But Rhodes's final and most unhappy venture was the attempt to force, by violent means, a solution of the Transvaal problem. He hoped that the Uitlanders might be able, by a revolution, to overthrow Kruger's government, and, perhaps in conjunction with the more moderate Boers, to set up a system of equal treatment which would make co-operation with the other British colonies easy, and possibly bring about a federation of the whole group of South African States. He was too impatient to let the situation mature quietly. He forced the issue by encouraging the foolish Jameson Raid of 1895. This, like all wilful resorts to violence, only made things worse. It alienated and angered the more moderate Boers in the Transvaal, who were not without sympathy with the Uitlanders. It aroused the indignation of the Cape Colony Boers, and embittered racial feeling there. It put the British cause in the wrong in the eyes of the whole world, and made the Boers appear as a gallant little people struggling in the folds of a merciless python-empire. It increased immensely the difficulty of the British government in negotiating with the Transvaal for better treatment of the Uitlanders. It stiffened the backs of Kruger and his party. The German Kaiser telegraphed his congratulations on the defeat of the Raid 'without the aid of friendly powers,' and the implication that this aid would be forthcoming in case of necessity led the Boers to believe that they could count on German help in a struggle with Britain. So every concession to the Uitlanders was obstinately refused; and after three years more of fruitless negotiation, during which German munitions were pouring into the Transvaal, the South African War began. It may be that the war could have been avoided by the exercise of patience. It may be that the imperialist spirit, which was very strong in Britain at that period, led to the adoption of a needlessly high-handed tone. But it was neither greed nor tyranny on Britain's part which brought about the conflict, but simply the demand for equal rights.
