Expansion: Expand quickly along the coast, build a port and start constructing ships and small boats there, use the boats for fishing, use the ships to look for islands to settle on in the future, set up stations to pump water from the ocean and filter it so that it can be drank by the population, look for ores that may be exposed by the ocean near the shore.
Research: Try inventing explosives (if i haven't already) try making some form of simple hydraulics, keep devoliping mechanical technology like gears too.
I make signs to advertise to join the military, so people join the military. When I get at least 500 men, I will colonize northward and build lots of farms. I will make taxes and if I have tax I will increase it by 3%.
Animals:continue trying to tame the horse animal if we havent already and after that begin training (and maybe breeding if we have enough time) them to be able to carry heavy loads for my migration plans into the north
Buildings/Deconstruction: Begin destroying vacant houses that were occupied by now deceased villagers so we can make more field hospitals and speed up reconstruction of other buildings (ie actual hospitals and barracks)
research: far deadlier weapon types, like ceramic tipped arrows or something like that to cause as much damage as possible to the target. Work on stronger metals using the newfound iron. Unless we can't find any stronger alloys, hold off on making anything with the iron. this includes the catchbows in my previous order. Only use the alloy (or just iron if no stronger alloys are found) with the sharpshooting catchbows for now.
Infrastructure: federal mailing and postal services will be opened, with government hired deliverymen.
Also, maybe make a microscope, in the same way as the telescope.
General: Build waterwheels along any rivers or streams, especially if they are near farmland. Use them to grind wheat for flour. Make a massive telescope for seeing into space for studies on the sky, for better navigation and finding when the best times to plant are, based on the time which stars show up and when.
Military: Make catchbows with the steel/iron arms (sorry for copying you loiosh i am losing my creativity) to allow for the arms to be pulled further back, making them far more powerful. Pure alchohol based explosives for traps, at least for now. Train sharpshooters with the scoped catchbows
