Here's more: Others in the ad back up that account. Jack Chenoweth, who was a Lieutenant (junior grade) commanding PCF-3, said Kerry's boat "fled the scene" after a mine blast disabled PCF-3, and returned only later "when it was apparent that there was no return fire." And Larry Thurlow, who says he commanded a third Swift Boat that day, says "Kerry fled while we stayed to fight," and returned only later "after no return fire occurred."
Fine, but none of this is answering my question:
Does Thurlow's Bronze Star Citation talk about enemy fire?
