Nope, I’m not. There’s a difference between purpose and maximum use, and what things actually end up doing. Consider a modern air force, which in proportion of expense and organization is not terrifically different from a medieval heavy cavalry company. You’ve got the pilot and his plane, just like a rider and his horse. And behind that pilot, a dozen other people, mechanics and ordnance loaders, all of whom are necessary to allow that man to go out and kick ass. And also, he costs an effing fortune. For what his operation costs you, you could fill a ship with infantry.
So why do you have him? So he can go fly around and luck into a dogfight, and shoot up another plane? No. He might do that, and that’s great. But you’ll get optimal return for the investment when he takes out a bridge, or strafes a destroyer. Or takes out an entire tank column. Now you’ve justified the trouble and expense of that arrangement. Because two dozen guys and a sack full of cash just caused an amount of damage to the enemy far exceeding the expense of their employment. Victory in the entire war, which is the point, will follow if that pattern continues. Now of course, your opponent will get his own air force, and you’ll develop interception tactics, and blah blah. But the original point of the air force, and its continuing optimum use, is to attack ground targets.
Cavalry did run around ancient battlefields and smack into each other, but that wasn’t the point…it was the point being frustrated. Optimal use of heavy cavalry was to assault infantry. Suboptimal was to chase and suppress routing forces. Worst of all was to become engaged, and fail to immediately rout, enemy cavalry. Because now 80% of your expenses are over on your flank grinding on the other guy’s 80% of expenses and no one is getting their money’s worth.
What Malthus is suggesting, or rather just repeating Keegan’s tired and erroneous conclusion, is tantamount to suggesting that the last century of air combat has been nothing more than exaggerated bluffing, because surface-to-air technology keeps planes from being effective v. ground targets, and so planes never attack ground targets. Ridiculous on its face, and even if it were not, the steady evolution of combat planes belies the notion. They are effective. We keep building more of them, and more advanced models, because they work. 400 years of heavy cavalry evolution should tell you the same. Heavy cavalry development proceeded aggressively, polearms evolved in response, back and forth. This cannot occur without pressure to change and incentive to innovate, such pressure and incentive derived from men on horses slamming into men carrying spears, then both sides examining the results and changing things up.
This process never occurs if every time 100 peasants hold spears in a bunch, horsies just turn around and canter off into the sunset.
