A Blue Devil of France: Epic figures and stories of the Great War, 1914-1918
CHAPTER FIVE
EPARGES AND CALONNE TRENCH
_This period of the author's life begins during the first days of October, 1915, and ends on the eve of the battle of Verdun, February 20, 1916._
_He directed certain works in the different sectors of the Verdun front, at Eparges, at Calonne Trench, in the Hauts-de-Meuse, at Chevaliers Wood, at Ornes, at Forges and Béthincourt, at Corbeaux Wood, etc._
_He remained a greater part of the time at Eparges, which was then the bloodiest sector on the front. The episodes in mining warfare left an impression of horror with those who were lucky enough to survive._
