Quartermaster achievement

Complete the game without letting anyone in your caravan die to hunger.

How to get it
You must never have your days-of-supplies counter reach zero; when that happens, your population will start starving and die. So, you will have to purchase supplies in almost every market you come upon and limit your rest time as much as possible. Consequently, unless you play on the 'Easy' difficulty, you will probably suffer from one (or both) of the following problems, while trying to get the Quartermaster achievement: Both of these problems will make your battles harder to win.
 * Low Morale — Because you will not have supplies to 'spare' on resting to recover it.
 * Low Ranks for your heroes — Because you will spend most of your Renown for supplies.
