Chancellorsvillie

Explanation:

The first union victory of the civil war came at Antietam

Explanation:

The Antietam battle was full of weapons that were available at the state during that time. Most of the weapons were employed to help in the contribution of increased death troll and the terrain. It was also an instrument factor in reducing the gap that existed in the battlegrounds.

The union was also in desperate need of the victory in Antietam, which was solely for the union during that time. The Antietam battle was inclusive, but the emancipation proclamation was read effectively after the end of slavery.
