The destruction on Pylos by fire around 1180 suggests a violent destruction to the city. There is some evidence of Pylos expecting a seaborne attack with tablets at Pylos discussing "Watchers guarding the coast". The tablets do not give any context as to what is being watched for and why. Regardless of what the threat from the sea was, it likely played a role in the decline. It would have hindered trade and perhaps vital food imports.
