Churchill, Winston S. "If Lee had not Won the Battle of Gettysburg"
Divergence: 1863 CE
What if: Jeb Stuart reached the battlefield in time to support Pickett's charge. Later, Lee unilaterally freed the slaves and Britain recognized the CSA.
Summary: Musings on how a Confederate defeat at Gettysburg might have prevented the formation of the English-speaking union. Thus, the story could be said to be recursive alternative history.
Comments: A discussion of the credibility of the divergence is found in Hook's The Hero in History, q.v.
