His capture, in January 1546, of George Wishart, an eminently learned and virtuous Protestant preacher, and an intimate associate of the murderous, double- dyed traitor Brunston and of other Lothian pietists of the English party; and his burning of Wishart at St Andrews, on March 1, 1546, sealed the Cardinal's doom.

On May 29th he was surprised in his castle of St Andrews and slain by his former ally, Norman Leslie, Master of Rothes, with Kirkcaldy of Grange, and James Melville who seems to have dealt the final stab after preaching at his powerless victim.

They insulted the corpse, and held St Andrews Castle against all comers.
How gallant a fight Beaton had waged against adversaries how many and multifarious, how murderous, self-seeking, treacherous, and hypocritical, we have seen.

He maintained the independence of Scotland against the most recklessly unscrupulous of assailants, though probably he was rather bent on defending the lost cause of a Church entirely and intolerably corrupt.
The two causes were at the moment inseparable, and, whatever we may think of the Church of Rome, it was not more bloodily inclined than the Church of which Henry was Pope, while it was less illogical, not being the creature of a secular tyrant.

If Henry and his party had won their game, the Church of Scotland would have been Henry's Church--would have been Anglican.
