Civil War generals were military leaders who played crucial roles during the American Civil War from 1861 to 1865. They commanded armies for both the Union and the Confederacy, making strategic decisions that influenced the outcome of battles. Notable generals included Ulysses S. Grant for the Union and Robert E. Lee for the Confederacy, each known for their unique tactics and leadership styles. These generals often faced significant challenges, including limited resources, diverse troop morale, and the complexities of warfare. Their decisions shaped key battles such as Gettysburg and Antietam, which were pivotal in determining the war's direction and ultimately its conclusion.
