The Prince Regent, after he had become King, did publicly express his fantasies that he had been present at battlefields during the late war. He would embarrass Wellington by claiming, at dinner, to have led a charge at Waterloo. The Duke kept a politic silence.
A politic silence is also best kept about Foulness. It was not a secret military camp in 1813; it is now.
So Sharpe and Harper are back with the army. They, like so many officers and men of that army, now have their wives with them, and they have, at last, breached the defences of France. Wellington is the first foreign General to invade French soil since the very beginning of the Revolutionary War twenty years earlier. There was a feeling, that winter of 1813, that Napoleon would surely sue for peace soon. He was assailed in the north and his beloved France was invaded from the south. But there are battles yet to be fought, and campaigns to be won, so Sharpe and Harper will march again.
