I have in my collection an Anglo-Boere Oorlog medal to a Sergant-Major Freidrich Traugott Mauchle of the Transvaal Staatsatillerie. Mauchle was one the few professional soldiers in the Transvaal and was most likely German or Swiss. He fought on the Natal Front from October 1899 and later in the Transvaal.
In the National Archives London amongst the papers in CO 417 - Colonial Office: High Commission for South Africa, Original Correspondence there is printed document Translations of Boer Documents by the Director of Military Intelligence, South Africa. Item 9 is the Translation of Diary of Sergeant-Major Mauchle of State Artillery, the diary is identified as Diary No. 3 pieces 1 and 2 are noted as missing. Mauchle was taken prisoner at Zusterhoek, Transvaal on 26 October, 1901. No doubt this was where the British got his diary which covers the period 15 July to 24 October, 1901. I have long wondered what happened to Diaries 1 and 2.
Reading around on a different topic I was surprised to find a direct account of Mauchle's capture with some amusing detail. In Jim Wallace's account of the Canadian Scouts Knowing No Fear he relates that Mauchle was captured by the Canadian Scouts. When Mauchle arrived at the PoW camp in Pretoria he wrote to the camp commander complaining that he and his comrades had been robbed of their money and his diary had been taken. Mauchle maintained that a major of the Canadian Scouts took their names and amounts of money taken promising the money would be returned when they reached the PoW camp. The camp commander passed the details onto the Provost Marshall who wrote to Major CJ Ross, Canadian Scouts. Major Ross replied he would have forwarded the money "had he known the whereabouts of these men". It would be interesting to know if the Canadian Scouts had taken all three of Mauchle's diaries and parts 1 and 2 somehow got lost in transit to Military Intelligence. In January 1902 Mauchle was sent to Deadwood Camp on St Helena, it is not known when he returned to South Africa.
After the war Mauchle went to work at the Daspoort Bacteriological Institute and Laboratory in charge of the library and stock records. The Institute was led by Arnold Theiler (from Switzerland) who pre-war served as a Transvaal government veterinary surgeon. In 1898 Theiler set up the Daspoort Institute. During the war Theiler served as veterinary surgeon to the Staatsartillerie and perhaps where he first met Mauchle. In 1901 the British allowed Theiler to continue his important research at Daspoort.
Mauchle married Mathilde Henriette (nee Stohr) who died in 1925.
Nothing more is known of Mauchle.
