robert was posthumously awarded the victoria cross for his courage on 6th january 1900 when at the siege of ladysmith the british were taken by surprise at waggon hill, just as the three foremost boers reached the summit of the hill, which would almost certainly have meant that ladysmith would have fallen, robert and another man, trooper albrecht of the imperial light horse, shot them and retook the hill. sadly just afterwards, as robert was helping soldiers into their firing positions, he was shot in the throat and died.
