My PBEM opponent decided he really, really wanted to keep a hex adjacent to where I had an entire 3 division korp of Germans stacked. The hex would have outflanked his Fortress hexes and given a panzer korp an avenue to attack, so I can see him wanting to keep it.
Anyways, he put at least 300 stacking points of stuff in the hex.
SO I bombed it...probably killed about 500 men, but disrupted only a bit of every unit.
I then hit it with about 75 stacking points of artillery, some of which affected with bonus from cards. (freedom from Manstein).
Probably killed about 1000 men. And disrupted a bit of every unit.
Then I attack. With about 100 stacking points. I inflict massive casualties (losing about 500 men)....probably around 140 strength points. But fail to take the hex. So I attack again with another 100 strength points. I take about 300 casualties as I inflict about 100 strength points worth of losses. But the hex holds due to a single strength point of armour, and an artillery unit.
I suspect that the first attack lowers readiness. And morale. So if you attack it again, you may suffer less casualties because the enemies readiness drop (but a little more due to overstacking), but inflict more because of his morale drop.
Come the next turn, there would be no way he could hold it with those same units. As it was, he moved two fresh divisions in from reinforcements, and played a fortification card....so he did get to keep the hex.
