This conversation took place while I was writing my despatches to Sir Henry Hotham; and the Frenchmen were walking in the cabin, frequently interrupting me, to enforce their statement of Buonaparte's situation being by no means so desperate as might be supposed; from which I took the liberty of drawing a conclusion directly opposite to the one they were desirous of impressing on my mind. Captain Knight, of the Falmouth, who carried my despatches to the Admiral, was present during the whole of this conversation, but did not join in it. This was the first certain information I had received of Buonaparte's position since the battle of Waterloo. Tuesday, the 11th.--About noon, a small boat came off from the Island of Oleron, to where the ship was at anchor in Basque Roads, rowed by four men, in which sat two respectable-looking countrymen, who asked for the Captain; and upon my being pointed out to them, requested to speak with me in private. When shown into the cabin, where I went accompanied by Captain Gambier, of the Myrmidon, they acquainted me, that a message had been sent from Isle d'Aix, early that morning, for a man who was considered the best pilot on the island for the Mamusson passage, being the only person that had ever taken a frigate through; that a large sum of money had been offered to him to pilot a vessel to sea from that passage, and that it certainly was Buonaparte's intention to escape from thence; either in the corvette, which had moved down some days before, or in a Danish brig, which was then lying at anchor near the entrance. On receiving this information, I immediately got under weigh, and though the flood-tide had just made in, beat the ships out of the Pertuis d'Antioche before it was dark, when I sent the Myrmidon off the Mamusson, with orders to anchor close in with the entrance, when the weather would admit of it; while I remained with the Bellerophon and Slaney, which rejoined me that evening, under weigh between the light-houses. On the 12th of July, the Cyrus being seen in the offing, I ordered her by telegraph to take a position close in with the Baleine light-house, and to examine strictly every vessel that might attempt to put to sea from the Pertuis de Breton, as Buonaparte was on the spot, endeavouring to escape to America. The same evening, the white flag made its appearance for the first time on the towers of Rochelle; on seeing which, I felt it my duty to run into Basque Roads, accompanied by the Slaney; and having anchored, I hoisted the Bourbon colours at the main-top-gallant mast-head, and fired a royal salute. During the whole of this afternoon, however, two tri-coloured flags were kept flying in Rochelle; and before sunset all the white flags were struck, and every where replaced by those of Buonaparte.
