The sheer scale and complexity of the battles of the 1st World War presented new problems over the award of Battle Honours. Battles lasted for weeks or months rather than the day or two of earlier actions. The area covered and number of troops involved, particularly in the major battles of the Western Front, eclipsed anything previously seen. With both the scale and widespread geographical areas of Regimental involvement, the number of Battle Honours that could fairly be claimed was obviously going to be too great to be accommodated on the Regimental Colour on which all pre-1914 Honours were carried. The solution adopted for the Western Front was to award a Battle Honour to cover the major operation and then additional Battle Honours for the supporting actions which contributed to the operation. An example is the Second Battle of Ypres in 1915 which was marked with the Honour Ypres 1915 (to differentiate from Ypres 1914, 1917 and 1918 all of which were awarded as separate Honours) with four supporting Honours, Gravenstafel, St Julien, Frezenberg and Bellewaarde. A further change was that, for the first time, Battle Honours were awarded for a defeat, thus both “Mons” and “Retreat from Mons” appear among those won by the Regiment. Once the list of Battle Honours was agreed by the Honours and Distinctions Committee of the War Office, each Regiment was allowed to select ten, from the total of those awarded, to be carried on the then King’s Colour. These would appear in bold type in the Army List with the remaining in ordinary type.

The Regiment was awarded seventy-nine Battle Honours out of a total of one hundred and sixty eight that were designated. These covered all the campaigns and battles and the many operational theatres in which the Service Battalions of the Regiment served. A Regimental Committee then made recommendations to the War Office for the ten that were to be carried on the King’s Colour. Of these seven were from the Western Front and three, Struma 1918, Gallipoli 1915-16 and Palestine 1917-18 represented the other major operational areas where the battalions of the Regiment served The full list, with the battalions that served there, is shown below. The ten Battle Honours subsequently emblazoned on the King’s Colour are shown in heavy type and capitals. The supporting actions for the main battles have been slightly inset and, where they cover the main battle over a number of years such as Ypres 1915, 1917 and 1918 have been placed within the relevant year with the main action bracketed for guidance:
