Morphology
The verb 'fort' (to protect/fortify) combined with the particle 'up' yields a directly compositional meaning — to fortify oneself or take shelter — following common English verb+up patterns (e.g., 'hole up', 'lock up'). A B1 learner who knows the constituent meanings can reasonably infer 'to gather together for protection or defense', so the expression is transparent.
Etymology
Fort up comes from the image of people moving up into a fort and closing the gates to stay safe. That's why it means 'to gather together for protection'.
