With Grant and Foote's capture of Fort Donelson, the lynchpin that held the chain of Confederate defenses in the west collasped. Bowling Green, Kentucky was abandoned. While not the commander of the captured Confederate forces, Gen. Simon Buckner was left to surrender the command. He had helped Grant out before the war when Grant was broke. Buckner was surprised when Grant offered Buckner no terms, no honors of war.
"Though Grant treated Gen. Buckner with characteristic manliness, there were not wanting smart fellows among his officers who could not profit by their cheif's example. As Buckner, with his faithful staff, stepped on the board the boat that was to convey them northward, one of his regiments raised a thrilling cheer, when a Federal band, apparently in derision, struck up Yankee Doodle. An officer afterward asked Buckner in Grant's presence, and in a very sarcastic tone, whether the national air did not revive in his mind some pleasant associations of the past. "Yes, Colonel," he replied, "but it also reminds me of an incident which occurred a few days ago in our camp. A soldier was being drummed out of one of the regiments for a serious offense. The musicians were playing the Rogue's March. 'Stop,' cried the fellow, you have mistaken the tune. Play Yankee Doodle; a half million of rogues march to that every day.'"
If you have a chance, visit Fort Donelson National Battlefield Park. It is well preserved and the site of some early sharpshooting in the Western Theatre.
