Kipling was plunged into acute, life-long grief when John was posted missing at the battle of Loos. Through eminent friends, he had fiddled his son a commission after the schoolboy was initially rejected for poor eyesight.
Unusually for a man now officially classified as one of the 600,000 identified British dead in the first world war, John Kipling has two memorials. One is the newly named cemetery headstone.
