Buchan's brutal assault on Moray in 1390 was to some extent intended to extricate himself from Fife's domination but turned out to be unsuccessful—Alexander was to lose his Lordship of Urquhart in 1392 and then his claim on Ross following his wife's divorce in 1392. Fife's influence waned during the mid-1390s while that of King Robert and his son David, Earl of Carrick increased—the King took back responsibility for Scottish-English relations and had manoeuvred the Red Douglas Earl of Angus into a dominating position in southeastern Scotland at the expense of Fife's ally, the Black Douglas. Although Fife's authority over Scottish affairs had lessened he still exercised considerable power in government. Fife and Carrick both campaigned against Buchan and his sons and other lawless elements in the west and north. Although, Buchan appeared to have halted his violent traits after this, his sons did not. A fight ensued near Pitlochry involving Duncan and Robert Stewart at the head of a band of caterans, when Sir Walter Ogilvie and Walter de Lychton and followers were killed. Later it is recorded that three sons of Buchan's were imprisoned in Stirling Castle from 1396 to 1402 and Alexander Grant theorises that Buchan's low profile during the 1390s might have been because of his sons' incarceration.
