The largest sloops were also frigate-built, carrying twenty-two 32-pound carronades on the main-deck, and twelve lighter guns on the quarter-deck and forecastle, with a crew of 180. The large flush-decked ship-sloops carried 21 or 23 guns, with a crew of 140 men. But our vessels most often came in contact with the British 18-gun brig-sloop; this was a tubby craft, heavier than any of our brigs, being about the size of the Hornet. The crew consisted of from 110 to 135 men; ordinarily each was armed with sixteen 32-pound carronades, two long 6's, and a shifting 12-pound carronade; often with a light long gun as a stern-chaser, making 20 in all. The Reindeer and Peacock had only 24-pound carronades; the Epervier had but eighteen guns, all carronades. 39
Among the stock accusations against our navy of 1812, were, and are, statements that our vessels were rated at less than their real force, and in particular that our large frigates were "disguised line-of-battle ships." As regards the ratings, most vessels of that time carried more guns than they rated; the disparity was less in the French than in either the British or American navies. Our 38-gun frigates carried 48 guns, the exact number the British 38's possessed. The worst case of underrating in our navy was the Essex, which rated 32, and carried 46 guns, so that her real was 44 per cent, in excess of her nominal force; but this was not as bad as the British sloop Cyane, which was rated a 20 or 22, and carried 34 guns, so that she had either 55 or 70 per cent, greater real than nominal force. At the beginning of the war we owned two 18-gun ship-sloops, one mounting 18 and the other 20 guns; the 18-gun brig-sloops they captured mounted each 19 guns, so the average was the same. Later we built sloops that rated 18 and mounted 22 guns, but when one was captured it was also put down in the British navy list as an 18-gun ship-sloop. During all the combats of the war there were but four vessels that carried as few guns as they rated. Two were British, the Epervier and Levant, and two American, the Wasp and Adams. One navy was certainly as deceptive as another, as far as underrating went.
The force of the statement that our large frigates were disguised line-of-battle ships, of course depends entirely upon what the words "frigate" and "line-of-battle ship" mean. When on the 10th of August, 1653, De Ruyter saved a great convoy by beating off Sir George Ayscough's fleet of 38 sail, the largest of the Dutch admiral's "33 sail of the line" carried but 30 guns and 150 men, and his own flag-ship but 28 guns and 134 men. 40 The Dutch book from which this statement is taken speaks indifferently of frigates of 18, 40, and 58 guns. Toward the end of the eighteenth century the terms had crystallized. Frigate then meant a so-called single-decked ship; it in reality possessed two decks, the main- or gun-deck, and the upper one, which had no name at all, until our sailors christened it spar-deck. The gun-deck possessed a complete battery, and the spar-deck an interrupted one, mounting guns on the forecastle and quarter-deck. At that time all "two-decked" or "three-decked" (in reality three- and four-decked) ships were liners. But in 1812 this had changed somewhat; as the various nations built more and more powerful vessels, the lower rates of the different divisions were dropped. Thus the British ship Cyane, captured by the Constitution, was in reality a small frigate, with a main-deck battery of 22 guns, and 12 guns on the spar-deck; a few years before she would have been called a 24-gun frigate, but she then ranked merely as a 22-gun sloop. Similarly the 50- and 64-gun ships that had fought in the line at the Doggerbank, Camperdown, and even at Aboukir, were now no longer deemed fit for the purpose, and the 74 was the lowest line-of-battle ship.
The Constitution, President, and States must then be compared with the existing European vessels that were classed as frigates. The French in 1812 had no 24-pounder frigates, for the very good reason that they had all fallen victims to the English 18-pounder's; but in July of that year a Danish frigate, the Nayaden, which carried long 24's, was destroyed by the English ship Dictator, 64.
