150 years on

Today is the 150th anniversary of the Battle of Antietam, where more than 2100 Union soldiers lost their lives ending Lee's invasion of Maryland. It was more or less a tactical draw (though Lee fled the field) largely because McClellan failed to commit a full 3rd of his forces and would not pursue a retreating enemy (costing him his job). However, it was and remains a significant strategic victory for the Union, allowing Lincoln the means to issue the Emancipation Proclamation and preventing England and France from recognizing the Confederacy. To those who lost their lives on that day near Sharpsburg, thank you. RIP.
