Note 563 — MONDAY, SEPTEMBER 13.
Reading edition
It seems that the Pretender was only once in London, and that it was in 1750. Ante, i. 279, note 5. I suspect that 1759 is Boswell's mistake or his printer's. From what Johnson goes on to say it is clear that George II. was in Germany at the time of the Prince's secret visit. He was there the greater part of 1750, but not in 1753 or 1759. In 1750, moreover, 'the great army of the King of Prussia overawed Hanover.' Smollett's England, iii. 297. This explains what Johnson says about the King of Prussia stopping the army in Germany.
