Another thing to worry about while hiking through the jungle. The Smithsonian writes:
In October 1941, FBI director J. Edgar Hoover received a strange bit of war intelligence in a classified document, warning that a secret German airbase had gone up deep in the heart of the Amazon rainforest. Particularly concerned about an attack on the Panama Canal, the FBI began collaborating with Brazil’s secret police.
In December, another worrying message came: the suspected culprits behind the scheme were a colony of German monks, [possibly] preparing for a secret base for the Luftwaffe, the airborne arm of the German military. The following July, large amounts of fuel were spotted traveling upriver in Bolivia. The FBI worried that the fuel could be headed to the secret jungle airbase, still yet to be discovered.
In the end, military leaders concluded that stockpiling enough supplies deep within the jungle would not be possible. The would-be Nazi monks were left to live their own quiet, solitary lives in nature.
