Prisoner Of War Fiction and Poetry

A work-based request for information here, on the off-chance that anybody with the right know-how is reading. Could anyone furnish me with information about any fiction or poetry published in England up to and including early 1948 that deals specifically with the experience of the POW camps? It doesn't need to have been written by someone with insider knowledge- in fact, it would probably be more helpful if the literature was imaginative rather than experiential. It would also be interesting to know if British, American, Canadian or Australian novelists were writing about the camps on their own soil in this period.

Thanks,

J
