Question

What up and coming Union general told the Confederates at Fort Donelson that no terms except for immediate and unconditional surrender could be accepted? What was his nickname after this surrender?​

Answer 1

General Ulysses S. Grant.

His nickname after this surrender was "Unconditional Surrender Grant".

Step-by-step explanation:

Brid. General Ulysses S. Grant was the Commanding General of the Union Army during the American Civil War. He would also become famous for his ability to 'enforce' the surrender of three enemy armies and become the 18th President of the United States.

Ulysses S. Grant was famous for his "unconditional and immediate surrender" of the Confederate Army during the Civil war which was the first major victory of the Unions during the civil war. Moreover, his ultimatum to the Confederates would become a frequent act of negotiation by leaders in the future.

He was later given the nickname "Unconditional Surrender Grant", a play based on his initials "U. S. G/ Ulysses S. Grant".
