Analysis of information sources in references of the Wikipedia article "USS Pennsylvania (1837)" in English language version.
Consider the Navy's ship-of-the-line program that followed the War of 1812… Congress, on April 29, 1816, 'authorized to cause to be built, nine ships to rate not less than 74 guns each'. All nine were eventually laid down, in shipyards from Portsmouth, New Hampshire, to Norfolk, Virginia, and four of them were completed in a timely manner by the end of 1820. None of these ships ever saw action, of course, for the world had entered an extended era of peace.
The Government vessels had been scuttled in the afternoon before the Pawnee arrived, to prevent their being seized by the Secessionists … The following are the names of the vessels which were destroyed: Pennsylvania, 74 gun-ship; steam-frigate Merrimac, 44 guns; sloop-of-war Germantown, 22 guns; sloop Plymouth, 22 guns; frigate Raritan, 45 guns; frigate Columbia, 44 guns; Delaware, 74 gun-ship; Columbus, 74 gun-ship; United States, in ordinary; brig Dolphin, 8 guns; and the powder-boat … [plus] line-of-battle ship New-York, on the stocks … Large quantities of provisions, cordage and machinery were also destroyed — besides buildings of great value — but it is not positively known that the [dry] dock was blown up.
