The early Magindanao records give the impression that the arrival of Kabungsuwan and the conversion of the people of Magindanao to Islam were accomplished peaceably. The word Samal is never mentioned and the Samals are always considered as aliens in every respect. The Samals seem never to have settled in Magindanao itself, but they did settle for some time on the Island of Bongo or Bungud, that lies opposite the mouth of the Pulangi, and at Batwan and Banago, near Malabang. From these places they moved later to Sibugay and Sarangani and the Gulf of Davao. Combés called the Samals Lutaw and said that they were in the employ of Corralat, and manned some of his boats, fighting and carrying on piracy side by side with the people of Magindanao and with the Iranun. Summing up the preceding evidence, we can unhesitatingly say that the Samals came to Magindanao with Kabungsuwan, but that they did not settle on the soil of Magindanao, nor did they intermarry sufficiently to assimilate with the Magindanao people. The character of the conquest Kabungsuwan achieved and the bearing it has on the admixture of races in Mindanao is therefore of special interest. When Kabungsuwan arrived at the mouth of the Pulangi there were on the neighboring soil of Magindanao the following settlements: Slangan, Magindanao proper, Lusud, Matampay, Tagiman, and Katitwan. The first and the last were probably the greatest and the strongest of all, for they were the first to meet Kabungsuwan and interrupted his advance at Tinundan. After some fighting they were evidently defeated and retreated up the river. The people of Magindanao, under the leadership of the brothers Tabunaway and Mamalu, came next, but their attitude was not hostile. For some reason they secured an alliance or agreement with Kabungsuwan and invited him to Magindanao. They submitted to a form of Mohammedan baptism and to circumcision, and towed Kabungsuwan's boat from that place up to Magindanao. Hence the meaning of the word tinundan, the place of towing. The ceremony for circumcision occurred at Katuri, the little settlement on the river just opposite Cotabato; the baptism or washing occurred at Paygwan at the mouth of the river. The word katuri means circumcision.
