Archaeologists will also try to match up artefacts found with some of the bodies
Progress is being made on a massive project to identify the bodies of hundreds of soldiers - including many of the Glosters - who died in the First World War.
It's thought around 60 soldiers from Gloucestershire were involved in the Battle of Fromelles in France, 1916, but many who died were buried without proper graves.
"It does answer the question about what happened to a lot of the soldiers who were recovered by the Germans," said Paul Cobb, a historian from Lechlade who specialises in the Battle of Fromelles.
"They certainly played a significant part in as much as they had battalions in the front line in the British part of the offensive.
"Unfortunately their success was limited because the German wire wasn't destroyed by artillary, but nevertheless, the Glosters fought very well although they did sustain quite high casualties."
DNA tests are being carried out on the remains and the results will be matched with genetic samples taken from living relatives.
The exhumed bodies will later be buried with full military honours.
The grave was found after detective work by an Australian historian and the work on the grave is being supervised by the Commonwealth War Graves Commission.
