I live near the sites where the fighting was going on, to this day can be found residues after them. Most of my colleagues go out to the mountains to "explore the stories." I also collect photos of those fights too ...... that claimed so many lives ..... http://en.wikipedia.org/wiki/Battle_of_the_Dukla_Pass
Somewhat off topic but pictures of the battlefields as they are now are well recieved on this forum. If you live near one or are visiting one PLS consider taking pictures and posting them. If you are unsure how to help is available on the admin subforum.
