Thanks John and URC for the links. Interesting stuff to find out there, and yes, Wikipedia has good information too. Yes, it is a shame there aren't any decent books in English on this subject. Perhaps the Swedish publisher Leandoer and Ekholm will come up with a book sooner or later, since they seem interested in the Winter and Continuation war. http://www.leforlag.com/hw_02bocker.asp
I hope they will publish the books they show, and I hope they translate them as well.
