I absolutely agree. An example in the Indian Territory is the "assumption" that Phillips Expedition of Feb 1864 was coming down the Texas Road to Middle Boggy near present Atoka OK. Makes sense except that none of Phillips reports mention being on the Texas Road or at any point on it but instead mention Little River and Old Fort Holmes and that he sent forage and a squad of men to North Fork Town (on the Texas Road) to meet the balance of the 14th KS Cavalry which, per Phillips he never heard from. Regardless, the assumption has stuck and there is a regular reenactment near Atoka and an elaborate description on the OHS website which, as far as I can determine, is not supported by any period documentation.
As you say, there are as many versions of an event as there are eyes that viewed it. That can be a good thing as it rounds out an overall understanding by comparing and combining the pieces. By collecting as many sources as we can, we can also reasonably draw conclusions as to the accuracy of individual accounts. In the Indian Territory, we are lucky to find one primary source that we must accept with a bit of healthy skepticism.
