Why did civil war battles occur near railroads and waterways?

Civil War battles often occurred near railroads and waterways because these transportation routes were vital for moving troops, supplies, and equipment. Control of railroads allowed armies to quickly reinforce their positions and maintain supply lines, while waterways provided essential routes for transporting goods and troops. Additionally, battles near these strategic locations could disrupt the enemy's logistics and communication, making them critical points of conflict. Thus, the geography of railroads and waterways significantly influenced military strategies and battle locations during the war.
