You will also need oil, and spice (get it at Tulga; it's too expensive elsewhere), as well as at least 4 units each of wine and ale. Then get 2 units each of as many different types of food as you can find, including hard to find items like chicken, fresh beef, pork and butter. Don't forget that your army will start eating the food right away, so if you can find most of your food items close by where your wife stays, that will be better for you.
