Does anyone dispute the accuracy of this song?

They came in a blizzard, we offered them heat
A roof for their heads, dry shoes for their feet
We wined them and dined them, they ate of our meat
And they slept in the house of MacDonald.

Chorus:
O, cruel was the snow that sweeps Glencoe
And covers the grave o' Donald
O, cruel was the foe that raped Glencoe
And murdered the house of MacDonald

2. They came from Fort William with murder in mind
The Campbell had orders King William had signed
"Put all to the sword" these words underlined
"And leave none alive called MacDonald"
Chorus:

3. They came in the night when the men were asleep
This band of Argyles, through snow soft and deep
Like murdering foxes amongst helpless sheep
They slaughtered the house of MacDonald
Chorus:

4. Some died in their beds at the hand of the foe
Some fled in the night and were lost in the snow
Some lived to accuse him who struck the first blow
But gone was the house of MacDonald
Chorus:

In 1688, William of Orange convinced the English Parliament to oust the current King James VII of Scotland and of England and install William himself as regent. At the time, England and Scotland were a boiling cauldron of national and religious animosities, not only between the two countries but amongst political factions and the clans themselves.

A minor event in history was the appropriation of MacDonald property by the Campbells. The MacDonalds felt free to reclaim cattle which they still considered their own. The Campbells called them reivers and no love was lost between the clans.

Then King William demanded an oath of loyalty by all clan chiefs with a deadline of 1. January 1692. MacDonald Clan Chief MacIain of Glencoe, leaving this distasteful necessity to the last moment, made his way to Fort William on 31. December 1691. Glencoe presented himself to Colonel Hill the governor, asking him to administer the required oath of allegiance. Hill told Glencoe that he must go to Inveraray, which wasn't easy in deep mid-winter snow, and mountainous terrain, so he was late. This appears to have been a premeditated plot, involving secret letters, ignored letters of free passage and other skullduggery by the current political officials. They gleefully planned to make an example of the Ian MacDonalds at Glen Coe and the Campbells were not in the least reluctant to assist in the execution of this plan.

With instructions to kill every man of the Glen Coe clan under 70 (approximately 200), Campbell of Glenlyon and some 128 soldiers, of various clans, including Campbells, called on MacDonald, said they were in the area to collect taxes and asked his hospitality. For 12 days they had a spontaneous ceilidh, ate the MacDonalds' winter food supply, drank to each other's health and made marriage plans between the young ones.

Exactly according to plan, at five o'clock on the morning of 13. February 1692 Campbell of Glenlyon and his soldiers rose from their beds to massacre their hosts.

They managed to kill "only" 38, including some women, children and an 80-year-old man, but some escaped and women and children were sent naked, into a sudden blizzard, from their razed and looted homes.

This event is still much debated today

The monument to the fallen MacDonalds is situated in the Glencoe village, and MacIain was buried on the island of Eilean Munde, in Loch Leven, near the entrance to the Glen.
