[9] See account by Decazes in E. Daudet, _Louis XVIII. et le duc Decazes_, pp. 48-49, and an interesting "secret and confidential" letter of Castlereagh to Liverpool (July 8, 1815) in the unpublished Foreign Office records: "The king sent for the duke and me this evening to the Thuilleries.... We found him in a state of great emotion and exaltation at the reception he had met with from his subjects, which appears to have been even more animated than on his former entrance. Indeed, during the long audience to which we were admitted, it was almost impossible to converse, so loud were the shouts of the people in the Thuilleries Gardens, which were full, though it was then dark. Previous to the king's dismissing us, he carried the duke and me to the open window. Candles were then brought, which enabled the people to see the king with the duke by his side. They ran from all parts of the Gardens, and formed a solid mass of an immense extent, rending the air with acclamations. The town is very generally illuminated, and I understand from men who have traversed the principal streets that every demonstration of joy was manifested by the inhabitants." [10] It is as yet not proved that Blacas returned from his embassy in response to a summons from the Ultras. But whether it was on his own initiative or not, there can be no doubt as to the hopes which they built on his arrival (see Daudet, _Louis XVIII. et le duc Decazes_).
