Very gallant conduct on 14th September in saving horses which had become entangled in blocked road, and man-handling guns away from a position which had become untenable from a very heavy shell fire, continuing to work, although wounded.[4][5]
During the Second World War Schreiber served with the British Expeditionary Force (BEF) in France between 1939 and 1940.[7] Promoted to acting Major-General on 26 April 1940,[8] he became General Officer Commanding (GOC) 61st Infantry Division on the same date, before being made GOC 45th Infantry Division later in 1940. In May 1941 he was promoted to acting Lieutenant-General[9] to take command of V Corps later that year. In May 1942 he received the rank of temporary lieutenant-general,[10] and in July that year he was appointed to command the British First Army (in reality an Anglo-American formation) which was later to be the parent organisation for Allied forces in French North Africa after Operation Torch in November. Schreiber had to resign after only two months, however, as he developed a kidney problem and became unfit for active service.[11]
