North Irish Horse war diaries

The commander of every British Army unit was required to keep a record of each day's events while on overseas service in time of war. This was to include important orders, despatches and instructions, location, duties of staff, the weather, state of the roads and ground, casualties and the comings and goings of officers, "all matters of importance, military and political", and "in what respect organizations and regulations have stood the test of war". Commanders interpreted these instructions very differently, perhaps depending on the administrative diligence of their staff. Lieutenant-Colonel Cole, for example, often though it sufficient to make a single monthly entry for A Squadron and the 1st Regiment North Irish Horse ("Humbercourt. Corps Cavalry duties"). Others found time to record detailed accounts of everything from the movement of clothing requisitions to the score in the inter-Battalion football match.

A typical war diary page is shown below. This one, from the 9th Battalion Royal Irish Fusiliers, records that on 25 September 1917 "304 O.R. from NORTH IRISH HORSE joined Battn today, our Band playing them in to RUYAULCOURT where they were toasted right royally."

The original War Diaries for all North Irish Horse and associated units in the First World War are held in the National Archives at Kew, London. The attached transcriptions have been taken from images of the originals kindly provided by Hugh Vaugh.

The transcriptions are, to the extent possible, word-for-word, with the following exceptions. For ease of reading and clarity I have standardised capitalisation and some punctuation, corrected obvious spelling errors, spelled-out most acronyms and replaced abbreviations with full text. In all cases where the meaning is not clear or may be subject to alternative interpretations, I have retained the original. No doubt there are some errors - these are mine alone.
