Sort of reminds me of the Piet Retief story. Seems the more things change the more they stay the same.
Dingane asked that Retief and his party retrieve some cattle stolen from him by a local chief. This Retief and his men did, returning on 3 February 1838. The next day, a treaty was signed, wherein Dingane ceded all the land south of the Tugela River to the Mzimvubu River to the Voortrekkers. Celebrations followed. On 6 February, at the end of the celebrations, Retief's party were invited to a dance, and asked to leave their weapons behind. At the peak of the dance, Dingane leapt to his feet and yelled "Bambani aba thakathi!"(isiZulu for "Kill the wizards"). Retief and his men were overpowered, taken to the nearby hill kwaMatiwane, and executed. It is believed that they were killed for withholding some of the cattle they recovered. Dingane's army then attacked and massacred a group of 500 Voortrekker men, women and children camped nearby. The site of this massacre is today called Weenen, (Dutch for "to weep").
