Book excerpt: From the thirteenth to the sixteenth centuries, outlaws reigned supreme on the contentious frontier between England and Scotland. Feud and terror, raid and reprisal, were the ordinary stuff of life—and a way of survival. Power was held by the notorious border reivers (the "steel bonnets," named for their flashy helmets), who robbed and murdered in the name of family: the famous clans (or "grains")—like Elliot, Armstrong, Charlton, and Robson—romanticized by Sir Walter Scott. In The Steel Bonnets, George MacDonald Fraser, author of the bestselling Flashman novels, and himself a borderer, tells the fascinating and bloody story of the reivers, their rise to power as ferocious soldiers of horse, and their surprisingly sudden fall from grace.
