Major critical material… the Cork

It was already known that the Portuguese wolfram was a strategicall product during the war. The discussion involving this mineral took several hours of meetings between the Portuguese ruler Salazar and the Allies or the Axis personnel.


This news cut published in November 29, 1942 in the “Sauk Centre Herald” reveals that Portugal was exporting another strategicall product: Cork…

The army and navy munitions board even talk about a “major critical material”… “all imported from Portugal”.

One of those things… who would imagine that a tree would be so important.
