How to research a soldier of the British Army in WW1 > Operational records (War Diaries)

Each unit and formation of the army was obliged to maintain a daily record of its activities, called the War Diary. The entries in the diaries vary from very terse, simple statements like 'Continued training' to very detailed explanations of actions which can run to several pages. Officers are frequently mentioned by name, men of the 'other ranks' much less so unless they did something remarkable. The original diaries are kept at National Archives in Kew, in the category WO95. Some examples are on this site.

 

As a visitor to the National Archives, you will be able to access these diaries. Some are now digitised and available through DocumentsOnline. They represent a truly remarkable archive, each consisting of many sheets of foolscap, written usually in indelible pencil. Some contain scraps of maps, operation orders, personal notes, and so on. If you have any knowledge about Grandad's dates (like the date he was killed or wounded, or even just 'I know he was in Ypres in 1917'), you will be able to identify quite precisely where he was and what happened to the unit. The War Diaries were used as the basis for many of the regimental and other histories including the Official History.

 

If you have identified Grandpa's regiment or corps, but not yet his battalion or other sub-unit, then try the regimental listings for the infantry, artillery, engineers and other units on this site.

War Diaries and other documents describing an action use the British Army's trench map coding.
