The relationship of England and Scotland became defined by events on 9 September 1513 in a battle of great size, bloodshed and finality - the Battle of Flodden.On the back of historian George Goodwin's critically acclaimed debut, FATAL COLOURS, comes FATAL RIVALRY, providing the first in-depth examination of the Battle of Flodden, the biggest and bloodiest in British history.This book captures the importance of the key players in the story - the kings and their respective queens, their nobles, diplomats and generals - as the rivalry brought the two countries inexorably to war. Fatefully, it would be an error by James, that most charismatic of commanders, and in the thick of engagement, that would make him the last British king to fall in battle, would condemn the bulk of his nobility to a similarly violent death and settle his country's fate.
