Rather than attempt an "illustrative" list, more salient to note that the reason for the revisions lies in the elemental fact that no two eye-witnesses see the same event the same way. Psychological studies in the criminal forensic field, have repeatedly demonstrated the utter unreliability of eye witness accounts due to the psychological fact that memory is malleable and always changing. In addition, few of the investigators can themselves be deemed "impartial". The documentary records that historians rely upon were themselves written by participants who had a variety of less than objective motives. For years, the Soviet blamed the Katyn Massacre on the Germans, who themselves printed up posters accusing the Russians of the barbarous murders of Polish officers, while the Nazi's themselves were liquidating the Polish intelligentsia. This is the stuff of detective work, but not of "indisputable" fact.