The British frigates were of several rates. The lowest rated 32, carrying in all 40 guns, 26 long 12's on the main-deck and 14 24-pound carronades on the spar-deck—a broadside of 324 pounds. 41 The 36-gun frigates, like the Phoebe, carried 46 guns, 26 long 18's on the gun-deck and 32-pound carronades above. The 38-gun frigates, like the Macedonian, carried 48 or 49 guns, long 18's below and 32-pound carronades above. The 32-gun frigates, then, presented in broadside 13 long 12's below and 7 24-pound carronades above; the 38-gun frigates, 14 long 18's below and 10 32-pound carronades above; so that a 44-gun frigate would naturally present 15 long 24's and 12 42-pound carronades above, as the United States did at first. The rate was perfectly proper, for French, British, and Danes already possessed 24-pounder frigates; and there was really less disparity between the force and rate of a 44 that carried 54 guns than there was in a 38 that carried 49, or, like the Shannon, 52. Nor was this all. Two of our three victories were won by the Constitution, which only carried 32-pound carronades, and once 54 and once 52 guns; and as two thirds of the work was thus done by this vessel, I shall now compare her with the largest British frigates. Her broadside force consisted of 15 long 24's on the main-deck, and on the spar-deck one long 24, and in one case 10, in the other 11 32-pound carronades—a broadside of 704 or 736 pounds. 42 There was then in the British navy the Acasta, 40, carrying in broadside 15 long 18's and 11 32-pound carronades; when the spar-deck batteries are equal, the addition of 90 pounds to the main-deck broadside (which is all the superiority of the Constitution over the Acasta) is certainly not enough to make the distinction between a frigate and a disguised 74. But not considering the Acasta, there were in the British navy three 24-pounder frigates, the Cornwallis, Indefatigable, and Endymion. We only came in contact with the latter in 1815, when the Constitution had but 52 guns. The Endymion then had an armament of 28 long 24's, 2 long 18's, and 20 32-pound carronades, making a broadside of 674 pounds, 43 or including a shifting 24-pound carronade, of 698 pounds—just six pounds, or 1 per cent, less than the force of that "disguised line-of-battle ship" the Constitution! As the Endymion only rated as a 40, and the Constitution as a 44, it was in reality the former and not the latter which was underrated. I have taken the Constitution, because the British had more to do with her than they did with our other two 44's taken together. The latter were both of heavier metal than the Constitution, carrying 42-pound carronades. In 1812 the United States carried her full 54 guns, throwing a broadside of 846 pounds; when captured, the President carried 53, having substituted a 24-pound carronade for two of her 42's, and her broadside amounted to 828 pounds, or 16 per cent nominal, and, on account of the short weight of her shot, 9 per cent, real excess over the Endymion. If this difference made her a line-of-battle ship, then the Endymion was doubly a line-of-battle ship compared to the Congress or Constellation. Moreover, the American commanders found their 42-pound carronades too heavy; as I have said the Constitution only mounted 32's, and the United States landed 6 of her guns. When, in 1813, she attempted to break the blockade, she carried but 48 guns, throwing a broadside of 720 pounds—just 3 per cent more than the Endymion. 44 If our frigates were line-of-battle ships the disguise was certainly marvellously complete, and they had a number of companions equally disguised in the British ranks.
The 44's were thus true frigates, with one complete battery of long guns and one interrupted one of carronades. That they were better than any other frigates was highly creditable to our ingenuity and national skill. We cannot, perhaps, lay claim to the invention and first use of the heavy frigate, for 24-pounder frigates were already in the service of at least three nations, and the French 36-pound carronnade, in use on their spar-decks, threw a heavier ball than our 42-pounder. But we had enlarged and perfected the heavy frigate, and were the first nation that ever used it effectively. The French Forte and the Danish Nayaden shared the fate of ships carrying guns of lighter calibre; and the British 24-pounders, like the Endymion, had never accomplished any thing. Hitherto there had been a strong feeling, especially in England, that an 18-pound gun was as effective as a 24- in arming a frigate; we made a complete revolution in this respect. England had been building only 18-pounder vessels when she ought to have been building 24-pounders. It was greatly to our credit that our average frigate was superior to the average British frigate; exactly as it was to our discredit that the Essex was so ineffectively armed. Captain Porter owed his defeat chiefly to his ineffective guns, but also to having lost his topmast, to the weather being
