On May 15, 1789 Martinez chose the location of his fortification at the entrance of Friendly Cove on Hog Island. Work progressed so that on May 26 they were able to place their artillery followed by the construction of barracks and a powder storeroom. On June 24, 1789 a salvo was fired from the new fort and the Spanish ships in what Martínez considered an official act of possession of Nootka Harbour. On July 4, the American vessels and their captains Gray and Kendrick (who had arrived in the harbour 7 months earlier than Martinez) fired salvos and fireworks in recognition of their recent independence from Britain accompanied by a further salvo from the Spanish fort.1:288
