Heavy shelling on our left + Right at 4:30 PM. We send over some trench Mortars, the Huns retaliate + send showers of all sorts. Am 20 feet away when they burst they seem to lift up the place where I am in + shake it. Am outside bombers quarters, the objective of the Huns. The concussion is awful + creates headache. A large lump of debris hits me in back. At about 7 PM Private J. Kelly is killed & the following injured by explosion of bomb accidentally. Private O’Keefe (working party) MacCormick, [Poppy?] + Hanlin.
