after capture a city, what happen?

hi. i never got a city from other player. If i attack a branch and capture it, where is the troops going to stay after battle?
Some player make the city 0 crop, and you capture the city and your troops stay in new city, then the city gonna starve the troops?

Yeah they will be in this city.... But how make crop 0? They cant selll when ur attacking

the spaces between attacks no cranny

Yeah they will be in this city.... But how make crop 0? They cant selll when ur attacking

It is possible, They can sell all the crops before i start to attack. Even the city generate crop, there might be 100 crops remaining. At this moment, i start to attack and capture it and my troops reside there, is it mean my troops gonna starve and die?

Here's what i am thinking.
The guy who capture my city and sell them right away or transport them. Whatever reason the warehouse is under 500 or 200. Now i start to attack him and capture it. After capture the city, my troops are in new city and out of crops. that's bad. Imagine you have 20k cats and the crops drain very fast.

Thats why for the final attks usual people send 1 cav or a little more, sending 20k cats on the last hit isnt smart because of that option stated above
