February 16, 1862 - Union General Ulysses S. Grant's army captured Fort Donelson on the Cumberland River. This victory gave the Union control of northern Tennessee and paved the way for the occupation of Nashville and earned Grant the nickname "Unconditional Surrender."
Brigadier General, Simon Buckner, CSA, happened to be a former classmate and friend of Grant’s.

Confederate General Buckner was the only commander to stay in Fort Donelson and share the soldiers’ fate; the other commanders fled. Perhaps Buckner hoped to benefit from their friendship when he asked Grant for terms of surrender. Grant replied, “No terms except unconditional and immediate surrender can be accepted. I propose to move immediately upon your works.” The two generals met at Dover Hotel, where Buckner surrendered troops and supplies. Grant had captured the most prisoners ever taken in an American war. Someone decided U.S. in Grant’s name stood for “unconditional surrender.”
When General Lew Wallace reached the hotel for the surrender, he gave orders against gloating. “Move the line forward, take possession of persons and property, but not a word of taunt—no cheering.”
