During WW1 Lawrence was in the Tyneside Pioneers, and according to Richard Dunning was in the front line 100 yards from Lochnagar when it was blown up. Given that the (unannounced) 27 ton explosion was heard and felt in Kew, it must have unnerved him considerably - fortunately the Pioneers were the only troops, out of 100,000, who didn’t go over the top on that day. Lawrences masterpiece, The Altruists, (first exhibited at British Empire Exhibition, Wembley, 1924, then British Pavilion, 1925 Paris and now lost) showing First World War soldiers and a selection of robed figures grouped on either side of a risen Christ, was his most ambitious serious attempt to sublimate his traumatic WW1 experiences.
