"I was assured," writes the Chevalier Johnstone, (who differed from his General, Lord George,) "on good authority, when I was in London, some time after our unfortunate defeat, that the Duke of Newcastle, then Secretary of State for the War Department, remained inaccessible in his own house the whole of the 6th of December, weighing in his mind the part which it would be most prudent for him to take, and even uncertain whether he should not instantly declare himself for the Pretender. It was even said at London, that fifty thousand men had actually left that city to meet the Prince and join his army, and every body in the capital was of opinion, that, if we had beaten the Duke of Cumberland, the army of Finchley Common would have dispersed of its own accord, and that by advancing rapidly to London, we might have taken possession of that city without the least resistance from the inhabitants, and without exchanging a single shot with the soldiers. Thus a revolution would have been effected in England, so glorious for the few Scotchmen by whom it was attempted, and altogether so surprising, that the world would not have comprehended it. It is true, the English were altogether ignorant of the number of our army, from the care we took in our marches to conceal it; and it was almost impossible for their spies ever to discover it, as we generally arrived in the towns at nightfall, and left them before the break of day. In all the English newspapers our numbers were uniformly stated as high as twelve or fifteen thousand men. Under such circumstances, some temporary advantages might have been gained by marching southwards; for it is now believed that the Jacobite party in England were much more numerous than we have generally understood; and that thousands would have flocked to the standard of Charles Edward had he been accompanied by a sufficient force to authorise the expectation of his success."
