The original camp (Palm Beach) needs to be located.  The site here is in the Huaorani territory.

Operation Auca

Operation Auca was an attempt by five Evangelical Christian missionaries from the United States to bring Christianity to the Huaorani people of the rainforest of Ecuador. The Huaorani, also known by the pejorative Aucas (a modification of awqa, the Quechua word for "savages"), were an isolated tribe known for their violence, against both their own people and outsiders who entered their territory. With the intention of being the first Christians to evangelize the previously uncontacted Huaorani, the missionaries began making regular flights over Huaorani settlements in September 1955, dropping gifts. After several months of exchanging gifts, on January 3, 1956, the missionaries established a camp at "Palm Beach", a sandbar along the Curaray River, a few kilometres from Huaorani settlements. Their efforts came to an end on January 8, 1956, when all five—Jim Elliot, Nate Saint, Ed McCully, Peter Fleming, and Roger Youderian—were attacked and speared by a group of Huaorani warriors. The news of their deaths was broadcast around the world, and Life magazine covered the event with a photo essay.
