I just need a quick reference was Lee on the union forces or the confederate. I always confuse him and grant.
Ok i got it now.
It seems like you have already found the answer, but I'll still explain how to differentiate between General Robert E. Lee and General Ulysses S. Grant.
During the American Civil War, Robert E. Lee served as a general in the Confederate Army. On the other hand, Ulysses S. Grant served as a general in the Union Army. To remember this distinction, you can associate "Lee" with the "Confederate" side, as both words start with the letter "C." Likewise, you can associate "Grant" with the "Union" side, as both words start with the letter "U." This simple mnemonic can help you quickly recall their affiliations within the context of the Civil War.
