Why was Robert e Lee so important during the civil war. What did he do. Short paragraph please!

Robert E. Lee was the head of the Confederate army during the Civil War between 1861 and 1865. Although he was not in favor of slavery, and even President Lincoln had offered him command of the Union army, Lee decided to remain loyal to his native state, Virginia, and join the Confederate cause, leading the southern forces, which were worse composed than those of the north, to fight on all fronts and put the Union army in trouble.
