In the year 1296, Edward I of England launched a series of vicious raids across the Anglo-Scottish Border in his attempt to annexe Scotland. The Scots retaliated and the two countries were plunged into 300 years of war in which the Borderland became the frontline and raiding, or "reiving," encouraged by both sides, became a way of life. Keith Durham examines the Border fortresses, ranging from small, well-defended castles to imposing tower houses, or "peles," and a variety of fortified farmhouses known as "bastles." He also investigates the many churches that were strengthened against attack and in times of trouble served as sanctuaries for their congregations.
