During World War II, three percent of the world's population perished in the conflict. Those kinds of massive casualties are so large that they can defy comprehension.
Thankfully, those who did survive shared their stories. The memories of the war, both good and bad, live on in writing, human testimonials, and in collections of artifacts from the battles themselves.
Though the memory of the war lives on, there are still unanswered questions and soldiers who never made it home. Amateur archaeologists in places like Russia often visit battlefields and recover amazing clues to help unlock the past, which is exactly what two men did while on a hiking trip in the Russian countryside.
