HMS Discovery was a Royal Navy ship launched in 1789 and best known as the lead ship in George Vancouver's exploration of the west coast of North America in his famous 1791-1795 expedition. She was converted to a bomb vessel in 1798 and participated in the Battle of Copenhagen. Thereafter she served as a hospital ship and later as a prison hulk until 1831. She was broken up in 1834.

The Nootka Crisis, also known as the Spanish Armament, was an international incident and political dispute between the Nuu-chah-nulth Nation, Spain, the Kingdom of Great Britain, and the fledgling United States of America triggered by a series of events revolving around sovereignty claims and rights of navigation and trade. It took place during the summer of 1789 at the Spanish outpost Santa Cruz de Nuca, in Nootka Sound on Vancouver Island in present-day British Columbia, Canada. The commander of the outpost, Jose Esteban Martínez, seized some British commercial ships which had come for the maritime fur trade and to build a permanent post at Nootka Sound. Public outcry in Great Britain led to the mobilization of the Royal Navy, and the possibility of war. Both sides called upon allies, the Dutch joined the side of Great Britain; Spain mobilized her navy and her key ally France also mobilized theirs, but the latter soon announced they would not go to war. Without French help, Spain had little hope against the British and the Dutch, resulting in Spain seeking a diplomatic solution and making concessions.
