What was the union military strategy of divide and conquer?

The Union military strategy of "divide and conquer" aimed to weaken the Confederate forces by separating them into smaller, manageable groups, making them easier to defeat. This approach involved disrupting supply lines, capturing key territory, and isolating Confederate armies from one another. By dividing their resources and forces, the Union sought to diminish the overall effectiveness of the Confederacy, ultimately leading to a more decisive victory. This strategy was exemplified in campaigns like General William Tecumseh Sherman's "March to the Sea."
