This group belonged to an officer in the British Army working in the Sudan and Eritrean theatre against the Italians. Interestingly enough his rank on the MBE recommendation is given as “Bimbashi” (from Turkish: Binbaşı, “chief of a thousand”) which is a major in the Turkish army, the term originated in the Ottoman army. The title was also used for a major in the Khedivial Egyptian army as Bimbashi (1805–1953). It was also used by the Serbian revolutionaries as Bimbaša (Serbian Cyrillic: Бимбаша) in 1804-1817. So I am guessing the equivalent was Major Andrew Cameron Robertson of the Sudan Defence Force.
The recommendation reads “This officer has rendered meritorious service during the last six months having been in entire charge of the M.T. Stores (American type) of all the Imperial forces in the field (Sudan command). With no other officer to assist him and with only a mixed Sudanese and Indian Staff he has earned for his work in this sphere the personal thanks of both Divisional commanders and his services have been of a high order and great value. He was responsible for the uncasing and preparation and equipping and testing and issue of all new and repaired American type vehicles, and the supply of tyres, parts and accessories for their maintenance by units and advanced repair workshops in the field – British and Indian armies, S.D.F. K.A.R. W.A.F. S.African, Free French and Belgian, Ethiopian Patriot forces included.”. It is signed by William Platt, Lieutenant General commanding troops in the Sudan and Eritrea, 14th August 1941.
The group consists of the Military MBE, the 1939-1945 Star, the North Africa Star, the Defence Medal and the 1939-1945 War medal with the device for Mentioned in Dispatches. The MBE was gazetted on the 30th of December 1941.
Robertson was granted as an emergency commission to 2/Lieut on 12th June 1940, having already been commissioned in the Khedive’s Army. This was gazetted on 5th January 1943. His service number was 254419.
