Books by Mike Osborne

Dr Mike Osborne's interest in fortification began with childhood visits to castles, and has developed over the years to include all aspects of the topic, from Iron-Age forts to Cold War bunkers. He was a volunteer-coordinator for the Defence of Britain Project, recording the military structures of the twentieth-century, and, after a thirty-year-career in education, took early retirement. Since then, he has produced nearly twenty books on topics that range from Civil War sieges and fortifications, to drill halls and twentieth-century military structures. He has also written a series of county surveys of defences, as well as the best-selling Defending Britain.
