Searching for Military Records

Britain has been fighting to protect its borders or someone else's for centuries. There have been civil wars and colonial wars. 

Unfortunately, one of the problems with researching military records, particularly in the United Kingdom, is the widespread physical locations of the material. The National Archives (UK) at Kew, West London is as close as you will get to a 'one stop shop' and an excellent place to start. Their informative website has details of the services on offer, as well as detailed research guides and a growing collection of online records. While some research can be done online, most require a personal visit to the National Archives (UK) or, if this is not possible, you can engage a freelance researcher.

Army service records for World War One are available at the National Archives, and many are available via (available for use at the State Library of SA). Sadly, about 60% of the records were destroyed during bombings in 1940, and others suffered badly from fire and water damage. You must, therefore, be prepared for the possibility that the file you are interested in may not have survived.

Locating Military Records


After the restoration of the monarchy in 1660, military records became more plentiful. The main War Office records contain a great deal of information. Records for officers and other ranks up to the start of the 1st World War are kept at the National Archives (UK) at Kew in Richmond, London.

Look through the National Archives research guides online.   

Records since then are in the custody of the Ministry of Defence. For further information, contact the Army Historical Branch, Old War Office Building, London SW1A 2EU.
