In fact, the Confederates had lost militarily and also politically. During the final hours of the battle, Confederate Vice President Alexander Stephens was approaching the Union lines at Norfolk, Virginia, under a flag of truce. Although his formal instructions from Confederate President Jefferson Davis had limited his powers to negotiate on prisoner exchanges and other procedural matters, historian James M. McPherson speculates that he had informal goals of presenting peace overtures. Davis had hoped that Stephens would reach Washington from the south while Lee's victorious army was marching toward it from the north. President Lincoln, upon hearing of the Gettysburg results, refused Stephens's request to pass through the lines. Furthermore, when the news reached London, any lingering hopes of European recognition of the Confederacy were finally abandoned. Henry Adams, whose father was serving as the U.S ambassador to the United Kingdom at the time, wrote, "The disasters of the rebels are unredeemed by even any hope of success. It is now conceded that all idea of intervention is at an end."
