When were steamships first used in a war?

• A. 1776
• B. 18 to 22
• C. 1840s
• D. 1900

Answer: (B)

Steam power first entered naval warfare as engines became reliable enough to drive ships in combat, not just for towing or demonstration. The pivotal shift happened in the late 1810s into the early 1820s, when steam-powered ships began to see actual combat use and note-worthy operations at sea. This early window marks the first wartime deployments of steam-driven warships, well before steam navies became common in the mid-19th century and long before the 1900 era. The other dates either precede steam-powered ships, or come after the era when steam warfare was already established, making them less accurate for the first wartime use.
