This material was painstakingly compiled by Red Cross volunteers before it was sent on to the soldiers\' home countries. Now these dusty card indexers, forgotten about for 90 years, are the only records of this nature that still remain. In the words of Peter Barton: “To a military historian, this was like finding Tutankhamen\'s tomb and the terracotta warriors on the same day.”
The Red Cross hope to have digital copies of all the records online by 2014. For the full story here is the original BBC link.
