The Royal Guernsey Light Infantry was an infantry regiment of the British Army that was formed from the Royal Guernsey Militia in 1916 to serve in World War I. They fought as part of the British 29th Division. Of the 2,280 men, most of whom came from Guernsey, who fought on the Western Front with the RGLI, 327 were killed and 667 were wounded.

Many Guernsey men had already volunteered for regiments in the British Army before the RGLI was formed. The RGLI was created because there was no Guernsey-named regiment to underline the island's devotion to the Crown.

The regimental motto, Diex Aïx, derives from the battle cry used by the Duke of Normandy 1,000 years earlier.

The regiment was disbanded in 1919 but the regimental tradition lives on in the Guernsey Army Cadet Force (Det.) Light Infantry, who, although they do not wear the RGLI cap badge, still keep alive the history of the Regiment within the detachment.

This went according to plan, with few casualties and they then moved into Marcoing and on to the front line at Masnières. The Guernseymen found themselves defending the small town of Les Rues Vertes against a huge and determined German counter-attacks on 30 November, pushed back they retook the village twice in heavy hand to hand fighting that lasted two days. They suffered heavy casualties, with nearly 40% of the regiment either killed, injured or missing during the battle, but only withdrew when ordered to by the high command.
A number of the wounded found themselves returned to Guernsey, to be cared for at the Victoria Military Hospital in Amherst or the Convalescent Hospital at Les Touillets, Castel.

The RGLI is relieved by the Australian 1st Division.

Poetry

See ye Masnières canal a'flood
And where yon green graves lay?
There Norman warriors fled to their God
Ne'er more to glimpse the day.
But writ there, first, a name in blood-
Norman Ten Hundred.

At Doulieu, the night birds flit
Across yon blue-grey water.
And at dusk ghost warriors sit-
Wraiths of a fearsome slaughter.
There too in blood the name is writ-
Norman Ten Hundred.

And thus there the battle's flame
Laid men out fast and low,
So young Sarnia died, but Fame
Cast o'er their graves its glow,
And honours wove about the name
Norman Ten Hundred.

(From Blicq, A Stanley, Norman Ten Hundred, Guernsey Press, 1920)

Commemoration
