 By March 1906 the other kingdoms had all fallen, leaving Tiku as the last Torajan lord. The Dutch took Rantepao without a struggle, unaware that the city's surrender had been arranged by Tiku. Through a letter, the Dutch commander Captain Kilian told Tiku to surrender, a demand Tiku was unwilling to entertain. Aware of Tiku's gathered forces and numerous fortresses, Kilian did not attempt a direct attack. Instead, in April 1906 he sent an expeditionary party to Tondon. Although the party's approach was not resisted, after nightfall Tiku's troops attacked the Dutch camp in Tondon; this forced the Dutch forces to retreat to Rantepao with Tiku's men in pursuit, suffering numerous casualties along the way.
