Thanks for your comments.
Regarding 1, I'm positive though I didn't know about elements vs units and it may be possible that in some cases I had two corps in same region with 2 wagons and thus totalling 8 elements. but still, the wagon doesn't disapear. and I recall having just one wagon unit with X elements in it (<4), alone in a regions and creating a depot.
Regarding 2- : yes, I knew about the order, but that's when you know what you want to do. So how do you order a unit to destroy the depot post-combat as you retreat. The IA does that for Russians. basically you want to hold the city and its depot, but on the other hand if you lose the battle, retreat and destroy the depot (terre brulée)? It's a conditional order.
Again 2- : agree with the city providing supply. that was what I thought, but then why do my units suffer loss of supply (I measured it every turn)? Options:
- the city has no supply capacity (below level 3 I believe)
- the city is not connected to Home supply centres (Warsaw for 1812) because too far or route cut by enemy-owned region?
- the city does not produce enough for the present units? how do you check that?
- the units are not inside the city but in its region
see, I have my interrogations...
Oh, i understand the destroy depot question now
Yes, in fact, besides you giving the orders, your units or the enemy ones can destroy them automatically during the battle or retreat because of the scorched earth rule.
You have no control over it. Its something done and decided by the units themselves. (don't know the formula used in game :bonk
I think only some scenarios have that rule activated because of what happened historically.
I bet the Russian ans the spanish campaigns have it (lots or scorched earth on them
) but probably the more "civilized" central Europe campaigns don't use that rule. (You can still order the destruction of depots with the button, of course).
Regarding supply: each unit or force needs a certain amount of supply. A big army will not have enough with the one produced on small cities, or even on a depot if there are to many troops.
To see the supply needs and production check the tooltips.
For the force needs, look for a supply icon on the top right of the units panel and pass the mouse over it to see the supply tooltip.
For the region production, it should be said on the region tooltip. But that is not all, additional supply can be sent form sorrounding regiosn or depots, depending of the distance and road network.
But in any case, if you force is lossing supply it is a sign that you are on a place where the supply network can't provide you with all the food your men neads. To fix this you can:
- Improve the network (creating a new depot o capturing a nearby city)
- Reduce the army size to a level you can feed there
- Move the army to a better place supply wise
- Send supply wagons back and forth from supply sources to the army (emergency measure)
