 After attacking and capturing York in 866AD, either the boneless turned his attention north to a 350 million year old volcanic plug that rises 240 feet above the River Clyde, known as Dunbarton Rock. This rock was the capital of the All Clue, meaning Rock of the Clyde, which was an early kingdom of what later was referred to as the Kingdom of Strathclyde, which was largely made up of Celtic Britons. The region in which they occupied was known as the Hen Oglev in Old Welsh, meaning Old North, and the people spoke Cumbric, a variant of the common Brithonic language, with Cumbric thought to be closely related to modern Welsh. This led to these people often being referred to as Cumbrians who occupied the southwest region of what we call Scotland today. Dunbarton, meaning Fort of the Britons, was a defensive stronghold of the Old Clue, with Dunbarton Rock allowing them to control the shipping trade along the River Clyde, long considered a prized fort. Dunbarton Rock was attacked several times before the Vikings, including by a coordinated attack by the Picks and the Angles a century or so prior to the Vikings. Either the boneless was not alone in his Viking assault on Dunbarton Rock, as he teamed up with the Viking ruler of Dublin, Olaf the White. At this point, it's important to note that there is some debate about exactly who these Viking leaders were. Some sources say that the two leaders of the Viking campaign in Dunbarton were Aimer and Amlay Kunung, although Aimer may simply be a different name for Ivar and Amla Kunung, just another name for Olaf. With this being said, Ivar marched his army north from York, whilst Olaf sailed from Ireland and along the River Clyde. Hebridean Vikings were also likely to have fought alongside Ivar and Olaf. The ensuing siege lasted for four months, and eventually resulted in the Britons of Dunbarton being starved into surrender. North Sagas claimed that the Old Clue water well eventually dried up, leaving them with no choice but to surrender. The Vikings then stormed and plundered the fort, taking every valuable treasure they could get their hands on. This treasure was then put on a fleet of 200 ships along with captured slaves, which set sail for Ireland. The King of the Old Clue, Artgal Mac Dumagall, was taken prisoner and potentially killed in Dublin in 872 AD as a favour to the Picts who looked to exert their influence over the Kingdom of Strathclyde. The Old Clue did survive however, with Govan becoming an important centre of the Kingdom of Strathclyde for a century or so, until the Kingdom of Strathclyde was absorbed into the Gaelic-speaking Kingdom of Alipa or Alba in the 11th century AD.
