Good sources for Hitler helping Franco in the Spanish Civil War

by thefuryofficial

I need some good sources for an internal assesment, about Hitler's aid to Franco in the Spanish Civil War.

Thanks a lot

A good overview is found in Antony Beevor's The Spanish Civil War. I would recommend reading the pertinent chapter there, and then going to the sources he used to be more in-depth.
