Port Egmont (Spanish: Puerto de la Cruzada; French: Poil de la Croisade) was the first British settlement in the Falkland Islands, on Saunders Island off West Falkland, and is named after John Perceval, 2nd Earl of Egmont, who was First Lord of the Admiralty at the time of its founding.
This was to secure possession, and McBride ordered one of the ships to stay at Port Egmont, and develop the settlement, resulting in several permanent buildings and a garrison.
In January and February the thermometer at Port Egmont rose to 15 °C (59 °F), but no higher; in August, it once fell to −7 °C (20 °F), but was seldom lower than 0 °C (32 °F).
In early 1770 Spanish commander Don Juan Ignacio de Madariaga briefly visited Port Egmont.
He returned from Montevideo on 10 June with five armed ships and 1400 soldiers forcing the British to leave Port Egmont.
