How to look for records of... Army regiments

This guide contains advice on locating records of British Army regiments, as opposed to records of individual soldiers. Regimental records are varied, sometimes incomplete and held in a variety of places.

What do I need to know before I start?

Many regiments have changed their identities, some merging with other regiments, over the course of their history. These name changes and amalgamations mean it can sometimes be complicated tracing a regiment and its records.

Each regiment has its own place in the British Army hierarchy – known as the ‘regimental order of precedence’ – which can affect how its records are organised in relation to those of other regiments.

Local archives and regimental museums hold a wealth of information on specific army regiments. You can find the correct repository through the Find an archive database.

First World War unit war diaries (1914–1923)

Search Discovery, our catalogue, for selected unit war diaries (WO 95) for a British or colonial regiment which served in the First World War. You may need to try several different keywords or an asterisk when searching, for example, ‘Bucks’ may produce different results to ‘Buckinghamshire’.

Access the rest of the unit war diaries at The National Archives at Kew. Unit war diaries do not generally contain biographical information.

Records available only at The National Archives in Kew

To access these records you will either need to visit us, pay for research (£) or, where you can identify a specific record reference, order a copy (£).
