Factual error: After the Fort Sumter battle, Mary Todd sees the newspaper on Lincoln's desk which states "20,000 soldiers dead", and what appears to be an April 1861 date (which makes sense since that's when the Battle of Fort Sumter took place.) However, there were zero causalities at that battle. And the first major battle, First Battle of Bull Run in late 1861, didn't even see 1,000 causalities.

Continuity mistake: When Abraham Lincoln picks up the pocket watch left in Willie's room, he opens it, but in the next shot it's closed.

Factual error: At the start of the war, it says Fort Sumter 1861. However, on the battlefield we see the US flag with 35 stars. In April 1861, there were only 33 states.
