King Ncapai had many wives. First wife Makhohlisa gave birth to King Diko and Sogoni. His second wife, Indlu yekunenbore, him Makaula and Dabula, while his third wife Iqadi lendlu enkulu, produced Dabula and Mpongoma. Ncapayi is said to have been a fearless freebooter, and a diplomat of note who showed more intelligence than his father Madzikane. According to Rev. Soga, during the year that Madzikane was killed, Ncapayi entered Thembuland to avenge the death. The Thembus under King Ngubengcuka made an ineffectual stand and the Bhacas swept away a large number of cattle. Before Madzikane died and because of his relationship with King Faku, he advised his son to temporarily be a tributary King in Pondoland. Ncapayi took the advice and Faku welcomed the Bhacas, which coincided with the arrival of Nqetho, a Chief of the Qwabes who had moved from Natal to escape King Tshaka's army because he would not serve under King Dingane. When he entered Pondoland and tried to secure land by violence, Faku was anxious to evict him with Ncaphayi's assistance. AmaBhaca drove them back into Natal and Dingane issued an instruction to kill Nqetho. The Thembus' defeat by the Bhacas, Faku to make an arrangement with Ncapayi when the Pondos wanted to attack the Thembus. They entered Thembuland on three occasions and each time succeeded. Soga asserted that cupidity was the force that brought Faku and Ncapayi together and to have destroyed their relationship later. In 1845 Ncapayi attacked Nyanda, the Right Hand section of the Pondos under Ndamase, the son of Faku. He raided Nyanda successfully. King Faku assembled an army and moved against the Bhacas, attacking them on all sides. He drove the Bhacas before him on the ridge kuNowalala. Ncaphayi was wounded and forced off the ridge, landing on a ledge. He was in a helpless condition with both arms broken and a severe assegai wound. He lay there for days, asking those who came to look at him to end his misery. After King Faku gave the order, he was killed.
Conflict with the Afrikaners and the British
In about 1837 Boers arrived in Natal with herds of cattle. Between 1837/39/40, the Boers fought the Bhacas who teamed up with the Bushmen to raid the herds. In about February 1838 the Boers settled in the upland of Natal and began to create the Republic of Natalia. After their victories over Dingane, they extended northward to uMfolozi and St. Lucia Bay. The Boers created arrangements with other kings and therefore did not consider them as enemies. For example, they considered King Faku to be a friendly king and rated Ncapayi as having a powerful military and as a threat. When the Boers came back, they attacked the Bhacas and raided 700 and 50 horses. This is said to have provided the spark for the British intervention in the Bhaca land. An area near Maclear is called Ncapayi land.
