Corbeyran de Cardaillac de Sarlabous was a 16th-century French soldier who served in Scotland as Captain of Dunbar Castle, and was Governor of Le Havre for twenty years. He was usually called Captain Sarlabous in Scottish and English letters of his time. A contemporary French writer calls him the "sieur de Sarlaboz." Sarlabous is a place in the Hautes-Pyrénées where Corbeyran held lands.
Born around 1515 in Gascony, his father was Odet de Cardaillac, seigneur de Sarlabous, and his mother, Jeanne de Binos, heiress of Bize or Vize.
Captain Sarlabous arrived in Scotland in 1549 under Paul de Thermes to resist the English in the war of the Rough Wooing. He was posted first at Dumbarton Castle, then made Captain of Dunbar in 1553. Henri Cleutin wrote to Mary of Guise saying he did not know Sarlabous personally but the appointment was at the recommendation of the Duke of Guise. In August 1554 Sarlabous joined the Earl of Argyll at Dunstaffnage Castle in an unsuccessful expedition to Mull against James McConill, McClane, and their whole "folkis."
On his return to France, in 1558 he served the Duke of Guise at the siege of Thionville. He returned to Scotland to resist the Scottish Reformation. John Knox and the Protestant Lords of the Congregation sent letters from Perth to "Serra La Burse" and other French soldiers on 22 May 1559, asking them to desist from attacking "us natural Scottishmen." Sarlabous and Henri Cleutin were confronted by a Protestant force of 3,000 at Cupar Muir in June, and on Christmas Day 1559 he took part in the recapture of Stirling Castle from the Lords of the Congregation.
