Interesting but I have not found other clues to confirm this piece of information:

On Griffiths´ " Marshal Petain" it is claimed that Franco offered to join the nazis in June 1940 as he thought the battle was over in the west (!!). According to the author Franco believed he could get French territory for joining the "war". The Germans however did not show much interest at the time. Later in autumn the situation was different and Franco would not join the axis even if Hitler asked him to.
