Kandumbo Stones

Twenty-five kilometers from Huambo, heading toward Bié, rises a colossal granite massif that served as the stage for titanic battles waged by Soba N'Dala against Portuguese colonizers; this formation is the magnificent natural stronghold known as the Pedras do Kandumbo.
The Huambo people, having previously suffered defeats at the Embala do Huambo (near Soque) and later at Pedras da Ganda and Kané (near Kaála), pinned all their remaining hopes on this natural fortress, on the great chief N'Dala (known as "The Viper"), and on his war commanders: Kalley, Kassango, Tchipulowando, and Tchinlundulo.

The year was 1902, and white colonizers, aided by a Boer force, laid siege to the Kandumbo Fort; The battle lasted three days and four nights of ceaseless gunfire, at the end of which-on September 20, 1902-Captain Teixeira Moutinho of the colonial army ordered the final shots to be fired from two 70mm cannons against the people.
The Portuguese Army-aided by the Boers, their cannons, and the treachery of a Soba who showed the besiegers how to penetrate the Natural Fort—won the Battle of Kandumbo.
N'Dala lay dead near the outer palisade.

N'Dala was succeeded by Nondolo, Kachikwala, Xilundulo, Sambuanda, and Samokoloco.
The skulls of N'Dala and his successors, with the exception of Sambuanda and Samokoloco, rested in a triangular reliquary known as a Kalunda.
The huts of N'Dala and the Tchimbanda Samakaka were rebuilt, along with the small Etambo temple and some of the huts belonging to the warriors and their wives.
