Biography: (From a variety of internet based sources)
Alexander von Stosch was killed in a fatal accident near Namur on 27 February 1918 while Vorstand of Kraftfahrstelle Namur, uniform of an Oberleutnant in 5. GRzF. His obituary in the Heldengedenkmappe states he was a participant of the war in Boer War and subsequently served in the Argentine army before returning to Germany through the blockade in 1915 by using false papers.
A check of the relevant Gotha shows that Alexander Wilhelm Leopold v. Stosch was a Leutnant der Reserve außer Dienst (retired) in 1913. He was born on 23 February 1874 at Schwerin. Alexander v. Stosch had been originally commissioned into the 2. GRzF on 18.8.95 and transferred to Garde-Grenadier-Regiment Nr. 5 on 1.4.97. He left the Army on 18.8.97, returning to service as a reserve officer in Ulanen-Regiment Nr. 12 on 12.9.02. He retired from reserve service on 18.5.05 with a view to emigrating. I then find him on promotion to Oberleutnant der Reserve a.D. on 26 November 1915 on the staff of the commander of motorized troops of 11th Army.
I do not find him on any of the award rolls that have been transcribed, though presumably he'd picked up an ÖM3K from Austria-Hungary during his Balkan’s service. Or to whatever style prevailed in Argentina, where he was an officer from circa 1905 to 1914?
Before WW1 the only medal he had was the Kaiser Wilhelm I Centenary Medal, earned for being on active duty on 22 March 1897.
I'm sure he got the ‘usual’ Iron Crosses 2nd and 1st Class during the Great War, and as a General Headquarters staff type, I'm fairly sure he would have had the Austro-Hungarian Military Merit Cross 3rd Class with War Decoration, since he was on von Mackensen's staff. Quite possibly something from Bulgaria as well, or even Turkey.
A lot of this information was provided by a couple of researchers on the GMIC who helped me in the same way as we try to help others.

David
