Sir Duncan Campbell (1597–1645), 2nd Baronet and 6th Lord of Auchinbreck, was a Scottish landowner and soldier. He was commander of the Marquess of Argyll, Archibald Campbell's troops, (Covenanters) in Ireland.

He was a son of Sir Dugald Campbell, 1st Baronet of Auchinbreck and Mary Erskine. He was recalled by Archibald Campbell to Scotland and placed in command of the Covenanter troops at the Battle of Inverlochy (1645).

Duncan Campbell was born circa 1597 in Colquhoun, Dunbartonshire, Scotland. He was the second son of Dugald Campbell of Auchinbreck and Mary Erskine, and succeeded him in 1641.^[1] He bought Carnasserie Castle from the Marquess of Argyll in 1643.

He served in Parliament for Argyllshire from 1628 to 1643.^[1]

During the Irish Wars of the early 1640s, Campbell led his Covenanter troops from Argyll in the massacre of many local Catholic MacDonalds on Rathlin Island.^[2] On 2 February 1645, back in Scotland, he led Argyll’s troops at Inverlochy where he was taken prisoner and killed, probably in retaliation for his massacre of the Catholic MacDonalds a few years earlier.^[1]

Battle of Inverlochy 1645

On 2 February, Sir Duncan Campbell led Argyll's troops at the Battle of Inverlochy (1645) where he was taken prisoner and executed by Alasdair Mac Colla.

One prisoner who would receive no mercy was Duncan Campbell, Lord Auchinbreck, the functional commander of the covenanters that day. Auchinbreck had ravaged the lands of Alasdair Mac Colla's Irish cousins in Antrim as a commander in the Scottish army in Ireland. Also he had plotted to assassinate Alasdair when Alasdair tried to reconcile with the Scottish army following the defeat at Glen Maquin. Now Alasdair had Auchinbreck brought before him. Alasdair offered Auchinbreck two choices, to be made longer, that is hanged, or made shorter, that is decapitated. Auchinbreck reportedly replied, "da dhiu gun aon roghain," which could be roughly translated as two worst alternatives without one choice. At this point Alasdair swung his two handed sword, and took off the top of Auchinbreck's head above the ears like the top of a soft-boiled egg.

His sister, known as Fionnghal Chaimbeul, wrote a Gaelic lament on the battle of Inverlochy where her brother was killed, and her eldest Hector Roy Maclean fought on the opposing side.^[3]
