I found this topic pertaining to I S TerBlanche. He was my Grandfather on my maternal side and I am in possession of a 13 page typed manuscript documented by G J Visser during the war sketching the movements of I S TerBlanche during the war. Should this be of interest to anyone, I will make a copy available. The document is titled "DIE OORLOGSERVARINGS VAN MNR. I. S. TERBLANCHE GEDUURENDE DIE ANGLO-BOEREOORLOG SOOS OPGETEKEN DEUR J. G. VISSER.
