P.S. A random synapse fired again to remind me to say that the focus of a narrative history can tend toward the inquiry side (the more interesting pole, in my opinion), or the simple accounting side (or "logos", to use the Greek Herodotus was familiar with and the tradition that he, possibly unwittingly, was altering with his subsequently famous "Inquiry"). Most history written surely falls in between. Either end of the spectrum can be intersting stuff if offering new, additional information or insight, or great compositional style. My personal preference tends, in balance, toward inquiry.
