Searching for Vimy’s Lost Soldiers premieres Sunday, April 9 at 9 p.m. ET/PT on HISTORY.

Searching for Vimy’s Lost Soldiers follows Norm Christie, one of the world’s leading experts in identifying missing allied soldiers of the First and Second World Wars, and his team as they embark on an extraordinary investigation – to locate the bodies of 44 missing Canadian soldiers. The soldiers are believed to be buried in an old German mine crater (known as Crater CA40) beneath a farmer’s field in northern France that is currently slated for industrial development. Determining the exact location of Crater CA40 must be done soon, but the task of excavating CA40 will be dangerous as the ground is full of unexploded bombs, explosive shells, and chemical weapons. Joined by a team of geophysicists, bomb disposal experts, and the families of the lost soldiers, Christie is determined to find the missing men and give them the proper commemoration they deserve.
