The criticism of the British Concentration Camps, and they being referred to as ‘Death Camps’ started in the European Press while the Boer War was still ongoing. Since the Strategy was to clear the Veldt of the entire Boer population, with complete indifference to the fate of the Boer civilians in their custody, it would be very difficult for it in modern terms to avoid being classed as genocidal.
IMHO the politicians never thought in genocidal terms, or rather they were well aware that if they ever did anything that was DIRECTLY genocidal there would be hell to pay at home, so avoided doing it
But often those on the ground had different ways of looking at things. Take the removal of the Tasmanian aboriginal people for instance - the British politicians thought of it as moving them to a reservation, opening the land up for settlement and removing the danger of constant low-level conflict. The people involved in doing it by and large thought of it as a grouse shoot or a herding operation, tho it failed spectacularly and they needed an evangelical madman to tempt the natives out with promises that proved to be lies, and they all ended up dying of misery, alcoholism etc. It LOOKS LIKE genocide, and tastes like genocide, but it wasn't how it was perceived by those who had the political responsibility, and it wasn't an immediate genocide, since the remains of the aborigines carried on living, just more of a living death until there were none left
