The background of the war can be traced as far back as World War II. Great Britain and the Celtic Union were on opposing sides of the war, and the former found itself defeated and occupied after the war. Wales was occupied as well. The people of Great Britain and Wales hated the occupation of their homelands by the hated enemy.
In 1968 rebels blew up the George Street Bridge in Newport, Wales, beginning the thirty year conflict known as The Troubles. The occupying Celtics fought against the Welsh rebels, known as the Welsh Republican Army (WRA). Bombings, skirmishes, and battles raged all across Wales. In 1998, the rebels finally conquered Cardiff, ending Celtic control in southern Wales. The two powers signed a peace treaty, and southern Wales got independence. The capture of only southern Wales got many angry in Wales, and calls for liberating all over Wales and eventually Great Britain were heard. In 2000, Wales answered that called with its surprise invasion of northern Wales.
The Beginning of the War
The invasion (code named Operation Northern Strike) began on December 12, 2000. Attacks were committed by Wales all across the northern border. The Welsh in Northern Wales also rose up in rebellion. The Welsh attacked Ystradgnlais in order to gain its coal deposits, and it was a military stronghold. The attack came in the first minutes of the war, and caught the Celtics off guard. Ystradgnlais was taken.
The Welsh then moved on and attack Knighton on December 19, the headquarters of the Celtic Third Army. The attack was repulsed with heavy casualties for both sides. 12 days later on the 31st, the Welsh attacked with the aid of rebels. The Celtic Third Army, which was spread thin due to the attacks, was defeated and forced to retreat. Knighton was taken.
