18th , 1313
Robert I, (Roibert a Briuis in medieval Gaelic, Raibeart Bruis in modern Scottish Gaelic and Robert de Brus or Robert de Bruys in Norman French), usually known in modern English today as Robert the Bruce (11 July 1274 – 7 June 1329), was King of Scotland (1306 – 1329).
In 1313 Robert the Bruce, being King of Scotland, landed at Ramsey, and, marching via Douglas, laid siege to Castle Rushen Despite the Keep having been strengthened by the addition of the west and south towers, Castle Rushen was besieged and taken by the Scottish King, Robert the Bruce - though he could not successfully hold it. A period of confusion followed. Scotland and England both claimed the overlordship and nominees of each nation held the Island from time to time. Eventually, the Kings of England prevailed over the Scots and granted the Lordship of Mann to various English noblemen.
So by 1313, Robert the Bruce has had a series of victories and reconquered Scotland from the highlands to Perth and the Isle of Man. A weakly Edward II anxiously clutches at his collar, and decides not to invest in Glaswegian real estate after all.
