He recently left the military, which he joined at the age of 16, and decided to sell the medal, along with six others, to support his family.
Now 39, he said he was “very happy” with the award and added: “It will really help secure a new home for my family.”
Describing his actions in Iraq, he said: “I started running across the bridge and they saw me immediately.
“They were lying down, lying down, shooting at me as I ran; I saw their fingers on the triggers, then the muzzle flashed and I could hear the bullets go by.
“I remember thinking, ‘Why don’t they hit me?'”
Only 60 CGCs have been awarded to date, including 15 for the Iraq war. The medals were auctioned along with a copy of David Rowland’s painting of the recipient winning his CGC and a folder containing 15 letters of congratulations.
