Any way to do the first expedition?

Hi guys,

I have a issue in game here. I got the mission to do my first expedition, but, the game don't explained how every unity worked clearly. I lost nearly all my troops and had no sufficient resources to replace them fast enough. The expedition expired and now I have a stuck quest in my quest book.

There's any way to get the map for this first expedition again?

you can buy the map from the merchant in the expedition tab, for 10 fish. before you start it again, try reading a guide to it, like this one:
settlersonlinewiki.eu/expeditions/training-expedition/
that site also has other useful information about expeditions

Thank you for the information. =)
