Berbera was a city in constant anarchy, it was the busiest port in the horn so the tribes inhabiting it (HA) would destroy the forts of one another often. Even in one of the sources you quoted, it mentions Sharmarke erected his forts on 3 different occasions because they kept getting destroyed (by locals)
It obviously was a well guarded and fortified port before that dispute over trade access from what you shared from that 1801 letter
They ended up resolving it by creating Bulxaar as a sister port.
