As dozens of their players left the gridiron for battlefields overseas, the cities of Philadelphia and Pittsburgh joined forces to keep the decimated NFL squads up and running.

In December 1942, a week before Christmas, the Allied governments issued a statement exposing a monstrous chain of events in Nazi-occupied Europe.

Tens of thousands of Allied civilians, including children, were caught in the crossfire of World War II in the Pacific and interned in camps such as Santo Tomas in the Philippines.

Desperate for slave labor to continue the doomed war effort and fearful of camp survivors exposing Nazi crimes, German decision-makers put in motion nearly three-quarters of a million concentration camp prisoners. Of this number, 250,000 died in these death marches.

Torn and warped by Japanese bullets, this piece of protective gear is a rare testament to the ferocious fighting of the oft-forgotten Aleutian Islands Campaign.
