The battle of Crécy in 1346 is one of the most famous and widely studied military engagements in history.

In this new study, Michael Livingston reveals how modern scholars have used archived manuscripts, satellite technologies and traditional fieldwork to help unlock what was arguably the battle's greatest secret: the location of the now quiet fields where so many thousands died.
