Roy Hallums
Supply Corp Commander, U.S. Navy

Via The Spokesman-Review...

Roy Hallums was enduring his 311th day of captivity, blindfolded, his hands and feet bound, stuffed into a hole under the floor of a farm building outside Baghdad. He heard a commotion upstairs and managed to get the blindfold off. Delta Force troops broke open the hatch. An American soldier jumped down.

“He looks at me and points and says, ‘Are you Roy?’ I say ‘yes,’ and he yells back up the stairs: ‘Jackpot!’ ”
