French Emperor Napoleon III assured Confederate diplomat John Slidell that he would make "direct proposition" to Britain for joint recognition. The Emperor made the same assurance to British Members of Parliament John A. Roebuck and John A. Lindsay. Roebuck in turn publicly prepared a bill to submit to Parliament June 30 supporting joint Anglo-French recognition of the Confederacy. "Southerners had a right to be optimistic, or at least hopeful, that their revolution would prevail, or at least endure." Following the double disasters at Vicksburg and Gettysburg in July 1863, the Confederates "suffered a severe loss of confidence in themselves", and withdrew into an interior defensive position. There would be no help from the Europeans.
