Ever since the Crowned Heads arrived, London has been mad, & as full again as ever I knew it. Where all the people are lodged I cannot imagine. The streets are full day and night watching the Royals, who see everything and therefore are always upon the move.

The King of Prussia walked quietly into St George's Church yesterday and asked for the Duke of Devonshire's pew. They have all been at Oxford where the Prince was with them and was received with great applause.

Since I began my letter I have been some hours at Mrs Macdonald's to see a Review in the Park where the Regent and the Crowned Heads attended. The day is beautiful and the scene was very fine, for there were thousands of spectators on foot, as horses and carriages were not admitted into the Park. I was not near enough to distinguish Philip & he has not yet returned….

I have been interrupted again. Philip is to go with the Prince to- morrow to Portsmouth which he likes the idea of extremely. He has been much entertained with the duty of to-day….

After all, the Regent did not go to the House of Lords and the Emperor does not leave London to-day, therefore Philip will have a little rest after the fatigues of yesterday, for he did not get home from the ball till between five and six, and is now asleep.

To console London for the termination of such a round of dissipation, on July 1st White's Club gave a magnificent masquerade at Burlington House in honour of the Duke of Wellington, to which the Stanhopes went with their friends, the Kinnairds. Nearly two thousand persons were accommodated in the temporary room which was erected for supper, and the costumes were remarkable for their magnificence, save possibly that of Byron, who was clad, sombrely but effectively, in the dark flowing robes of a monk. A guest of gayer, if less dignified appearance, was Sir Lumley Skeffington, who, as usual, encountered the ill-fortune which seemed to dog his footsteps, for his red Guard's coat was mischievously torn from his shoulders by crazy Lady Caroline Lamb. [9] who hid it and left the discomforted beau in his waistcoat in the centre of the ballroom.

Eight months after these festivities, news arrived in London that on March 1st, 1815, Napoleon had once more landed in France, followed by the intelligence that on March 20th he had entered Paris. In June the Campaign of Waterloo began by the defeat of Blucher at Ligny, where John Stanhope had so long resided. But on the 18th of the same month, "The fops of Piccadilly became the heroes of Waterloo," and that famous victory decided for all time the fate of the Conqueror of Europe. Four days later he again abdicated, and on July 15th he surrendered himself to the English.

Mrs Spencer-Stanhope to John Spencer-Stanhope. July 28th.

What great and surprising events have happened in little more than a month. The Battle of Waterloo was one of the bravest & greatest ever fought, & has decided the fate of Europe, therefore though we must lament the many gallant men who fell on that dreadful day, yet not a life was lost in vain, & when we consider what the blood would have been had the Campaign continued, we must look upon the loss as small.

The surrender of Bonaparte is such an unexpected event, that I can scarcely yet credit it, for I never supposed he would have lived to have become a Prisoner. What will be done with him? Thank Heaven we can now confidently look forward to Peace.
