While Slidell was talking with the Emperor, he had in his pocket a letter from J. A. Roebuck, an English politician who wished to force the issue in the House of Commons. As a preliminary to moving the recognition of the Confederacy, he wanted authority to deny a rumor going the rounds in London, to the effect that Napoleon had taken position against intervention. Napoleon, when he had seen the letter, began a negotiation of some sort with this politician. It is needless to enter into the complications that ensued, the subsequent recriminations, and the question as to just what Napoleon promised at this time and how many of his promises he broke. He was a diplomat of the old school, the school of lying as a fine art. He permitted Roebuck to come over to Paris for an audience, and Roebuck went away with the impression that Napoleon could be relied upon to back up a new movement for recognition. When, however, Roebuck brought the matter before the Commons at the end of the month and encountered an opposition from the Government that seemed to imply an understanding with Napoleon which was different from his own, he withdrew his motion (in July). Once more the scale turned against the Confederacy, and Gettysburg was supplemented by the seizure of the Laird rams by the British authorities. These events explain the bitter turn given to Confederate feeling toward England in the latter part of 1863. On the 4th of August Benjamin wrote to Mason that "the perusal of the recent debates in Parliament satisfies the President" that Mason's "continued residence in London is neither conducive to the interests nor consistent with the dignity of this government," and directed him to withdraw to Paris. Confederate feeling, as it cooled toward England, warmed toward France. Napoleon's Mexican scheme, including the offer of a ready-made imperial crown to Maximilian, the brother of the Emperor of Austria, was fully understood at Richmond; and with Napoleon's need of an American ally, Southern hope revived. It was further strengthened by a pamphlet which was translated and distributed in the South as a newspaper article under the title France, Mexico, and the Confederate States. The reputed author, Michel Chevalier, was an imperial senator, another member of the Napoleon ring, and highly trusted by his shifty master. The pamphlet, which emphasized the importance of Southern independence as a condition of Napoleon's "beneficent aims" in Mexico, was held to have been inspired, and the imperial denial was regarded as a mere matter of form.
