Found this in a copy of Mainwaring’s obituary. He was heavily involved in the burials on the western slopes of Isandlwana and he may hold the key to a number of critical questions regarding the late stage of the battle. From this, it sounds like a detailed narrative and a collection of maps was privately printed with a copy presented to the Natal Administration. Any ideas how to pursue this lead? I contacted the Royal Geographical Society without luck.
“His recollections of these events were privately printed at Cairo in 1895 and re-edited last year after he had revisited the old battlefields forty-two years after the events described. A copy of this narrative was presented by him to the Natal Administration together with copies of his beautifully executed maps and sketches.”
