What a chronology actually proves

A chronology is not a story. It is a test of whether your account survives contact with your own documents, and where the record falls silent.

People arrive with a chronology in mind. They have lived it, so they can recite it. The difficulty is that a recited chronology and an evidenced one are different objects, and only one of them is any use to a reader who was not there.

A chronology built properly does something uncomfortable and valuable at the same time. Every line has to be sourced to a document and a page. If the line cannot be sourced, it does not go in the chronology — it goes in the gap analysis, which is a different document with a different purpose.

That discipline produces three findings almost every time. First, events that felt central turn out to be undocumented. Second, events nobody mentioned turn out to be decisive, because they establish who knew what and when. Third, the sequence itself is often wrong: not dishonestly, but because memory compresses months into a single impression.

None of this decides who was right. A chronology is not a verdict. What it does is make the argument possible, because a reader can now follow it without taking anything on trust. That is the entire point. If your position is sound, an evidenced chronology is the fastest way to show it. If it is not sound, you would rather find out from us than from the person on the other side of the table.
