The screaming skeletons of dozens of soldiers who were killed during a battle 150 years ago have been discovered in a mass grave in eastern Poland.

The screaming skeletons of dozens of Russian soldiers who were killed during a battle 150 years ago have been discovered in a mass grave in eastern Poland.

The remains were unearthed by archaeologists on the site of the Battle of Zyrzyn, off the S17 Lublin-Warsaw expressway in Zerdz, eastern Poland.

The Russian soldiers had been transporting cargo worth 200,000 roubles (£2,500) when they were killed by Polish forces in 1863.

Photographs show the skeleton’s mouths wide open as they lie alongside one another at the site of the battlefield.

Archaeologists believe that about eighty soldiers, presumed to be Russian, were buried in the mass grave.

Nearly 200 Russian soldiers were killed during the battle, with 282 captured as prisoners of war. Around 90 of the 500 soldiers managed to escape when they encountered Polish troops.
