Great Hurricane of 1780 - Impact

Impact

The Great Hurricane first began affecting Barbados with rain late on 9 October. Northwesterly winds increased through the day on 10 October. The ships in the bay broke their moorings by 4 pm, and the "full impact" arrived by 6 pm. The wind gradually backed to westerly through the night and peaked at midnight. Wind speed returned to normal by 8 am on 11 October. These winds suggest that the eye of the storm passed north of Barbados. The hurricane produced violent winds "so deafening that people could not hear their own voices." The hurricane stripped the bark off trees and left none standing on the island. Even the strongest hurricanes do not strip the bark off trees, and Cuban meteorologist José Carlos Millás estimates that this phenomenon would require rain and winds over 200 miles per hour (320 km/h). The winds also destroyed every house on Barbados. The hurricane also destroyed all forts on the island. According to British admiral George Brydges Rodney, 1st Baron Rodney, the winds carried their heavy cannons aloft 100 feet (30 m). About 4,500 people died on Barbados.

In Saint Vincent, the hurricane destroyed 584 of the 600 houses in Kingstown. At Grenada, 19 Dutch ships were wrecked. On Saint Lucia, rough waves and a strong storm tide struck the fleet of British Admiral Rodney at Port Castries, with one ship destroying the city's hospital by being lifted on top of it. The hurricane destroyed all but two houses at Port Castries, and throughout the island about 6,000 perished. Among the ships lost from Rodney's fleet were the frigates HMS Phoenix wrecked on the Cuban coast, and HMS Blanche which disappeared without a trace, the sixth rate frigates HMS Andromeda and HMS Laurel which were wrecked on Martinique with heavy loss of life and five other smaller vessels either wrecked or foundered. By far the worst losses in the British fleet however were among the squadron of Rear-Admiral Joshua Rowley, which was caught at sea by the hurricane off the San Domingo coast. Ships of the line HMS Thunderer which foundered with all hands, and HMS Stirling Castle which was smashed on the coast with fewer than 50 survivors, were lost and the remaining six ships were all severely damaged.

A fleet of 40 French ships involved in the American Revolutionary War capsized as a result of the hurricane off Martinique; about 4,000 soldiers drowned. Among the French losses were the ships of the line Palmier, Intrépide and Magnifique and the frigate Junon. The hurricane produced a 25-foot (7.6 m) storm surge on Martinique, destroying all houses in Saint-Pierre; 9,000 died on the island. High winds, rains, and storm surge caused severe damage at Roseau, Dominica. A storm surge also struck the south coast of Guadeloupe and caused considerable damage. Strong winds affected Antigua and Saint Kitts, and in the latter island, many ships were washed ashore. A Dutch sea-officer whose ship was blown from St. Eustatius to Martinique by the hurricane reports on the damage in Saint-Pierre (Martinique), St. Vincent and St. Lucia. On his return to St. Eustatius he reports that here "too some houses are destroyed" and the sea water ruined the merchandise that was left on the beach. However, he says that the situation was not as bad as on the French and English islands and does not speak of any dramatic death toll (Jong, C. de. Reize naar de Caribische Eilanden, 1807. p. 140).

Heavy damage was reported in southern Puerto Rico, primarily in Cabo Rojo and Lajas. Severe damage also occurred in the eastern region of Santo Domingo. The hurricane later grounded 50 ships near Bermuda. Throughout its path, the hurricane killed over 20,000 people, possibly as high as 24,000, making it the deadliest hurricane in Atlantic hurricane history.
