Preparation for the Battle of Epehy Wood:
|The following are from documents held at the National Archives as part of the War Diary of the 24th Battalion, London Regiment and originally marked as SECRET. These are instructions to the 173rd Infantry Brigade for the attack on Epehy and dated the 16th September 1918 - two days before the attack and an addendum to the instructions for the attack regarding "paragraph 4 Communications" dated the 17th September 1918. The instructions are type-written and the typewriter used would appear to have a worn 'e' - the letter 'e' sometimes appearing as an 'o'. Where I am sure that the correct letter is an 'e' I have entered an 'e'. Where I am not certain whether the letter is an 'e' or an 'o' I have used an 'o'.|
