Capricorn Trench, the night of 20th / 21st August 1917
From G. K. Rose, The Story of the 2/4th Oxfordshire and Buckinghamshire Light Infantry.
“During the night of August 20/21 the Battalion relieved a portion of the front eastward of Wieltje. Three companies were placed in trenches bearing the name of ‘Capricorn,’ but B was further back. During the night a serious misfortune befell the latter. Three 5.9s fell actually in the trench and caused thirty-five casualties, including all the sergeants of the company. On the eve of an attack such an occurrence was calculated to affect the morale of any troops. That the company afterwards did well was specially creditable in view of this demoralising prelude.”
