How can I possibly come up with anything new after everything I’ve read on the subject? Letters from soldiers, diaries, war memoirs. I write fiction, and what happened here 111 years ago is far beyond my imagination.

Amélie Lucas-Gary
At the Harazée National Cemetery, among the thousands of soldiers who died in the Argonne forests between 1914 and 1918, something doesn’t add up. While delving into the archives to write this audio drama, Amélie Lucas-Gary uncovered an anomaly in the records that had seemingly gone unnoticed until then.
 
“A Major Mistake” is a geolocated audio drama meant to be experienced while walking along the paths that run alongside the Bois de la Gruerie and the Harazée National Cemetery. Two voices intersect there, separated by more than a century: that of a soldier who died in the Argonne in the fall of 1914, and that of a contemporary author who seeks to understand but is confronted with the impossibility of telling the story.
 
The main soundwalk takes place within the grounds of the Harazée National Cemetery; additional episodes are also available in the town of Vienne-le-Château.
