thrust into battle, the United States could have only one response: war. DAY OF INFAMY portrays the attack that drove the United States into World War II in full-color, historically-accurate comic book narrative. Featuring the personal stories of front-line heroes like Ken Taylor, George Welch, and mess attendant Dorie Miller, DAY OF INFAMY also provides rich background material – causes and consequences, key players, and a glossary of terms – as well as a list of additional resources that encourages readers to delve further into the time period. DAY OF INFAMY is the ultimate way to experience how Pearl Harbor unfolded and to introduce a lifelong passion for reading.

The history of US light tanks during World War II is a chequered one. The Light Battalions of US Armored Divisions were initially filled with M3A1 and M5 Stuart tanks, however, on the battlefields of North Africa it was realised that these were disastrously under armoured and gunned, and a replacement, or the abandonment of light tank doctrine, was desperately needed. It wasn't until the last few months of WWII that the M24 Chaffee came into service and it was extensively used in combat from the Battle of the Bulge to the final campaigns in Germany. This book will trace the history of this design, its combat record in World War II, its many variants, and its extensive combat record post 1945.

This volume is the second half of the story of the French artillery during the Revolutionary and Napoleonic Wars. It covers the howitzers, mortars and large siege (16- and 24-pdrs) and garrison (8- and 12-pdrs) guns, placing a special emphasis on their role, technical significance and operational use. The introduction of the Gribeauval system put in place a collection of mortars and large guns that were lighter and more manageable than those previously used, while offering first class hitting power.

From 1947 the United States committed herself to the containment of communist expansion, through what became known as the Truman doctrine. From that date, until the early 1990s Britain and other Western powers became locked in a political game of bluff that became known as the Cold War. How fast memory fades ... Only 10 years on the Cold War is political history and the military bases, bunkers, intelligence posts, antennae, aircraft shelters and associated paraphernalia of conflict are deserted and decaying. This unique book reflects a project mounted by English Heritage to document the physical remains of Britain's cold war policies, before they are demolished or reused. The authors describe and discuss the secret offices beneath British cities, the mock villages used to train troops, the now-deserted dockyards where nuclear submarines were constructed, and the 1200 ft wide 'elephant cages' which listened to Soviet whispers from afar. The physical remains are constantly put into the context of political and social change by the authors, making this book fascinating reading for anybody interested in the immediate past.
