Second Boer War
The President of the South African Republic, issued an ultimatum
South Africa
Paul Kruger, the President of the South African Republic, issued an ultimatum on 9 October 1899, giving the British government 48 hours to withdraw all their troops from the borders of both the Transvaal and the Orange Free State, albeit Kruger had ordered Commandos to the Natal border in early September and Britain only had troops in garrison towns far from the border, failing which the Transvaal, allied to the Orange Free State, would declare war on the British government.
