East Africa's military operations in western and southern Madagascar Island went very smoothly. At this time, the British Government had no desire to stir up another hornet's nest, as it was under severe threat from the French.
During the South African War, France had taken advantage of Britain's inability to attend to the Kingdom of Imerina and occupied considerable territory, expanding its colonies into the highlands of the Kingdom of Imerina.
Therefore, in order to focus more fully on the French threat, the British Government's only option was to stabilize East Africa and prevent it from taking sides in the struggle between Britain and France.
To be honest, given East Africa's forces on Madagascar Island, it had no need to take sides at all and could even directly alter the island's balance of power. However, as Britain and France were the leaders of the current world order, East Africa had no need to fall out with both nations over a Kingdom of Imerina.
France was equally nervous about East Africa's military activities on Madagascar Island. However, the Kingdom of Imerina had always leaned toward Britain, and before France had completely colonized it, there was no need for France to enter into talks with East Africa. It could only watch helplessly as East Africans occupied western and southern Madagascar Island.
Yet this also made the Kingdom of Imerina more important in the eyes of Britain and France. As East Africa expanded, there were fewer and fewer places in Southern Africa where Britain and France could get their hands in. Britain at least had the Cape Colony as support, while France now had only French Réunion Island in the southern Indian Ocean region fully under its control.
The contest between Britain and France over the Kingdom of Imerina would only grow fiercer.
