Cool Story: Long-Lost Ring, Traded For Chocolate In Wartime, Makes Its Way Home
In the NY Daily News, an AP story:

U.S. Army bomber co-pilot, 2nd Lt. David Cox, traded the ring for chocolate during desperate times as a war captive in one of Adolf Hitler's prisons. Martin Kiss later accepted the ring from his grandparents when he moved to Herrieden, Germany. His American-born neighbor, Mark Turner, helped Kiss return the heirloom.

An excerpt:

After a year and a half behind barbed wire as a prisoner in World War II, 2nd Lt. David C. Cox had just about reached his breaking point.

Deliveries of Red Cross parcels to Stalag VII-A had all but ceased, and the U.S. Army bomber co-pilot and his fellow POWs were subsisting on scanty rations of bug-infested soup and bread. Outside the wire, Adolf Hitler's forces showed no signs of giving up.

Cold and hungry, the North Carolinian made a difficult decision. He slipped the gold aviator's ring -- a gift from his parents -- off his finger and passed it through a fence to an Italian POW, who handed back a couple of chocolate bars.

He would never again see the ring. But it did not disappear.
