In Their Quiet Fields: Antietam video 1

About In their Quiet fields, from BoardGameGeek:

In their Quiet fields is a Tactical level board-wargame of America's bloodiest single day. It is meant to be played by two or more players. It is hoped that the game accurately portrays the desperate struggle that occurred on September 17, 1862 between the Armies of the Potomac and of Northern Virginia. At odds of 1:2 or worse, Lee's Army of Northern Virginia was narrowly able to avert disaster. This game shows that victory is within the grasp of both armies and that final victory may not be decided until the very end.
