 A dispute broke out when the king apparently reneged on an agreement to send his son Drian-Ramaka to Goa for Catholic education; the sailors seized the boy by force and their ship was briefly attacked before sailing to Goa.In April 1616 the Jesuits returned to Anosy to exchange Drian-Ramaka for Chambanga's other sons, which the king refused; following accusations, and realizing their missionary work was in jeopardy, the Jesuits settled for a distant relation of the king.Chambanga became further distrustful when the Portuguese began prospecting for gold and silver; he suspended trade, attempting to starve them out of Anosy.
