This is a brief guide to researching British army records for an officer after 1913. The National Archives has a substantial collection of records covering this period, but many other documents were destroyed or badly damaged. Some service records are still held by the Ministry of Defence. Officer ranks include Lieutenant, Captain, Major, Colonel, Brigadier and General. The Ministry of Defence website has more detail.

1. What do I need to know before I start?

The National Archives does not hold army service records for the Second World War. They are still with the Ministry of Defence.

There are over 217,000 British Army officers‘ service records for the First World War held by The National Archives. An officer’s file originally had three parts but two of these were destroyed by enemy action in September 1940. What remains was heavily weeded prior to 1940 and in many cases this means that nothing remains for many officers.

2. What records can I see online?

Not all officers applied for their campaign medals, so if an officer did not apply, there will be no medal index card. The campaign medal roll usually contains the same information as the medal index card, but it may also give the battalion number.

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 (£).

Officers’ service records (1914-1922)

Search our catalogue for references to officers’ service records by name in record series WO 339 and WO 374:

The content of the files varies – some have simply a note of the date of death whilst others contain attestation papers for those commissioned from the ranks, a record of service, personal correspondence and other items.

Alternatively, click on the links below to search more specifically for references to:

  • records of officers who finished serving before 1922, by first and last name in WO 339. WO 339 includes officers who were given a temporary commission in the regular army, those who were commissioned into the Special Reserve of officers and those who were regular army officers before the war.
  • records of officers given a Territorial Army commission or a temporary commission, by first and last name, regiment and rank, in WO 374.
  • officer’s long numbers in the online indexes in WO 338 – this is only worthwhile if you have not found anything in WO 339 or WO 374 (please be aware that the online indexes are very large files and only suitable for download on a fast and unlimited broadband connection). Long numbers for officers in the WO 374 series start with the first letter of the surname and the first vowel of the surname. The number for Anderson, for example will start with AE (references starting with a P refer to records which are still held by the Ministry of Defence). To search WO 374 with an officers name and number, remove the initials from the number. For example if the long number is AE/279, simply search for Anderson 279.
