The Great Storm of 1703 is arguably the most severe storm or natural disaster ever recorded in the southern part of Britain. It affected southern England and the English Channel. A 120-mph (193-km/h) perfect hurricane, it started on 24 November, and did not die down until 2 December 1703.
Observers at the time recorded barometric readings as low as 973 millibars (measured by William Derham in South Essex) but it has been suggested that the storm may have deepened to 950 millibars over the Midlands.
At sea, many ships (many returning from helping the King of Spain fight the French in the War of the Spanish Succession) were wrecked, including HMS Resolution at Pevensey and on the Goodwin Sands, HMS Stirling Castle, HMS Northumberland and HMS Restoration, with about 1,500 seamen killed particularly on the Goodwins. Between 8,000 – 15,000 lives were lost overall.
