After the kingdom's defeat, the king and his advisors were taken to [[Kagoshima]], where they were forced to sign a number of oaths, swearing their loyalty and fealty to Satsuma. Among these were agreement to Satsuma's version of history, in which Ryûkyû had been beholden to Satsuma since the very beginning of the 13th century, and was deficient in its fulfillment of its obligations to Satsuma, thus bringing this invasion, colored by Satsuma as a punitive mission, upon itself; the advisors were also required to swear their loyalty to Satsuma over loyalty to their own king, agreeing to turn against the king under certain circumstances. Only Tei Dô refused to sign. As a result, Satsuma samurai beheaded him on the spot.
