Hello everyone,

My father told me that my German grandfather smuggled letters for the resistance against Francisco Franco in the 50s and 60s. He even got caught once and was in a Spanish prison for four weeks. My father did not have a lot of contact with him, and he must have been very secretive about these jobs, so I don't know much more than his name Otto Axtmann and that he was an architect, who worked for the French in their South-German occupation zone because he was one of the few German architects who wasn't member of the Nazi party

I would love to find out more about him, and the Spanish prison might be a good starting point. Do you have any tips on how to approach this? I hope that there are any digitalized archives available.

And since this is a history sub: can you tell me a bit about post WWII fascistic Spain and how the resistance worked during this time?

I am happy about anything you have for me.

EDIT: I just found the privacy rule of this sub. My grandfather died before I was born in 1988.
