In History Today, George Goodwin reviews A Great and Glorious Adventure: A Military History of the Hundred Years War by Gordon Corrigan:
As Corrigan explains, the Hundred Years War extended over a longer period (1337-1453) than its name suggests, but then it was not a continuous war either. Instead its series of intermittent campaigns featuring major battles and sieges was interspersed with periods of lower tempo siege warfare and long stretches of peace. The war was initially sparked by Philip VI of France’s formal declaration that Edward III’s territories in France (most notably Aquitaine) had been confiscated because the young English king had refused to act as his vassal and to hand over Robert of Artois, Philip’s mortal enemy. The war escalated after the Declaration of Ghent in 1340, when Edward proclaimed himself king of France on the basis that, through his mother, he had a superior claim to the throne than Philip, as she was the daughter of Philip IV, while Philip VI was merely his nephew. France, however, had never allowed for kingship to descend through the female line.
Corrigan’s dramatic description of the Battle of Sluys in 1340 gets the book going. Though fought between opposing navies, Sluys was essentially a land battle that took place on a flotilla of French ships chained across the mouth of an estuary, with the victorious English army moving from vessel to vessel and pushing their French opponents overboard. Corrigan accounts for England’s victory being due to superior tactics and the far greater effectiveness of the longbow in comparison to the French crossbow. This was down to both to the nature of the weaponry and the superior skill of the Anglo-Welsh archers. They proved decisive time and time again at the great set-piece battles of Crecy, Poitiers, Agincourt and Verneuil.
