It was the greatest coffee run in American history. The Ohio boys had been fighting since morning, trapped in the raging battle of Antietam, in September 1862.

The men held out tin cups, gulped the brew and started firing again. “It was like putting a new regiment in the fight,” their officer recalled. Three decades later, McKinley ran for president in part on this singular act of caffeinated heroism. -The New York Times.
