Steve,
Army Order 5 of 1901 (

) sets out the parameters for the issue of the War Gratuity which includes Colonial troops and provision for those who had died on service.
The Proceedings on Discharge that enclose some South Africa units' attestation papers contains a section on the front page with instructions to the Paymaster. These often contain settlement sums of money, eg
I had always imagined this was the settlement of outstanding pay. From you post, I started thinking whether this could have been use to pay the War Gratuity for non-fatal casualties but I think not because there are some men (mostly not casualties) with no settlement values.
Given the difficulty of sending medals and clasps to ex-South African servicemen in the years after the war, I wonder just how many received a War Gratuity?
