Filed under Army War Diaries: A Method Guide
First checks before you go further
A war diary is the official daily record of a unit, covering movements, orders, operations, casualties and administration. It was written for the unit, so most entries name officers and events, not every other rank by name.
Do not let a familiar surname carry the search. In a large record set, a familiar surname is the weakest filter you have. A search term that returns nothing in one catalogue may return everything in another, because catalogues index different fields. Try the holder catalogue directly.
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. If an entry seems to contradict the previous entry, read the entries between them. The contradiction often dissolves into a transfer, a posting, or a correction. A rank shown without a date is a snapshot, not a career. Find the date it belonged to before you use it to place the person anywhere.
What are the common dead ends?
If the person you seek shares a name with a well-known figure in the same unit, published material will favour the famous namesake. Original records will not. If the dates you have are approximate, say so, and search a range rather than a single year. A record filed under a neighbouring year is a common miss.
- A diary that names officers but not other ranks.
- A gap in the diary for the exact dates you need.
- A period place name that has since changed.
- A brigade or division diary mistaken for a battalion diary.
What to open after this one
Before you open the next record, write down what you expect it to show and what would surprise you. That note is what turns reading into testing. A next step chosen from curiosity will entertain you. A next step chosen from the timeline will advance it. Prefer the timeline.
If the next record is a unit record, carry the posting dates with you. If it is a personal record, carry the number. The filter you carry decides what you find. The best next step is the smallest one that answers a real question. Grand searches rarely beat a single well-chosen record.
