Battle of Andranosampona

The Battle of Andranosampona was the main pitched engagement of the final conquest of Madagascar. After a successful landing on the east coast, General Duchesne's column advanced toward Tananarive. At Andranosampona, French troops encountered the main Merina army, strongly entrenched on the heights. After a frontal assault and several encirclement maneuvers, the French broke enemy defenses, opening the road to the capital.

The French protectorate imposed in 1885 was never accepted by the Merina court, which mobilized its army upon announcement of the 1895 expedition. The campaign was marked by disease (malaria) and extreme logistical difficulties. Andranosampona was the lock of the island's center, defended by most royalist forces.

Duchesne employed artillery to neutralize Merina entrenchments, then ordered a line attack with flanks protected by tirailleurs. Merina resisted through several frontal charges and skirmishes, but French discipline and concentrated fire opened a breach. The royal army withdrew toward Tananarive.

The victory at Andranosampona decided the fate of the campaign. A few weeks later, Duchesne's column entered Tananarive without major resistance. Queen Ranavalona III abdicated in October 1895. Madagascar became a full French colony; resistance continued sporadically until 1897.
