Alright, here are the pics, text to follow:
The operational context: (wrong)Sargot is pretty much the Vlandian's forward base against my faction (Khuzaits), with high prosperity, plentiful grain and five-recruiting slots. Whenever their parties want to raid, they start with the villages closest to Sargot. Whenever they want to besiege something, the army forms near Sargot. Whenever said army runs low on food or manpower, it goes to Sargot to get more.
So Sargot has got to go.
First things first, I gathered a mean mother****er of an army, well over 300 horse archers and 400 imperial legionaries, with another 500-600 other troops (some called in later, when the Vlandian army returned) to pad out the numbers. After that I found and followed an major (900 man) army heading towards Sargot, and waitedd for them to do their grocery shopping and leave. Next, I dismissed a party from my army which predictably went to begin raiding Sargot's villages. At the same time, I hadn't actually invested the town, to avoid drawing in defending parties/armies too early, but I blockaded the entrance with my army. Finally, once the Vlandian army had shown it wasn't going to attck and one village was burned while the other burning, I went ahead and invested the settlement.
- WrongSargot (just a hair under 6000 prosperity) was invested on Summer 15 with 541 total defenders (91 garrison) and over 600 units of food stockpiled.
- By Summer 18, food was down to ~400 and somehow 30 militia had disappeared for no apparent reason (they were not starving (yet)).
- Food stocks finally run down by Summer 21, 441 defenders remaining and they are losing 31 men per day.
- On Autumn 1, 402 defenders, 30 total men lost per day.
- Finally, Autumn 2 rolls around, down to 363 defenders (59 garrison) and starving at a rate of 27 per day.
I had to cut it short and launch the assault then, because something like 3000 Vlandians had showed up and had started to approach my siege camp regarding a number of complaints that I was blocking traffic in and out of the city.
This was a best case scenario in most respects:
- High prosperity
- Two village town and both villages raided
- Army bought out food
- My own army was uniquely powerful -- no serious risk from Vlandian relief parties for eight days
The defenders were starving at a satisfactory pace and in the end, I did do serious damage to their numbers (down to 363 from 541) but take away almost any element and I couldn't pull off it off. And again, most towns in 1.5.1
never reach 6000 prosperity. While they are also guarded by more than ~90 garrison, that doesn't directly translate to increased starvation to match prosperity consumption.
tl;dr sieging out a settlement under
very favorable conditions is alright. But anything less than that and it won't work well, or even necessarily at all, in the case of low prosperity settlements with granaries or three or more vilages or a closer relief army.
