Britain adopted the Gregorian Calender on 14th September 1752, with the notable exception of The Gwaun Valley, near Fishguard in Pembrokeshire!
The reason for the change was that by 1582, the previous Julian Calender had fallen ten days behind, so Pope Gregory XIII issued a papal bull that from February 24, 1582, the new Gregorian calendar would be the one used by the Catholic world. There were unsuccessful attempts in Britain to address the problem in 1645 and 1699 but in 1752 it was finally decided that October 4th would be followed by October 15th.
However, people in the Gwaun Valley did not accept the change and continued to celebrate New Year, which they called Hen Galan on 13th January.
On 14th September 1914 the 'Cardiff Pals' marched to war.
At the end of August 1914, it was decided that the British Army needed an additional 100,000 volunteers in the war against Germany, so in an experimental move, they allowed groups of friends to enlist and serve in units together.
These units proved extremely popular, becoming known as the Pals Battalions and on 14th September 1914, the Cardiff Pals were seen off to war by hundreds of people lining the streets. The Cardiff Pals went on to fight in Salonika for three years, defending Macedonia, northern Greece and the Aegean ports from German and Bulgarian forces. Tragically they suffered almost 100 casualties in one assault on 18th September 1918, barely two months before the end of the war ended. The devastating impact of such losses to individual communities led to the disbanding of Pals Battalions for future conflicts.
For risking his own life, by going under enemy fire to rescue his senior officer and then carrying him 100 yards to safety at the First Battle of the Aisne in northern France on this day in 1914, Lance Corporal William Charles Fuller,from Laugharne became the first Welshman of World War I to be awarded the Victoria Cross.
The Bishop Gore Secondary school in Swansea was founded on 14th September 1682 by Hugh Gore (1613–1691), Bishop of Waterford and Lismore.
