Which Dates Decide Where an Army Record Is Held?

Service dates decide the likely holder, because transfer programmes move older records to The National Archives over time. Check the current holder guidance for the exact dates before approaching any holder.

First checks before you go further

Service dates decide the likely holder, because transfer programmes move older records to The National Archives over time. Check the current holder guidance for the exact dates before approaching any holder.

Search for the person you can prove, not the person you hope to find. The provable person has a number, a unit and a date range; the hoped-for person has only a story. Do not open five records at once. Open one, extract what it actually says, write it down with its reference, and only then open the next.

The order to work in

Do not start with the record that interests you most. Start with the record that anchors the timeline, and let interest follow the anchor. Do not let a tool, a website, or an index set the order of your work. Tools serve steps; steps do not serve tools. Keep the original spelling of every name and place in your notes, even where you are confident of the modern form. Searches need originals.

StepWhat to do
1Fix the service dates first, so you know which holder is likely to hold the file.
2Note the regiment or corps and the service number together, exactly as written.
3List postings and transfers in date order, and treat each transfer as a new thread to check.
4Test every later record, medal, casualty or war diary entry, against the personal file before adding it to the timeline.

How to read this kind of entry

The order of sheets in a file is not always the order of events. Rebuild the date order yourself, and do not trust filing order to do it for you. Check whether an entry was written by the unit, by a clerk, or by a later compiler. The writer decides how much weight the entry can carry. If an entry puzzles you, date it first and interpret it second. Most misreadings here come from carrying a later meaning backwards.

Where this kind of research usually stalls

A record set described as complete usually means complete for its own purpose, not complete for yours. Check what the set was made to record. When a record set ends before your dates, or begins after them, the problem is coverage, and no variation of search terms will fix a coverage problem.

A search that returns nothing proves only that nothing matched those terms in that catalogue on that day. It does not prove the record does not exist. When every avenue returns the same dead end, the dead end itself is information: it tells you where the record system stops, and that boundary is worth noting.

What should you check next?

Check the holder current guidance before any next step that involves a request, a copy, or a visit. Guidance changes, and a step planned on old guidance wastes a session. A timeline should end each session with a named next step, not with a vague intention to look further. Name the record, the reference, and the question.

Keep the person, the number and the dates together as you move to the next record, and re-check them on arrival. Filters drift when they are carried in memory. A timeline that can be retraced, reference by reference, is the goal. Everything else, story included, is secondary to that.

Primary sources for this guide

This guide keeps its claims general and points to the official holders, so the holder itself is the place to check the current position. It is general educational information only, not personal professional advice, and it offers no record lookup service and no determination of any individual's service.

Please note: Only deceased persons are covered here, and the privacy of living people is respected throughout: nothing on this site identifies a living person from a service record. Where a holder's process is described, use the holder's current guidance for your case.
