Answer:
The correct answer is B, as the statement is false. The Battle of Antietam was a victory for the Union.
Step-by-step explanation:
The Battle of Antietam was fought on September 17, 1862 at Sharpsburg, Maryland, as part of the Maryland Campaign.
It was one of the most important battles of the Civil War on the territory controlled by the Union, with 23,000 victims. Although not conclusive from a tactical point of view, it had a significant meaning, being regarded with some generosity by the Unionists as a "partial" victory for them and for having provided President Abraham Lincoln with the right to issue his well-known Emancipation Proclamation.
