 The authors of the 1915 report explain that ‘‘If it be not permissible to compel a man to fire on his fellow citizens, neither can he be forced to protect the enemy and to serve as a living screen’’.After World War II, it was claimed by German SS general Gottlob Berger that there was a plan, proposed by the Luftwaffe and approved by Adolf Hitler, to set up special POW camps for captured airmen of the Royal Air Force and the United States Army Air Forces in large German cities, to act as human shields against their bombing raids.Berger realized that this would contravene the 1929 Geneva Convention and argued that there was not enough barbed wire—as a result, this plan was not implemented.
