sure, but even in your example, the "what" (and to some degree, the "who") are outlined. the veracity can often be debated, but those are pretty common in historical documents. even if it was from a biased (on either side) source, i think it's pretty rare to see a complete absence of the action. from what i've read, it's often the "whys" and "hows" that end up lost to time. "whens" are often inconsistent too
