First checks before you go further

A casualty entry gives numbers, and sometimes names and circumstances, for a date and an action. Match it to the casualty record and the service record before treating it as the full story of one person.

If you hold only a place, start with the records for that place, not with a surname search across the whole country. Place is a filter, and a strong one. If a search floods you with results, add the date range before you add anything else. Dates are the fastest way to cut a flood to a list. One dated fact from a record outweighs three plausible details from a story, and the timeline should show which is which.

The order to work in

The steps below assume you have already fixed the person, the number, and the dates as far as you can. If you have not, do that first, and then return. A good session ends with the next step already named. If you finish a step without knowing the next one, the timeline, not the record, is telling you. Keep three lists apart as you work: what you know, what you suspect, and what you do not know. Research goes wrong when a suspicion is written into the timeline as if it were a fact.

StepWhat to do
1Fix the battalion and the dates from the personal file before opening any diary.
2Open the battalion diary for those dates, and note its reference.
3Read entries day by day around the dates that matter, including appendices and maps.
4Move to brigade or division diaries only where the battalion diary is thin or missing.

Reading what the record actually says

Cross-references inside a file, see another sheet, another number, another unit, are the file telling you where its own gaps are filled. Follow them. A name in a unit document proves presence only when name, rank, role and dates all match the person you are researching, not when the surname alone matches. Read the whole entry before you decide what any single line means. A line read alone can support a story the full entry contradicts.

Common traps in this record type

The common dead ends here are a shared name, a variant spelling, a thin record for the dates you need, and a unit that cannot be fixed from the clues available. Each dead end here is a normal research outcome, not a personal failure, and each one points to a next check rather than to a conclusion. A record written later, summarising earlier service, can introduce errors that the original sheets do not contain. Where they disagree, prefer the sheet written at the time.

What should you check next?

Let the question this record raised choose the next record. A record opened out of curiosity, rather than out of a question, rarely advances a timeline. A session that ends with three referenced facts and one named next step has succeeded, even if the story feels shorter than you hoped. A research project ends, properly, not with a flourish but with a referenced timeline and a list of questions still open.
