The duty of tracing missing military personal is the responsibility of the War Office. Full details of the Army organisation by which this function is performed are contained in the answer given to my hon. Friend on 19th December last. A panel of voluntary workers organised by the War Organisation of the British Red Cross Society carries out inquiries among patients in military hospitals in this country with a view to collecting information about missing men with whom the patients may have been in contact in the field. This work, for which we are most grateful, is done at the request of the War Office, to whom reports are rendered.
