The best books to understand the Hundred Years' War

Quite simply the seminal work on the war. It describes the twists and turns of politics and diplomacy in fascinating detail. Not a read on the train but a magisterial study and an essential work for those interested in the subject.

"The Fair" Phillip IV of France died in 1314. His three sons ruled after him in turn, and none provided a legitimate heir, so when the youngest son, Charles IV, died in 1328, the Capetian dynasty, which had ruled France for over 300 years, came to an end. 

But Phillip IV had a daughter, Isabella, who had married Edward II of England, and so their son, the future Edward III, was the nearest male relative to the deceased Charles IV.

Isabella was adamant that her son was the legitimate heir to the French throne, and it was this claim that was pursued throughout the Hundred Years War and which was only relinquished in 1802.

Isabella has not had good press. Derided as "the she-wolf of France," she was an adulteress, waged war against her husband, and was probably complicit in his murder. In fairness, she had much to contend with. Edward II was a weak and vicious ruler, a homosexual who lavished more attention on his catamites than on his wife. This book is an excellent biography of a woman whose impact on history was dramatic and far-reaching.  

There are lots of books about Crecy, the first major land battle of the war, but here the authors examine and compare all the original sources. 

Medieval historians were not necessarily interested in the things that modern historians are, so there are many gaps in the various accounts. Similarly, many academics, through no fault of their own, do not understand the mechanics of organising, deploying, and administering an army, or how it actually fought. 

Here the authors do examine points such as what formation the English armies would have taken up, where exactly the archers would have been placed, and suchlike. 

While I, with my own military experience, might not agree with all the Authors’ conclusions, they do an admirable job of comparing, contrasting, and shining light into dark corners.

Thomas of Walsingham was a monk in the abbey of St Albans, then the equivalent of the National Archives where all official documents were deposited about the war. 

Based on the reports, letters, charters, and reports of parliamentary debates that Thomas was able to access, he wrote a history from 1376 until the year that he died, 1422, so the work is an account of the war as it appeared to an educated contemporary. 

Henry of Monmouth, Henry V, was the second king of the disputed Lancastrian dynasty, and in my opinion the greatest Englishman who ever lived.

He was king at 25, slaughterer of the nobility of France at 27, regent and acknowledged heir to the French throne at 32, and dead at 34. Had he lived, the history of Europe might be very different. He was a man who shaped English history and who still affects Anglo-French relations to this day.

This book, by Ian Mortimer, one of the very best authors of the period, looks at the year 1415, the year when the young Henry led a sick, exhausted, and starving English army to a stunning victory over a far larger French force at Agincourt, in an example of leadership and military professionalism of the highest order.
