The attack on heavily fortified German positions on July 19/20, 1916 was, however, a disaster, leaving 5,500 Australian and 1,500 British troops dead or injured.
The missing 399 troops were known to be among the dead because their bodies were recovered by the Germans and their names and personal belongings passed to their families via the Red Cross. However, their final resting place remained a mystery, despite repeated attempts to locate them.
Now, however, after scouring German wartime archives in Munich and carrying out extensive surveys of the area around Fromelles using geophysics, radar, topographic surveys and metal detectors, historians from Glasgow University's Archaeology Centre for Battlefield Studies are confident they have found the "lost army".
I guess they must have some rationale for reburial, but I wonder why their present resting place is unsuitable. Seems like a nice little area that one could landscape a bit and put up a marker.
