An expeditionary corps was sent under General Jacques Duchesne. First, the harbor of Toamasina on the east coast, and Mahajanga on the west coast, were bombarded and occupied in December 1894 and January 1895 respectively. Some troops were landed, but the main expeditionary force, however, arrived in May 1895, numbering about 15,000 men, supported by around 6,000 carriers. The campaign was to take place during the rainy season, with disastrous consequences for the French expeditionary corps. As soon as the French landed, revolts erupted here and there against the Merina government of Queen Ranavalona III. The uprisings were variously against the government, slave labour, Christianisation. As the French force advanced towards Antananarivo, they had to build a road along the way. By August 1895, the French were only mid-way at Andriba where there were numerous Malagasy fortifications but only limited fighting. Disease, especially malaria, but also dysentery and typhoid fever, was taking a heavy toll on the French expeditionary corps. The expedition was a medical disaster: about 1/3 of the force died of disease. Altogether, there were 6,000 deaths in the expedition, four-fifths of them French. The Malagasy Prime Minister and Commander-in-Chief Rainilaiarivony tried to resist at Tsarasaotra on the 29 June 1895, and at Andriba on the 22 August 1895. He again attacked the Duchesne "flying column" in September, but his elite gunner troops were decimated by the French. Duchesne had to send a "flying column" from Andriba on the 14 September 1895, formed of Algerian and African soldiers as well as marines and accompanied by pack mules, to the capital. They arrived at the end of September. An artillery battery was trained on the royal palace from the heights around the capital, and high-explosive shells were fired on the palace, killing many. The Queen promptly surrendered. In the whole conflict, there were only a few skirmishes, and only 25 French soldiers died from fighting. On 1 October 1895, the Merina Kingdom signed a treaty with France wherein it became a French protectorate.
Aftermath
The conquest of the island was formalized by the 6 August 1896 vote at the French National Assembly, which resulted in favor of the annexation of Madagascar. Despite the success of the expedition, the quelling of the sporadic rebellions would take another eight years until 1905, when the island was completely pacified by the French under Joseph Gallieni. During that time, insurrections against the Malagasy Christians of the island, missionaries and foreigners were particularly terrible. Queen Ranavalona III was deposed in January 1897 and was exiled to Algiers in Algeria, where she died in 1917.
