Got all 3 fights done on day 2 and all 3 again on day 3.
Yesterday I also made the 3 fights, for only one death (during the "average"). (I started the difficult fight after a retirement before having dead to improve my placement during the first round.)
So I had more than 1000 "spoils" for 200 deben.
Between 2 and 7 p.m., I removed all the goods buildings to build multi-story clay-houses and produce deben.
Since then I have 4 factories.
The difficulty is to manage the deben because it is impossible to predict the expenses, (according to the result of the fights the needs vary a lot). Knowing the composition of the defensive armies will allow a better estimate of this expenditure. So I started to note these compositions.
