Thanks so much for that link! The pictures were terrific. I guess I'm in a bitchy, contentious mood today, though, as I have some issues with the narrative that went with it. I'll vent below. Just don't take it personally; I'm directing my annoyance at the writer, not you.
This is truly nonsense. This writer assumes that ships actively sought out battles with ONLY their own kind of ship, and that simply isn't true. The history of these wars is replete with examples of ships of the line capturing frigates, sloops, brigs, etc. The Royal Navy would hardly have kept the 64s in service just in case they should encounter one of their French counterparts.
This is even more ridiculous. Navies of the Western World settled on the 74 gun two-decked design because it was deemed to be optimal. That did not mean that a 64 gun ship could not and did not engage 74 gun ships of the line. They were not that much less powerful, and you will find, in many of the major battles of this era, that a 64 gun ship of the line tackled a 74 (Think Agamemnon and Ca Ira). A Royal Navy captain who was in command of a 64, and evaded action with a French or Spanish 74, would have found himself court martialed, IMHO.
Contained in this largely incomprehensible paragraph is the reason that the Admiralty razeed the ships. It was more economical to operate a powerful frigate (with 300 men) than a ship of the line (with 600), if the extra firepower of the ship of the line wasn't needed.
This is the most absurd paragraph at all. This was war, it was not a game, and while codes of honor were important, that did not preclude a larger ship from capturing a smaller ship. Sure, the dream of every captain was to fight a battle with his opponent of equal strength, ship to ship, but that didn't mean it happened all that often. There were almost always some size discrepancies. And if this idiot's theory is true, then how terribly unchivalrous for a squadron to capture a single ship.
I think that perhaps the writer is confusing general operations and conventions with those in force during a fleet action, in which case certain rules did theoretically apply. As we saw at St. Vincent and the Nile, frigates were supposed to be left alone unless they initiated combat.
