A bloody history
In 2013, two mass graves were unearthed at Durham University, and scientists now say the once-mysterious graves hold the remains of Scottish soldiers who were captured and held prisoner after the Battle of Dunbar in 1650.
New clues are helping archaeologists piece together who the soldiers were and how they died. The research is ongoing, but already the bones are helping researchers learn more about one of the shortest but bloodiest battles of the English Civil Wars.

The skeletons were found in 2013, during an excavation on campus for a proposed addition to the school's library.
Battle of Dunbar
The two mass graves beneath Durham University had been hidden for nearly four centuries. The prisoners were captured by Oliver Cromwell during the Battle of Dunbar in 1650, and many died from hunger or disease, the archaeologists said.

The teeth in some individuals were worn, a sign that they enjoyed smoking a pipe, according to the archaeologists.
A tale of teeth

The archaeologists noted that the skeletons showed very little evidence of healed trauma, which suggests the soldiers didn't have much combat experience before they were sent to fight in the Battle of Dunbar.
Scientific tests revealed that human remains found in mass graves are those of 17th-century Scottish soldiers.
