A large group of Russian and French POW\u27s (including a Senegalese prisoner on the ground in the front row) pose for a photograph in the prison compound at Langensalza. Note the POW identification badges on the left arms of the prisoners. The Germans integrated prisoners from various Allied nations into the same prison camp to avoid accusations of favoritism. The Western Entente governments protested against this policy because of the risk of epidemics from Russian troops. The Germans also used photographs of various Allied troops for propaganda purposes to bolster the war effort.https://scholarworks.wmich.edu/wwi_pow_camps/2212/thumbnail.jp
