In May 1372, Owain Lawgoch announced in Paris his intention of claiming the throne of Wales.   

Owain Lawgoch (Owain ap Thomas ap Rhodri), the grandson of Llywelyn ap Gruffydd's brother Rhodri,  was directly descended from the Royal House of Gwynedd. 

In 1370 Owain declared himself Prince of Gwynedd and with the help of the French, assembled a fleet with the intention of sailing for Wales. The ships were split up in bad weather and the invasion was abandoned.  Two years later he tried again, but again the weather turned against him and the fleet reached no further than Guernsey.  At this point the English despatched a Scot by the name of Jon Lamb to assassinate Owain and having infiltrated Owain's band of men, he succeeded during the siege of Mortagne in 1378.  So ended the entire line of Wales’s most illustrious royal house.

Lynn Davies CBE , 1964 Long Jump Olympic champion. Lynn was also the 1996 European Champion and flag bearer at the 1968 Olympics, being later elected President of the UK Athletics Members Council.  

Born this day 1364 at Alnwick Castle, Northumberland,

Sir Henry Percy (Harry Hotspur), ally of Owain Glyndwr.

Percy's military achievements brought him much favour with Richard ll, but he switched sides to support Henry Bolingbroke in his attempt to overthrow Richard, and when Henry became King Henry IV, Hotspur and his father were rewarded with extensive responsibility in both the east march and North Wales.

1401 The Glyndwr revolt began to spread throughout North and Central Wales, thwarting Hotspur's attempts to maintain control.

1402   Henry IV appointed Hotspur royal lieutenant in North Wales, but the Percy's were becoming discontented with Henry IV, and it was at this time that the Percys, Glyndwr and Edmund Mortimer starting discussing the "Tripartite Indenture" which divided England and Wales between the three of them.

1403  Hotspur accused the King of 'tyrannical government' and  marched to Shrewsbury to do battle against Henry IV's son the future Henry V.  However Percy was killed and his body was put on display. He was posthumously declared a traitor, with his lands being claimed by the Crown.  

On this day 2009, William Windsor (Billy), the goat of the 1st Battalion of the Royal Welsh infantry, retired due to old age. Soldiers from the battalion lined the route from his pen to the trailer as he left the camp for the last time.

*  Billy is not regarded as a mascot, but a serving lance corporal, meaning that soldiers of lower rank are required to stand to attention when Billy walks by. His duty was to march at the head of the battalion on ceremonial occasions.

*  The tradition of the goat originated in 1775, when a wild goat walked onto the battlefield during the Battle of Bunker Hill in the American Revolutionary War. 

*  He was demoted to fusilier for a three-month period in 2006, after inappropriate behaviour during the Queen's Official Birthday Celebrations, when he failed to keep in step and tried to headbutt a drummer.

*  The royal goat herd was presented to the Queen by the Shah of Persia, and they are kept on Llandudno's Great Orme.

*  His replacement, also called William Windsor, began as a fusilier whilst being trained for military life, receiving a ration of two cigarettes per day, which he eats, but is not permitted Guinness until he is older.
