scene of the second sweep. The accounts of Vietnamese witnesses are consistent on several points with Rood's. Ba Thanh, the guerrilla killed while carrying the B-40 rocket launcher, was "big and strong" and in his late 20s. Return fire was also intense, according to Vo Van Tam, who was then a local Viet Cong commander: "I led Ba Thanh's comrades, the whole unit, to fight back. And we ran around the back and fought the Americans from behind. We worked with the city soldiers to fire on the American boats." No Vietnamese witnesses saw how Thanh died or saw him being chased by an American. No individual who was present that day has disputed Kerry's version of events, nor suggested that he did not earn the Silver Star, and some said accounts given in Unfit for Command were incorrect. O'Neill states that the Silver Star was awarded after only two days, "with no review".

However, in its October 2004 documentation of its investigation of Kerry's medals, the office of the Navy inspector general described the first, longer version as the "COMUSNAVFOR Vietnam version, signed by VADM Zumwalt" and the second version as the "official version, signed by the delegated award authority, ADM Hyland, CINCPACFLT". As to the third version, the report described it as one of several "duplicate citations" that were issued in 1985 after "considerable correspondence indicating efforts over the years to chase down various citations", and stated that the ones under Lehman's name were likely signed by machine. In addition, in October 2004, Rowan Scarborough of the Washington Times reported: Commenting on the Silver Star issue, Republican Sen. John Warner, who was Undersecretary of the Navy at the time, stated "We did extraordinary, careful checking on that type of medal, a very high
