The very real threat of the invasion of Britain in 1940 initiated a huge military construction program. Around the vulnerable coasts of the country, as well as inland, were built thousands of pillboxes, anti-tank barriers and other obstacles to defeat or delay the invader. The end of WWII saw much cleared away but sufficient still remains, and this book guides the curious in identifying the remaining defensive structures and features which once formed part of the military landscape. Although, to our eyes, the survivals might seem randomly placed, there was always a considered plan and the book describes how these plans worked. Previously little appreciated, a national project (The Defence of Britain) has now identified many of the sites and there is a growing movement to protect what remains.

The twentieth century ushered in new forms of warfare. On the high seas the submarine would challenge the supremacy of surface craft, and in the air the aeroplane offered new forms of both attack and reconnaissance. The advent of the tank made cavalry redundant and speeded-up the pace of war. Concealment, or the ability to confuse the enemy, could profoundly affect military operations and individual survival. Uniforms became drab for concealment, but in their camouflaged forms could denote elite fighting units. Artists were mobilised to devise concealment and the natural world played its part. Assumptions were made that had to be corrected. This book explains the fascinating challenges of the new ways of warfare and how concealment by camouflage played its part.

Designed to dominate the surrounding area, to house powerful garrisons, offer sumptuous quarters for local nobility, and to discourage and repel enemy attacks, castles dominated England and Wales for more than half a millennium. Though some were built before 1066, the Norman Conquest left a lasting legacy in the form of fortifications ranging from small earthworks now barely discernible, to mighty and dominating stone fortresses. This book examines why castles were so essential to medieval warfare, their importance in domestic politics, and the day-to-day lives of those who lived and worked within them. It also shows how the development of new technologies affected their construction and design, and why they eventually fell into disrepair in the late Middle Ages. Beautifully illustrated with stunning photographs, this is the perfect guide for any castle enthusiast seeking to discover more about medieval fortifications and their inhabitants.
