This is a thread that recently started on alt.war. Naturally, my contribution 
dealt with the Civil War, so I thought I'd cross-post.

I'd like to mention the Battle of Antietam in the American Civil War, September
17, 1862. This battle, though one of the bloodiest, was far from decisive in
the military sense (it was essentially a draw) but was very decisive on the
course of subsequent history due to the following political circumstances:

1) The British Foreign Secretary, Lord Russell, had urged the Prime Minister,
Lord Palmerston, that the time was right for France and England to intervene in
the war in favor of separation. Palmerston agreed, pending a favorable (for the
Confederacy) outcome of the on-going military campaign (Antietam).

2) Lincoln had decided the only way to avoid European intervention (on the side
of the South) was to explicitly state that the North was fighting to end
slavery. He made this decision in July 1862, but was waiting for a military
victory to announce it (the Emancipation Proclamation) so it would not appear
to be a move of desperation.

The nominal victory by the North at Antietam gave Lincoln the opportunity he
needed. He issued the Emancipation Proclamation within days of the battle.
After that, it was politically impossible for England to explicitly support the
Confederacy, since the English people were strongly opposed to slavery.
The Confederacy's prospects of achieving independence without outside support
were never very bright. Eventually the Union was preserved.

Had the North lost yet another battle, the machinery for English and French
intervention would likely have begun to roll. It is doubtful that the
Emancipation Proclamation (issued after a string of military defeats and with
the European powers acting to impose peace) would have had enough credibility
to reverse the process. It is likely that the combined interests of England and
France would have ended the war in favor of the South (as Spain and France had
ended the American War for Independence in favor of the colonies). Subsequent
world history, with a fragmented United States, is a matter of speculation, but
it is fair to say it would have been altered significantly.

The fascinating bit of trivia connected with the battle of Antietam, is that it
is unlikely that the Union Army would have trapped Lee's Army at Sharpsburg in
the first place had not a private in an Indiana infantry regiment, B. Mitchell,
found a copy of Lee's orders (wrapped around some cigars) near Lee's abandoned
headquarters at Frederick.
