The illustrated Union river force combines mortar barges for siege bombardment with armored paddle steamers preparing to rush defenses. Concentrating that force required iron, manufactured equipment, and transport connections. The Confederacy possessed some resources on paper, yet shortages of processed material and disconnected infrastructure prevented it from using them together effectively. The Union had enough east-west connections to bring its resources to bear, although the margin was described as limited. The comparison explains why the ability to move manufactured goods mattered to river warfare.
