I'm missing something about fighting in the colonies, particularly Viet Nam.
As France, I declared a protectorate over Hanoi and Tonkin troops starting fighting me. They retreated to Langson and sat there for a while (and I had to deal with a buggy unit that couldn't be fought and couldn't retreat, but that's another thread).
It's a stack with a total combat value of 232. They have artillery (8 guns I think) but no firearms.
I attacked it with a colonial infantry brigade, an infantry brigade, a light cavalry brigade, and some native units under a 1 star general (so not much help). The total stack combat value was over 500, but lost tons of cohesion on its way.
It was slaughtered. I barely made it out alive fighting this unarmed rabble.
So I built a ton more units. Thinking that cohesion was the problem (and the fact it takes 40+ days to move from Hanoi to Langson), I tried a marine attack. I hit it with 2 marine divisions and a marine brigade. Again, the battle wasn't even competitive. I was slaughtered.
Mystified, I gave up in disgust, cursing this game's unpolished state.
But Tonkin wasn't done. They attacked me in Caobang. Their stack suffered little cohesion damage as it moved from Langson and defeated two entrench colonial infantry brigades (combat value over 300). The battle was kind of close, but not that close.
I took advantage of their attack, however, to take Langon by landing, putting an entire infantry corps ashore. But I'm afraid to attack Caobang even with this massive force because Tonkin simply seems invincible in battle.
So what's happening here? How are these guys able to fight off modern French units with such ease (and without rifles of any kind)? What's the trick to fighting in Viet Nam or the colonies in general?
