THE CORPSE AND THE HAVERSACK SIR,—In his article Strix has

not mentioned an important point which has escaped the notice of those misguided people who have tried to ban the novel. Operation Heartbreak and the film The Man Who Never Was. If a ruse has the effect of causing the enemy to make fresh strategical or tactical dispositions, it must be described in official histories, unless they are deliberately falsified. If our historians, acting under official orders, invent reasons for movements of troops or ships because it was discovered later that they were made on false information planted by the enemy, historians in other countries will not be so venal. The late Lord Norwich was surely right when he said that it was a duty to publish ruses so that no one would try them in the next war but, instead, think out something new.—Yours faithfully,
