Helena saw relatively little of her surviving siblings, and continued her role as a support to the monarchy and a campaigner for the many charities she represented. She and Christian led a quiet life, but did carry out a few royal engagements. On one such occasion, the elderly couple represented the King at the silver wedding anniversary, in 1906, of Kaiser Wilhelm II (Helena's nephew) and his wife Augusta Victoria (Christian's niece). During the Edwardian period, Helena visited the grave of her son, Prince Christian Victor, who died in 1900 following a bout with malaria while serving in the Second Boer War. She was met by South African Prime Minister Louis Botha, but Jan Smuts refused to meet her, partly because he was bitter that South Africa had lost the war and partly because his son had died in a British concentration camp.
