I have read that a German U-boat refueling at Villa Cisneros was attacked and sunk. I have also read that After Germany Invaded Russia in 1941 a Japanese technical mission returning to Japan was flown to Rio de Janiro via Vila Cisneros on the Atlantic coast. According to a book The "Nazi Menace" in Argentina, 1931-1947 By Ronald C. Newton, A German General was flown to Argentina to organise former crew members of the Graff Spee who escaped captivity in Uruguay into building an airstrip at Cordoba for receiving long range flights from Germany.
Prior to WW2 and up until Brazil joined the Alliance against Germany in 1943, vila Cisneros was a regular waypoint for trans-Atlantic flights by the Italian airline LATI.
Please can anybody enlarge upon this issue and provide any sources for further reading?
What role did Vila Cisneros play in the later half of WW2?
