This is a brief guide to researching records of British army regiments. Regimental records are varied, sometimes incomplete and can be complicated. They are held in a variety of places. This guide will help you to find out if the information you are looking for exists, and if it does where to find it or more information about it. This guide is for people interested in regiments themselves as opposed to those interested in finding a specific person.

What do I need to know before I start?

Try to find out:

  • the identity (name and number) of the regiment
  • a date range and location to help focus your search

What records can I see online?

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.

What records can I find at The National Archives at Kew?

Regimental muster books, pay lists and records (c1730-1991)

Search our catalogue by regiment name, number or county for a regimental muster book or pay list between c1730 and 1898 (WO 10, WO 11, WO 12, WO 13WO 14, WO 16, WO 68, WO 69) or for other regimental records between 1737 and 1991 (WO 379 and WO 380). These are arranged by unit type, regiment and date. They are also incomplete.

Second World War unit war diaries (1938-1947)

Refer to section 5 in the research guide  British Army operations in the Second World War for a list of series containing unit war diaries for the Second World War. Unit war diaries do not generally contain biographical information.

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 (£).

Did you know?

Regiments are likely to have changed their identities and merged with other regiments throughout their history. Due to name changes and amalgamations, it can sometimes be complicated to trace a regiment and its records.

Each regiment has its own place in the 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.
