King James III. wrought many improvements at the castle. The Parliament Hall, which is still in existence, dates from his reign, and was probably designed by Cochrane. A new chapel was built at this time, and the King intended to make it a collegiate church, but its erection to that dignity did not take place till his son had been some years upon the throne. His interest in the welfare of the Chapel Royal was the occasion, though not the main cause of James’s fall. He endeavoured to attach to it the revenues of Coldingham Priory, a religious house in the Merse, in the country of the Homes and Hepburns. Patrick and James Home, however, had already annexed the funds, which they considered were their due, and they determined to resist an encroachment on their rights. The alliance of the Hepburns with the Homes was the beginning of the insurrection that soon spread far and wide, involving among other lords the Earls of Angus and Argyll. The King at once made preparations for the struggle. Having placed his son, the Duke of Rothesay, in Stirling Castle, under the care of Shaw of Sauchie, he journeyed to the north to raise the subjects whom he knew to be loyally disposed. During the King’s absence the rebels secured the person of the heir-apparent, who was treacherously handed over by the fickle Shaw. James returned south with a large army to meet the insurgents at Blackness, where a skirmish and a subsequent pacification took place. Hostilities, however, broke out afresh. The King was refused admittance to Stirling Castle, and the rebel army was advancing from Falkirk. A battle called Sauchieburn or the Field of Stirling was fought near Bannockburn, on June 11th, 1488, in which the charges of the Border spears eventually drove the King’s Highlanders from the field, and during the flight the unhappy monarch was overtaken and slain. His body was buried near the High Altar in the Abbey of Cambuskenneth, where his Queen Consort, Margaret of Denmark, had not long before been interred. The engagement at Sauchieburn is interesting as being the only occasion in Scottish history in which Highlanders and Borderers were opponents on the field of battle. The rebel Duke of Rothesay, a lad in his sixteenth year, mounted the throne as King James IV. in his luckless father’s room. Soon after his accession he visited Stirling Castle and there expressed contrition for his part in the late insurrection, but a few months later he gave the keeping of the fortress to the traitor, Shaw of Sauchie. All through his later life, however, James IV. felt remorse for his conduct towards his father, and he often retired from Holyrood to Stirling when fits of depression were upon him.
