Elmarie, thanks for the clarification – the photo would suggest the site of the engagement was some way in the distance on the photo posted by EFV.
Just trying to identify the 15 British wounded. The three officers were all Lieutenants in the IY and were baptised Francis Arthur Montague Rawes, Ernest William Thain & William Halfenden Selfe Leonard. The last two were in the 3rd (Gloucestershire) Company of the 1st Battalion IY. Rawes originally enlisted in February 1901 as a Trooper in the 27th (Devonshire) Company, 7th Battalion IY and was commissioned later in the year to the 1st Battalion IY where, according to Medal Rolls, he served on the Battalion Staff.
Rawes had a rather remarkable life:
Born in 1882 in Cornwall and raised in Devon. Attended Sherborne School. After the ABW he returned to England in June 1902 on the Orcana. In 1906 he returned to South Africa and married in Pretoria the following year. Then back to England where he tried his hand at poultry farming in Cambridgeshire. In early 1914 he sold the farm and went to Ceylon (Sri Lanka) where he tried his hand as a Tea Planter. In 1915 he returned to England and enlisted and served in France as a pilot in 53 Squadron, Royal Flying Corps. By the end of the Great War he was stationed at Polegate Airship Station in Sussex piloting airships.
He divorced in 1919 and remarried 3 years later. Not sure what he did for the next period but in WW2 he served at home in the RAF and ended the war commanding No 2 Motor Transport Company as shown in the photo below, where he is centre of the front row. He died in Chichester, Sussex in 1960.
His biographer on Ancestry is aware he was wounded at Moolman’s Spruit and has attached the photo of the 2001 Plaque to his profile.
Finally I can confirm, despite their lack of mention in any of the three accounts in the SAMHS article, that the MIC of the 1st Worcesters were definitely involved on 20 April 1902 and their man who was wounded was 2933 Private George Payne, who was born in the Black Country in Staffordshire.
