In 1968 on New Year's Eve Master Sgt. William H. Cox and his buddy First Sgt. James T. Hollingsworth were holed up in a bunker in the marble mountains of Vietnam.
The two men were hunkered down with rockets and mortars raining down all around them. At that moment the two men made a pact.
If they survive this attack or survived Vietnam, they would contact each other every year on New Years.
For nearly five decades, Cox and Hollingsworth kept their promise to each other.
Earlier this year, Cox kept another promise he made to his friend. He stood guard at Hollingsworth casket and then delivered the eulogy.
By giving the eulogy, he fulfilled his final vow to his comrade.
