Final answer:
Robert E. Lee served the Confederacy, was a skilled strategist, and came from the South; Ulysses S. Grant served the Union, used his numerical and resource advantage, and was from the North. The correct answer to how they differed is 'D. Lee was from the North and Grant was from the South.'
Step-by-step explanation:
Robert E. Lee and Ulysses S. Grant differed in several ways during their military careers in the American Civil War. Robert E. Lee was a skilled strategist known for his ability to win battles against larger Union forces, as seen in the Battle of Chancellorsville. He hoped that his success would lead to foreign support and a negotiated peace. Lee served the Confederacy and was born in the South.
Ulysses S. Grant, on the other hand, was noted for his relentless pursuit of victory and willingness to sustain heavy casualties to achieve his objectives, which became evident during campaigns such as Vicksburg and the prolonged struggles in Virginia. Grant used the significant advantage of the Union’s more considerable numbers and resources, understanding that while the Union could replace its forces, the Confederate forces, with their smaller population, could not sustain such losses indefinitely. Grant served the Union and hailed from the North.
The correct answer to the question is, therefore, 'D. Lee was from the North and Grant was from the South.'
