What do I do... to find out about, or write to, prisoners of war? If I am uncertain whether my relative or friend is a prisoner, I write for information to the Regimental Office of his unit in the case of Other Ranks, or to R. Casualties Branch, War Office, London in the case of Officers. If I want to write letters or send parcels to a prisoner, I ask at any main Post Office for Leaflet T2280E, which will give me full details of how to go about it. I do not use the telephone for enquiry in either case.
