Bait Taken (Ambition campaign) turn limit

[Endru1241]

Is it possible to do in 25 turns?
I tend to march all units given to north, west and east (up to a river) to destroy factories in as few turns as possible and focus on building port and workers.
Tried already switching from workers to ornithopters at 2,3 and 4 workers, but they are only good at destroying factories and ships - fortress shoots one time and they are gone after a turn.
I've tried different combinations what to do at the sea (mostly different number of triremes, catapult ships), but it's just too far to reach in time (weird few soldiers at far east) or insufficient force to kill fortresses.
