On the first mission, you have a mass number of troops waiting for your command. Your mission is to gather at least 50 to 51 slaves. Just in case if you have 51, as long as you have reserves and around 10,000 gold, you can get gold through the villages and temples on your way to the are. On the northern part, you will encounter some natives, kill them and capture their dwelling and you can get gold and food (be careful, the food supply is limited so you better hurry.) Don't go directly to the other side of the river because that place is filled with natives that might get you killed, so split up your troops, use the pike men first because they are more resistant to arrows and any kind of weapon the natives use. At least do a charge, use the musketeers if necessary, you better not use your musketeers at that point because the native American archers can actually kill all your musketeers. Go and explore the eastern part and you will see a village, they will negotiate with you. On the western part of the island you are on, explore the area and you will see a house, having 4 to 5 peasants and on the west you will see a house with peasants, they will talk to you and you must negotiate with them. So in order for you to gather the exact amount of gold, go north and you will find 4 buildings, get inside for defense because there are natives that surround it after that you will gain gold and food, that's about it.
I will continue with this later.
