Book excerpt: Known to posterity as Scottorum Malleus - the Hammer of the Scots - Edward I was one of medieval England's most formidable rulers. In this meticulously researched new history, David Santiuste offers a fresh interpretation of Edward's military career, with a particular focus on his Scottish wars. This is in part a study of personality: Edward was a remarkable man. His struggles with tenacious opponents - including Robert the Bruce and William Wallace - have become the stuff of legend.There is a clear and perceptive account of important military events, notably the Battle of Falkirk, but the narrative also encompasses the wider impact of Edward's campaigns. He attempted to mobilize resources - including men, money and supplies - on an unprecedented scale. His wars affected people at all levels of society, throughout the British Isles.David Santiuste builds up a vivid and convincing description of Edward's campaigns in Scotland, whilst also exploring the political background. Edward emerges as a man of great conviction, who sought to bend Scotland to his will, yet also, on occasion, as a surprisingly beleaguered figure. He is presented here as the central character in a turbulent world, as commander and king.
