I was perusing this thread and I came across Stalker's comments on Operation Bagration... I know Brian's original post desired discussion to revolve around ancient times, but I think this is very interesting.
1. Byelorussian assault operation (Bagration) planned by Konstantin Rokossovsky (june, 1944). The result of operation. The defending army (Wehrmacht) during summer battles lost (KIA, wounded and POWs) over 900,000 men. The attacking army (Red Army) for the same period lost about 100,000 men. Group of armies "Center" was simply annihilated, Group of Armies "North" found itself "locked" in Baltic peninsula. Isn't that the gratest victory ever. Even in 1941 the victorious Wehrmach blowing army after army in the East Front, having POWs whose numbers were hundreds thousands (!!!) was anable to achieve such a score!
Just last week, a friend of mine came back from a tour in Afghanistan. As we were talking culture and history, he mentioned Operation Bagration. Since I was unfamiliar with it, I had to look it up.
Stakler is right, the numbers are mind boggling. During a two month offensive, the Russians finally successfully employed maskirovka, mobility, and manpower to give the Germans their worst defeat.
But here's the kicker... the Wehrmacht did not crumble and surrender. The Russians still had to earn every mile on the way to Berlin. Could any other army have survived a defeat that catastrophic? Back in 1917, the Russians themselves mutinied rather than continue a bad war. I'm shocked the Wehrmacht never mutinied.
It is reminiscent of Cannae. But do we remember that Cannae (Summer 216 BC) happened after Trebia (December 218 BC) and Lake Trasimene (Summer 217 BC)? At Trebia, Hannibal inflicted over 20,000 casualties on a Roman army of 40,000. And at Lake Trasimene, the Romans lost over 75% of their 40,000 strong army. In both battles, the Carthaginian's losses were few. How did the Romans carry on? Throughout history the conventional wisdom is to sue for peace after military disasters.
Once again, I'll state that I'm not trained in history nor military strategy... I'm just an ethusiast.
