   Pte. David Burns Gillies, K.L.R., eldest son of the late Mr. David Gillies and of Mrs. Catherine Gillies, of 295, Knowsley-road, Bootle, was killed in action on August 6th, when serving with the M.G.C., to which he was attached after joining the Army. A native of Bootle, he was educated at Christ Church school and the Liverpool Institute, and subsequently became book-keeper for the firm of Messrs. Michael Manion, Water-street, Liverpool. He was born on January 25th thirty-two years ago, and joined the Army this year on the anniversary of his birth. Deep sympathy will be felt with his young widow, who resides at Mossfield-road, Orrell Park, and with the mother and family. 
   A comrade writing to the relative, says. "He was killed by a shell exploding early on the morning of August 6th while at the post of duty. I happened to be quite near him at the time, and went to him at once, only to find that death had been instantaneous. He was to me not only a companion, but a true and close friend. My heart aches for his wife, of whom your son had spoken to me do often . . . . . Some while ago we agreed to write home for each other should the necessity arise.
