James Grant (1822–1887) was a Scottish author and was born in Edinburgh, Scotland, and was a distant relation of Sir Walter
Scott. He was a prolific author, writing some 90 books, including many yellow-backs. Titles included Adventures of an Aide-de-camp, One of 'The Six Hundred', The Scottish Musketeers and The Scottish Cavalier.

Medieval Warfare collects Grant's work on the subject, from the Battle of Hastings in 1066 to the Battle of Barnet in 1471, a decisive engagement in the Wars of the Roses. The book contains remarkably detailed accounts of many key battles from the period including the Battle of the Standard and Bannockburn to Poitiers and Agincourt from the Hundred Years' War. The historically defining strategies employed during these battles are explored throughout.

Illustrated with vivid portraits of battle and detailed drawings of the tools and weapons of the period, this is the definitive account of a trying and bloody period in history.
