The letter is the elementary form of war literature. Jean Norton Cru regretted that there were so few correspondences among the three hundred books listed in his Witnesses (1929). Two scenes are omnipresent: the distribution of letters and their dispersal among the corpses on the battlefield.
Mail delivery. At the front, the mailman is a formidable and feared figure. Barbusse also likens him to a storyteller, a sort of rhapsode or itinerant reciter who serves as a conduit between the front and the staging area, bringing news from the cantonments and headquarters. The ritual of distribution is a crucial part of the day. Letters are kept, reread and sent back, to prevent them from being forgotten, because soldiers are, as Barbusse puts it, "machines for forgetting".
The scattering of letters around corpses on the battlefield. Letters from slain enemies are part of the spoils of war, along with identity papers and photographs, when the pockets of the dead are searched. Barbusse, with his documentary mania, sends German letters to his wife, translating them. The same sort of scene can be found in Genevoix or Montherlant, who despises the letter because it deviralises the warrior by tying him to the rear and to women. For them, the letters that flutter about after the battle are like the souls of the dead that escape. Mention of the letters that continue to arrive for those killed is also an obligatory tableau, in Dorgelès and Barbusse in particular. The leitmotif of the suffering letters is death.
A final aspect of letters is the exchange in which they participate. Norton Cru considered them to be the most faithful testimonies of the war to the newspaper, the literary concern being absent, or at least less so than in other genres. Yet we know that the addressee is always partly the author of the letter. After a disastrous assault, Dorgelès wrote very different accounts of the event to his mother and his mistress on the same date, seeking to appease the former and worry the latter, and doubtless lying to both, to one by discretion or ellipsis and to the other by exaggeration or hyperbole. We could quote Norton Cru's own letters to his sisters, brothers and mother, in which we find very different versions of each event.
