The Battalion remained in bivouacs and was employed in finding working parties in connection with preparing for the attack on GUEDECOURT. The casualties were all caused by shell fire, the work consisting of digging trenches and repairing roads and much of this was necessarily carried out under shell fire.

Coalville Times article - Friday October 27th, 1916

Official news has been received that Private P. Tookey, of the Leicestershire Regiment, a former Coalville man, was killed in action on the 19th September. Writing to Mrs Tookey, his mother, who lives in Hermitage Road, an officer states, “I expect that by now you will have heard of the death of your son, who was killed in action on the night of September 19th. I might say that I have lost one of my best machine-gunners and he will be greatly missed by all his friends. He was killed instantaneously by a shell and could not have suffered. Any further information that I can give you if you will write to me, I will try and assist you.”
