Great Frost of 1709

[2] William Derham recorded in Upminster, Great Britain, near London, a low of −12 °C (10 °F) on the night of 5 January 1709, the lowest he had ever measured since he started taking readings in 1697.

Because the Russian troops were more prepared for the harmful weather and cautiously stayed within their camps, their losses were substantially lower, contributing heavily to their eventual victory at Poltava the following summer.

[4] France was particularly hard hit by the winter, with the subsequent famine estimated to have caused 600,000 deaths by the end of 1710.

[5][6] Because the famine occurred during wartime, there were contemporary nationalist claims that there were no deaths from starvation in the kingdom of France in 1709.

Elizabeth Charlotte, Madame Palatine, the Duchess of Orléans, had written a letter to her great aunt in Germany describing how she was still shivering from cold and could barely hold her pen despite having a roaring fire next to her, the door shut, and her entire person wrapped in furs.
