Feldgrau.net

Greetings everyone. I've translated an article on Slovakian military in WW2, which is found at http://feldgrau.com/a-slovakia.html. The question is: do I have permission to use it on my blog which is ad-free and I make no profit? I've already posted the translated article and at the beginning I'm giving the link to orginal article, but I can take it down if the author wants me to do. Best regards.

Here's my blog (it's in Turkish): http://muharebegunlugu.blogspot.com.tr
