Letters of Harriet, Countess Granville. To Lady G. Morpeth [aged 32]. Saltram: September 1, 1815,
I went yesterday to the slate quarry and all over the beautiful wood in which it is. The day was delicious, and this part of the country is beautiful. It puts me in mind of Bolton and some of the valleys between Theux and Spa.
We had a dinner, Sir John Duckworth, another Sir Something, and a sensible, pleasing physician whom they swear by here.
The Boringdons saw the Pole who has been allowed to go with Buonaparte. He seems really attached to him. Amongst other things he said of him, ' Mais il ne pense jamais k lui,' a new view of his character. There are different versions of all the stories of him and his companions. Some say that Madame Bertrand1 is very much in love with him, others that she detests him, and never calls him anything but I'homme.
Borino [aged 43]2 is so long manoeuvring and marshalling us that I have time to tell you that I had a letter from my aunt. She had just seen the Hollands, Lady H. in grief at the failure of some presents she wanted to send to Buonaparte and Madame Bertrand.
No women were present at the Duchess of Cumberland's [aged 37] marriage. The Dowager Lansdowne proposed herself, and was refused. Caroline William [aged 29] writes me word that she detests Paris, which she says is gay without interest, noisy beyond bearing; that she is magnificently but uncomfortably lodged, alone or in a crowd; and that every countenance bears the stamp of suppressed ill-humour if native, pique if Austrian or Russian, open insolence or vulgar wonder if English, with the only exception of Hart, who sees everything couleur de rose and enjoys himself extremely. The Louvre, she says, is the prey of the spoiler, and Denon3 looking as Jenny's mother did when 'she looked in her face till her heart was nigh to break.' Good-bye.
Note 1. Wife of Comte Bertrand, Buonaparte's secretary. They both accompanied him to St. Helena and were present at his death.
Note 2. Lord Boringdon.
Note 3. Celebrated for his knowledge of art. He accompanied Buonaparte to Egypt, and was on his return named Director- General of the Museums, and retained the place till 1815. He had collected in the conquered countries a great number of works of art, with which he enriched the museums of France.

William of Worcester's Chronicle of England
William of Worcester, born around 1415, and died around 1482 was secretary to John Fastolf, the renowned soldier of the Hundred Years War, during which time he collected documents, letters, and wrote a record of events. Following their return to England in 1440 William was witness to major events. Twice in his chronicle he uses the first person: 1. when writing about the murder of Thomas, 7th Baron Scales, in 1460, he writes '… and I saw him lying naked in the cemetery near the porch of the church of St. Mary Overie in Southwark …' and 2. describing King Edward IV's entry into London in 1461 he writes '… proclaimed that all the people themselves were to recognize and acknowledge Edward as king. I was present and heard this, and immediately went down with them into the city'. William’s Chronicle is rich in detail. It is the source of much information about the Wars of the Roses, including the term 'Diabolical Marriage' to describe the marriage of Queen Elizabeth Woodville’s brother John’s marriage to Katherine, Dowager Duchess of Norfolk, he aged twenty, she sixty-five or more, and the story about a paper crown being placed in mockery on the severed head of Richard, 3rd Duke of York.
