Murdoch Stewart's captivity in England did not prevent his father from ruthlessly pursuing the family interest, often through violent means. On 26 March 1402 the Duke of Albany's nephew,
David Stewart, Duke of Rothesay, had died in
Falkland Palace while under his uncle's protection. King Robert III of Scotland, fearful that his younger son Prince James, the
heir to the throne of Scotland, would suffer the same fate, sent him out of the kingdom to escape Albany's clutches. In 1406 James boarded the
Maryenknyght, a ship from
Danzig that was bound for
France, but on 22 March 1406, the ship was taken by English pirates off
Flamborough Head and James was delivered as a prisoner to King
Henry IV of England. Soon afterwards, on 4 April 1406
King Robert III died, leaving Scotland without a King. Prince James, now the heir to the throne of Scotland and just 12 years old, would endure 18 years of detention in England. In his absence the Albany Stewarts took the reins of power, and Murdoch's father,
Robert Stewart, Duke of Albany, became
Governor of Scotland, king in all but name. The English price of returning James to Scotland was English overlordship of Scotland, something that few Scots were prepared to accept. At this time Murdoch Stewart was still a prisoner in England, but in 1416 he was exchanged for
Henry Percy, 2nd Earl of Northumberland, and he returned to Scotland. The Albany Stewarts took James's lands under their own control, depriving the king of income and any of the
regalia of his position. James was referred to in the official records as merely "the son of the late king".
Governor of Scotland and Duke of Albany In 1420, on his father's death, Murdoch, now aged 58, finally inherited the
Dukedom of Albany. He also inherited the
Earldom of Fife and the
Earldom of Menteith, and at last became
Governor of Scotland in his own right. He would hold this position from 1420 to 1424, while King James I was still held captive in England. Few serious attempts appear to have been made by Duke Albany to return James to Scotland, but eventually political pressure compelled Murdoch to agree to a general council.
Ransom and return of James I , victor of the
Battle of Bauge. , where Albany's brother
John Stewart, Earl of Buchan was killed and his army totally annihilated by the English. In August 1423 it was agreed that an embassy should be sent to England to negotiate James's release. A ransom treaty of 60,000
marks (an enormous sum) was agreed at
Durham on 28 March 1424, to which James attached his own seal – he and his queen, accompanied by an escort of English and Scottish nobles, proceeded to
Melrose Abbey, arriving on 5 April where he met Albany to receive the governor's seal of office. Upon the return of
James I to Scotland, Albany lost his position as Regent. James began to consolidate his position. His
coronation took place at
Scone on 21 May 1424. At his coronation parliament the king – probably with the intent of securing a cohesive political community loyal to the crown – knighted 18 prominent nobles including Albany's son Alexander Stewart. At this stage, it is probable that the king felt unable to take action against the Albany Stewarts while Murdoch's brother,
John Stewart, Earl of Buchan and
Archibald Douglas, 4th Earl of Douglas were fighting the English in
France alongside their
Dauphinist French allies. Buchan was a soldier with an international reputation and commanded the large Scottish army of around 6,000 men, a formidable force. In addition, he was
Constable of France, making him the effective commander of the entire French army. However, both he and Douglas were killed at the
Battle of Verneuil in August 1424 and the Scottish army was routed – the loss of these Albany allies with their fighting force left Murdoch politically exposed. James moved swiftly against his Albany Stewart relatives soon afterwards.
Arrest Murdoch was arrested, along with his younger son Lord Alexander Stewart. Albany was at first confined in the castle at
St. Andrews and afterwards transferred to
Caerlaverock Castle. His wife Isabella was captured in the family's fortified castle of
Doune, their favourite residence, and committed to
Tantallon Castle. James's older brother
David Stewart, Duke of Rothesay had died young, in
Falkland Castle, while in the care of Murdoch's father,
Robert Stewart, Duke of Albany. Though Albany had been exonerated by Parliament, the suspicion of foul play remained. Moreover, neither Duke Robert nor his son Murdoch had exerted themselves in negotiating James's release while in English captivity. This may well have left James with the suspicion that the Albany Stewarts had personal designs on the throne of Scotland. At this time Albany's other son Walter was already in prison. James, Murdoch's youngest son (also known as
James the Fat), escaped arrest. and fled into the
Lennox, where he began to organise a revolt, leading men of Lennox and Argyll in open rebellion against the crown. He attacked and burned the burgh of
Dumbarton with much loss of life. This resort to violence by Albany's youngest son may spurred the king into bringing a charge of treason against the Albany Stewarts, however, it is likely there was other evidence (no longer extant) for him to have gained the support of the leading magnates. == Trial and execution ==
