When last we left the Army of Northern Virginia, General
Robert E. Lee was leading it away from the victory
at Manassas and taking the war into Union territory for the first time. (He
did this for both strategic military and logistical reasons: he was literally
looking for food supplies for his men.) It was a bold move and one of the few
times the north actually felt the direct burden of fighting.
Try to imagine the feelings in Washington: enemy
forces showing all signs of encircling the city, cutting off its lines of
communications with the rest of the Union. The fear was palpable, and the
Radical Republicans…well, the phrase “wound up tighter than a cheap watch”
comes to mind.
Following Manassas, President Lincoln felt the only
general able to counter Lee was McClellan (which speaks more about the lousy
quality of the available commander pool than it does about McClellan’s
capabilities), so the expert at procrastination was hauled up from the Peninsula and installed at the head of the Army of the Potomac again.
McClellan was handed an extraordinary gift in the
form of the discovery on 13 September of Lee’s strategic plan (found wrapped
around three cigars). By speedily deploying his troops (which outnumbered the
Confederates 75,000 to 55,000) while Lee’s army was widely dispersed, he might
have turned the tables. But, being McClellan, he waited 18 hours to take
action.
The two forces finally met 150 years today on
farmers’ fields near the Maryland town of Sharpsburg. Through rows of man-high
ripened corn, across Antietam Creek and along a sunken road that became known
as Bloody Lane, they slogged it out through most of the day.
It was the bloodiest battle in US history; 23,000 casualties
from both sides. More than 2100 Federals and 1500 rebels died.
Lee went all-in, McClellan never committed more than
75% of his force, and they fought to a standstill. The next day, Lee at first
waited for McClellan to attack, but “the young Napoleon”…just sat there. The
Army of Northern Virginia withdrew without being pursued.
After a month of McClellan’s inactivity, Lincoln
finally removed him from command permanently. He also took advantage of the
tactical win to issue the Emancipation Proclamation the following week.
Sharpsburg was a geopolitical turning point;
European powers (in particular, Britain & France) decided there was no
advantage in backing the Confederacy by diplomatic recognition, so it was
essentially on its own. And; it never had either the agricultural or
industrial resources to stand alone against the United States.
But the war would slog on for another two and a
half years.
