Just now I was trawling through the roll of the 10H for a possible link in the Pte. Turtle Memorial post, when I spotted the following on p.189 of WO 100/189:
The entry concerns civilian servant Charles Cable who went to SA with a senior officer. It does not say anything about the issue of a Bronze medal; however it does mention Cable's being captured at Sanna's Post. By the way, I could not find a confiriming entry in Palmer.
However, the entry for Charles Cable on my trusty "Cavalry CD" shows Cable as "Civilian servant 10th H' and awarded a Bronze medal. Incidentally Charles Cable is noted as PoW at Sanna's Post - with a query - and "released 5/6/01.
