A letter from the Foreign Office of the Kingdom of the Netherlands to the Oranje-Vrijstaat and Zuid-Afrikaansche Republiek, transcripted and published in Dutch newspapers,
On the day of the 8th of January, 1806, the armies of the British Empire conquered Capetown. Taking advantage of the Netherlands' occupation by French imperial forces and their collaborators, the colony-hungry British would go on to establish themselves as the pre-eminent power throughout South Africa over the course of the Napoleonic Wars. In 1814, on the day of August 13th, the British forced a convention upon the Netherlands that saw to the permanent Dutch removal from the Cape, and international recognition of Britain's capture of South Africa. As would continue to happen over the course of the war, the British took advantage of a war-addled and French occupied Netherlands to see to the carving of the Dutch colonial empire. It was a deception that had long lasting and devastating consequences, as no doubt yourselves the Boers, more so than anyone else, know best.
With British possession of South Africa came the arrival of British settlers—not only from England, but from Britain's colonies abroad, India included. The hard fought and bountifully rich Boer homeland, the pearl of the African continent, became tainted. Defiled. The British conquerors subjected the Boers to the empty countrysides, stealing away the cities and the coasts. The Boers, resilient and fiercely independent peoples, made the most of their subjugation. They took the opportunity of having been evicted from their homeland to find themselves yet another patch of the uncivilized and unsettled lands of Africa to make their own. The Great Trek instituted yet another wave of technological innovation and proud European ingenuity to the African countryside. When the British stole the Boer's homes, the Boers built themselves new ones, larger, finer, and on better land. The penalty imposed upon the Dutch settlers of Africa was undone through their own effort, with no assistance from their new British overlords, and indeed, with the utmost contempt. Even now, it is no doubt that the war-hungry Edward looks upon the Boer Republics east of the Cape with the same malicious intent that his forefathers looked upon the Cape itself in the days of Napoleon. The British seek to make all of the south of the African continent their domain, to fill it with their settlers, to impose their values and their language, and to once again sweep the Dutch-blooded of Africa out of their hard-earned homeland. The British call us, our people, "dogs". To them, we are mutts to be swept out of the way to make room for their own ambitions. I invite the Boer Republics to prove Albert Edward, the equally war-hungry and equally insane heir of Victoria, right. To show him that the Dutch people, our people, are dogs—and that if you kick a dog too hard, if you deny those of Dutch blood their homeland in all unity, the dog bites.
The British garrisons mobilize in Europe. They seek to clean the European continent of all of the evils that they witness plaguing it; evils like nationalism, like pride, and the unity of all peoples in their rightful homeland. Just as the British not so long ago took advantage of war in Europe to enforce their designs abroad, the people of the Kingdom of the Netherlands ask their Boer brothers in southern Africa to take advantage of the war-addled British tying their hands in Europe, and to smite the Union Jack off of the face of the Cape. Resist the Britons, show them the might of Dutch blood. Make war now, while your enemy has their eyes closed to Africa, and you will be making peace for yourselves in the decades to come.
The policy of the Kingdom of the Netherlands is the pride and unity of the Dutch people, wherever in the world they reside. We do not forget our stolen cousins in Africa, and unlike the British, we do not seek to impress any amount of oppression upon them. The independence of the Boer Republics and the people for which those republics stand will be guaranteed by their involvement in this war, and by their defeat of Britain.
Whoever has Dutch blood flowing in their veins, free of foreign blemishes; whose heart glows for their country, rejoice in song as we do!
