Boyd massacre

The Boyd Massacre occurred in 1809 when Māori residents of Whangaroa Harbour in northern New Zealand killed and ate between 66 and 70 people as revenge for the whipping of a young Māori chief^[2] by the crew of the sailing ship Boyd. This was reputedly the highest number of Europeans killed by Māori in a single event, and the incident is also one of the bloodiest instances of cannibalism on record. In retribution,^[3] European whalers attacked the island pa of Chief Te Pahi about 60 km south-east,^[2] in the possibly mistaken belief that he ordered the killings. About 60 Maori and one European died in the clash.^[3] News of the events delayed the first missionary visits to the country, and caused the number of shipping visits to fall to "almost nothing" over the next few years.^[4]
