Incredible World War Two colour footage shows wounded marines being evacuated from the beaches of Iwo Jima
The vast, silent collection was shot with hand-held cameras, giving the images an eerie and life-like feel, providing a fascinating insight into army life during some of the bloodiest periods in American military history.
American marines overcame more than 20,000 Japanese Imperial Army troops in heavily fortified positions on the island of Iwo Jima in five weeks of bloody fighting in February 1945.
Only a handful of defenders survived the American capture of the island, which was a major US objective in the Pacific war given its proximity to the Japanese mainland.
But American forces suffered heavy losses at the hands of the desperate Japanese soldiers.

The video shows in fascinating detail military vehicles transporting badly injured Marines on stretchers to waiting vessels on a beach.
Jeeps carrying dozens of troops and amphibious vehicles are also shown driving through the dark sand of the volcanic island.
The never-before-seen images also show Marines at the 1968 siege of Khe Sanh in Vietnam, at Guadalcanal – the scene of another bloody Second World War battle – and in 1950 at the Chosin Reservoir in Korea.
