Questions on game play

[Gilgamesh]

First off, I'm pleased with the game. It's beautifully rendered, which was the first reason I bought it, but I also like how it's different enough from my other strategy games. I also appreciate something other than the standard western European historical models used in the other games I have.

My question has to do with what happens to troops after I take over a new town. It seems like they disappear. My king attacked a town, for example, and entered it, but the troops did not enter with him. Then I marched the troops back to my kingdom's original town. Later when I checked, the troops were not there. Am I missing something? Are the troops sent back to the fields as laborers?
