Re: If I recall...
Appears to be untrue, according to this document.
The Logistics of the British Recovery of the Falkland Islands 1982
"The United States’ level of co-operation went far beyond allowing the British use of the runway at Wideawake, including by granting them almost complete access to the airfield’s 1,200,000 US gallons of aviation fuel stocks, and later by agreeing to the British storing their own fuel stocks in the facilities at Wideawake."
Still, nice story.
