A SLOOP OF WAR.
The ships of war in those earlier times were wooden sailing vessels, and they were very slow-goers when compared with the swift cruisers which sail the ocean now. The largest of these vessels were called ships of the line, because they formed the line of battle in any general fight at sea. They usually had three decks, with guns on every deck. The upper deck was often covered over, and on the open deck thus formed above there was a fourth tier of guns. This open deck was called the forecastle and quarter-deck. Some of the largest ships of the line carried as many as 120 guns each; the smallest was built to carry 72 guns.
Next in size to these ships were the frigates. A frigate had only one covered deck and the open forecastle and quarter-deck above it, and therefore had but two tiers of guns. The largest frigate carried sixty guns, besides a large pivot gun at the bow. The American frigates were noted for their speed.
Still smaller than the frigates were the corvettes, or sloops of war, as they are more commonly called. These had but one tier of guns, and that was on the open deck. They were rigged like the larger vessels, with three masts and square sails.
THE STEAM FRIGATE POWHATAN.
The fourth class of vessels included the brigs of war, which had but two masts and carried from six to twenty guns. Equal to them in size were the schooners, which also had two masts, but were rigged fore-and-aft. The guns which they carried were commonly much smaller than those on the sloops and frigates.
After Robert Fulton's invention of the steamboat in 1807 there were many attempts to apply steam on vessels of war. But it was a long time before these attempts were very successful. The earliest war steamships were driven by paddle-wheels, placed at the sides of the vessels. The paddles, besides taking up much valuable space, were exposed to the shots of the enemy, and in any battle were very easily crippled and made useless. But the speed of these vessels was much greater than that of any sailing ship, and this alone made them very desirable. For many years steam frigates were the most formidable vessels in the navy. The first successful steamship of war was the English frigate Penelope, which was built in 1843, and carried forty-six guns. One of the earliest and most noted American vessels of the same type was the Powhatan. The first screw line of battle ship was built by the French in 1849. It was called the Napoleon, and carried one hundred guns. It was so successful that steamships soon began to take the place of sailing vessels in all the navies of the world.
