But, this win did earn him an automatic leap from skilled defender to Field Defense Expert and he got the super cool and rare Skilled Poor Odds Defender virtue as well. Besides, I've grown attatched to him and he's done a fantastic job with the few resources available to him so I fell I owe him.
Keep this man, he's worth his weight in gold!!!

Interesting but unrelated point: If I have a unit with heaps of armour or weapon upgrades thats taken losses, and I retrain it in a province with no armourer, the new unit coems out with all the armour of the original unit! However, If I build another vanilla version of the unit in the same province, I cant merge them because they have incompatible upgrades. So, in low tech provinces it pays to retrain units rather than build and merge - it's like having the armourer buildings without having to build them.
I don't understand, I alway train troops with no armour upgrades to top off my armoured units. I train my battle troops in Sweden (with the arms & armour upgrades) and replace losses with locally trained troops...
