In late 1861 , the United Kingdom gets involved in the Southern rebellion on the side of the Confederacy in the wake of the Trent Affair . At the start of 1862 , the Union attempts to win a decisive victory against the Confederacy before British reinforcements arrive in the Americas at the Battle of Culpeper , but fail miserably due to the awful leadership of George B. McClellan . But after numerous defeats for the Anglo-Confederate Alliance , losing Robert E. Lee and most of Canada , the United Kingdom accepts an offer of peace from the Union on the Union 's terms . Britain frames the Confederacy for supposedly causing the Trent Affair and switches sides in the war . As a result , in early 1863 the Confederacy admits defeat , ending the conflict two years sooner . John Wilkes Booth is arrested and sentenced to death for trying to help Confederate snipers kill President Abraham Lincoln , therefore Lincoln is never assassinated
