Following the battle of Bussaco on 27 September 1810 Wellington's heavily outnumbered troops began to withdraw towards Lisbon. By the evening of 9 October the British and Portuguese began to withdraw behind a line of defensive works that had been built to the north of Lisbon. These were not the rudimentary field works that the French anticipated, but an enormous network of forts, batteries and redoubts whose construction had been started the previous November the Lines of Torres Vedras. This 30-mile-wide line utilised the area's natural defences, damming rivers, scarping hillsides, blocking roads and establishing forts upon almost all of the hills. This title describes its design, creation and effectiveness in the face of French attacks.

“This is a well-researched, well-written, closely argued and fascinating contribution to the historiography of the Peninsular War.”—The Spectator In 1809 French armies controlled almost every province of Spain and only Wellington’s small force in Portugal stood between Napoleon and the conquest of Iberia. The French invaded Portugal in the summer of 1810, but found their way blocked by the most extensive field fortifications the world had ever seen—the Lines of Torres Vedras. Unable to penetrate the Lines, the French were driven back into Spain having suffered the heaviest defeat yet experienced by Napoleon’s armies. The retreat from Portugal marked the turning point in the Peninsular War and, from the security of the Lines, Wellington was able to mount the offensive campaigns that swept France’s Imperial armies back across the Pyrenees. The Lines of Torres Vedras is an authoritative account of the planning, construction and occupation of the Lines and of the battles, sieges and horrors of the French invasion. It is also an important study of Wellington’s strategy during the crucial years of the war against Napoleon. “Essential reading for every Peninsula enthusiast, this is recommended highly.”—Military Illustrated

With the exception of the key royal sites, such as Stirling and Edinburgh, few Scottish castles were located at strategic points, or were intended to house garrisons required to defend or subjugate towns. Instead they were primarily fortified dwelling houses, erected in an environment of weak Royal authority and endemic feuding between rival clans and groups, in both Highland and Lowland areas. Although some enceinte castles were developed during the 16th and 17th centuries, most defensive construction focused on the tower house, a distinctive vernacular style of Scottish fortification. This book examines the design, development, and purpose of these quintessentially Scottish buildings, and also covers larger sites such as Urquhart and Blackness.

The ring of fortifications protecting the city of Verdun on the Meuse River would become critical in the infamous battle of World War I. This book examines these fortifications, including the famous forts of Douaumont and Vaux that saw some of the fiercest fighting during the battle.

The Philippines were declared an American Territory on January 4, 1899, and fortification construction soon began on the islands in the mouth of Manila Bay. Among the sites built were Fort Mills (Corregidor), Fort Frank, and the formidable "concrete battleship" of Fort Drum. The defenses suffered constant Japanese bombardment during World War II, leading to the surrender of American forces. In 1945 the forts were manned by Japanese soldiers determined to hold out to the bitter end. This title details the fortifications of this key strategic location, and considers both their effectiveness and historical importance.
