 Once ashore, one of the first tasks undertaken by the sailors was to set up a pair of cannons on the promontory in the harbour to provide some defence.This battery became known as Fort Cockburn (renamed in the middle of the century Fort Thornton).A second fort was established on a site called Goat Hill further to the west in around 1860 (Fort Hayes) and a third, Fort Bedford, on the hill overlooking the town called Cross Hill.
