American Civil War

1861–1865

The first battle between ironclads, at Hampton Roads, made every wooden navy in the world obsolete overnight. The Union used its fleets to blockade the South and force its way past the forts guarding New Orleans and Mobile Bay, while Confederate raiders such as Alabama hunted Union merchant ships across the oceans.
