The Earl of Elgin, lately ambassador of Great Britain at the Porte, had, contrary to the usage among civilized nations, been seized upon with his family as he passed through the French territory; and during the period of which we are treating, he was residing upon his parole near Pau, in the south of France, as one of the _Détenus_. Shortly after the arrest of Moreau, Georges, &c., an order arrived for committing his lordship to close custody, in reprisal, it was said, of severities exercised in England on the French General Boyer. The truth was, that the affair of General Boyer had been satisfactorily explained to the French Government. In the Parisian papers, on the contrary, his lordship's imprisonment was ascribed to barbarities which he was said to have instigated against the French prisoners of war in Turkey--a charge totally without foundation. Lord Elgin was, however, transferred to the strong castle of Lourdes, situated on the descent of the Pyrenees, where the commandant received him, though a familiar acquaintance, with the reserve and coldness of an entire stranger. Attempts were made by this gentleman and his lieutenant to exasperate the feelings which must naturally agitate the mind of a man torn from the bosom of his family, and committed to close custody in a remote fortress, where the accommodation was as miserable as the castle itself was gloomy, strong, and ominously secluded from the world. They failed, however, in extracting from their prisoner any expressions of violence or impatience, however warranted by the usage to which he was subjected. After a few days' confinement, a sergeant of the guard delivered to Lord Elgin a letter, the writer of which informed him, that, being his fellow prisoner, and confined in a secluded dungeon, he regretted he could not wait on his lordship, but that when he walked in the court-yard, he could have conversation with him at the window of his room. Justly suspecting this communication, Lord Elgin destroyed the letter; and while he gave the sergeant a louis-d'or, told him, that if he or any of his comrades should again bring him any secret letter or message, he would inform the commandant of the circumstance. Shortly afterwards, the commandant of the fortress, in conversation with Lord Elgin, spoke of the prisoner in question as a person whose health was suffering for want of exercise; and next day his lordship saw the individual walking in the court-yard before his window. He manifested every disposition to engage his lordship in conversation, which Lord Elgin successfully avoided.
