Answer:
They were both generals who fought on opposite sides during the American Civil War. General Sherman was a Union Army general, while General Hood was a Confederate Army general.
Step-by-step explanation:
During the Civil War, General Hood served under General Robert E. Lee and participated in several major battles, including the Battle of Antietam, the Battle of Gettysburg, and the Battle of Chickamauga. General Sherman, on the other hand, was known for his successful campaigns in the Western Theater of the war, including his famous march to the sea.
The letter you referred to was written by General Sherman to General Hood in 1864, during the Atlanta Campaign of the Civil War. In the letter, Sherman offered Hood the opportunity to evacuate the civilian population of Atlanta before the Union Army took control of the city. Hood refused the offer, and the Union Army ultimately captured Atlanta and forced the Confederate Army to retreat.
Overall, the military connection between General Sherman and General Hood was that they were both important figures on opposing sides during one of the most significant conflicts in American history.
