1. Why use this guide?
This guide will help you find records at The National Archives relating to military operations planned and carried out by the British Army since the end of the Second World War.
This is not the place to find advice on looking for personnel records. For British Army service records covering the period since the Second World War, all of which are held by the Ministry of Defence, go to the Veterans UK website.
2. Essential information
There are broadly two different types of British Army operations records. Those created by units of the army itself and those created by politicians, top-ranking officers and other high-level personnel.
In the First and Second World Wars, unit records were generally in the form of war diaries but by 1950 unit diaries had been largely superseded by alternative forms of record keeping.
There are countless published regimental histories and these are often a good place to start research into British Army operations - see Further reading for some examples of regimental history books.
3. How to conduct a general search
You can search Discovery, our catalogue, using keywords.
However, not all of the records have been given specific or detailed descriptions in our catalogue (some, for example, may be catalogued as 'Miscellaneous', or other generic descriptions) so keyword searches will not always find everything on that subject.
Nevertheless, keyword searching can be a good way to begin. Try searching by:
- name of operation or campaign (for example, 'Operation Corporate')
- name of a conflict (for example, 'Suez crisis' or 'Korean War') - keyword searches like this work best if you put them in inverted commas
- name of army unit. If you are looking for war diaries or other records related to specific British Army regiments and other units - these are often recorded in our catalogue using abbreviations so try a variety of terms when searching (for example, 'Regt' as well as 'Regiment', 'Bn' as well as 'Battalion, 'Bty' as well as 'Battery')
If you use the Advanced search option you can focus your search by entering an appropriate date range and/or the reference for a particular department such as WO for War Office.
Alternatively, you can do a keyword-only search and then filter your results using the options on the left of the results page.
4. Politics, policy and planning: records of high command
To find records revealing the decision making behind British Army operations, government policy on a specific conflict and all kinds of other high level thinking around the operations, conflicts and wars involving the British Army, search within Cabinet (CAB) and Ministry of Defence (DEFE) departments.

5. Unit records in the aftermath of the Second World War
