February 13th, 1692, is still remembered in the Western Highlands of Scotland. At 5 a.m. a blizzard was raging down the valley of Glencoe but there were soldiers about. They were two companies of the Argylls under Captain Robert Campbell of Glenlyon, peaceably billetted on the MacDonalds of Glencoe for the past two weeks. The MacDonalds, who had newly sworn allegiance to King William of Orange, had treated them well. Sacred bonds of hospitality had been forged – a reassuring sign that enmities were fading between MacDonalds and Campbells and between Highland supporters of the Stuarts and the new Edinburgh government of 1688. But that was illusion. Captain Campbell had received secret instructions the previous day. ‘Sir, You are hereby ordered to fall upon the rebels, the MacDonalds of Glencoe, and to put all to the sword under seventy… This you are to put in execution at five of the clock precisely… This is by the King's special command, for the good and safety of the country, that these miscreants be cut off root and branch…’ At five of the clock precisely the Argylls turned on their hosts. Almost forty MacDonalds were killed on the spot and many more, who scrambled away up the bleak walls of the glen, died of exposure in the blizzard. Crofts were burnt, cattle and goods carried off. That was the infamous Massacre of Glencoe. I shall start from here and gradually follow the moral questions which arise into the arena of politics at large.
