10th Battalion, The Durham Light Infantry, War Diary May 1940

In view of the complexity of the War Diary for this crucial month in the Brigade's existence it is recommended that the Diaries for each of the Units concerned are read alongside each other, so as to form as accurate a picture as possible of what was a confusing few weeks. The entries are kept in date order and, where clarity would be helped, the reader is referred to parallel entries from other Units. It is suggested that the Diary for the 23rd Division is read first, followed by that for the Brigade HQ and then the Infantry Battalions and Engineer Companies. There is a considerable amount of material to cover, especially as Units were in many cases broken into small parties and served as part of temporary groupings, such as Petreforce. The author has tried to be as faithful as possible to the original documents.
