What happened because of the Ironclad
The Confederates were finally winning the war of the sea. then the Union decides their wooden ships are not enough to defeat the ironclad. So they fought fire with fire and made their own ironclad. The Union had lots of supplies so they can make lots of ironclads. But the Confederates had limited supplies so they could only make a few ironclads. So soon the Confederates lost their ironclads and the Union had new technology to use.
