One of the most notable features of the Antietam battlefield was the river crossings.

The Antietam Creek played a crucial role in the battle's dynamics, influencing troop movements and strategies for both the Union and Confederate forces. Key locations, such as the Burnside Bridge, became focal points of intense fighting, as control of these crossings was essential for advancing troops and securing supply lines. The terrain surrounding the creek, including the challenges of navigating the bridges and fords, significantly impacted the flow of the battle and the decisions made by commanders.
