One of the strangest parts of the history of the British Empire involves that commercial venture generally known as the East India Company, though its original name when founded by royal charter on the very last day of 1600 was the <em>Governor and Company of Merchants of London Trading into the East Indies</em><span>. </span>
The right answer is iron.
Let me explain: During the Civil War, the Confederacy wanted to acquire modern armored ships, therefore, gaining advantage over their adversaries. Somewhere around 1861, the Confederate Congress purchased ships called 'ironclads' from overseas, and a few moths later, they started working on constructing and converting their wooden ships to ironclads, by coating the sides of their ships with iron.
The goal behind this new defense strategy was to make it more difficult for heavy artillery to pierce the ships, thus gaining a new naval advantage over the enemy.
I hope this answer helps! Have a great week :)
