December 30, 1970 – Sonny Liston dies in suspicious circumstances

Sonny Liston was found dead by his wife on January 5, 1971, but the date that appeared on his death certificate is December 30, 1970. This date is based on a police estimate, but since the police also ruled that his death was due to a heroin overdose and Liston’s autopsy showed no evidence of such an event, the date may also be suspect.

In addition, several things one would expect to find at the site of a heroin injection, such a tourniquet or similar to tie off with and a spoon to cook in, were absent from the scene of Liston’s death. Nor did Liston have any history of heroin use – and it’s hard to believe that he could have kept such a thing a secret, given his well-known love of drinking and partying to excess.

It is widely believed that his death was a result of a criminal hit, ordered by unknown underworld figures, and that the police investigation and its findings were a coverup.

December 14, 1812 — French begin retreat from Moscow

It is possibly the most notorious defeat in military history, a textbook example of strategic and logistical errors: Napoleon’s retreat from Moscow, in the chilly Winter in 1812. This day, December 14, marks the date upon which the French were finally expelled from Russian territory.

A combination of factors – worsening weather, an over-extended supply chain, the scorched-earth policy of the Russian peasantry and the guerilla tactics of the Russian military being the most well-known – came together to make the French position in Moscow untenable. When Napoleon left the army to shore up his political position in France, the already poor morale of the French army sank lower still, and the remaining commanders ordered a retreat, most likely in order to prevent a mutiny.

Thus began one of the most infamous and fatal retreats the world has ever seen. In addition, the defeat was the beginning of the end for Napoleon, whose fortunes declined over the next few years, finally culminating in his defeat in the battle of Waterloo in 1815

July 1, 1798 – France invades Egypt

Napoleon had grand dreams of empire when he embarked for the Middle East in 1798. And at first, they seemed warranted. His forces took Malta in June 1798, and then eluded the British Navy for nearly two weeks as they crossed the Mediterranean to Egypt. On July 1, the fleet landed at Alexandria, although Napoleon himself was still at sea.

Perhaps this is why his orders were ignored, and his forces invaded the city during the night, taking it with little resistance. Napoleon’s Egyptian campaign was a mixed success: on land his forces triumphed over the Egyptians and ended the rule of the Mamelukes; at sea, they lost a disastrous engagement with the British. Undaunted, Napoleon continued with his plans to invade Syria, but a combination of harrying from the British at sea and the Ottomans on land, coupled with uprisings of the conquered (notably at Cairo in October 1798) eventually forced him to withdraw. The lasting results of his invasion were few: Egypt remained an Ottoman possession, although the decline of the Ottoman Empire was now undeniable; and the discovery of the Rosetta Stone led to great advances in archaeology, making it possible to translate hieroglyphics into modern languages.

November 15, 1793 — Mason and Dixon arrive in Philadelphia

Charles Mason and Jeremiah Dixon were a pair of English astronomers who were hired by Thomas Penn and Frederick Calvert, respectively the proprietors of Pennsylvania and Maryland, to resolve a boundary dispute between the two colonies in 1763. The two had worked together for two years before that, Dixon serving as Mason’s assistant.

The survey took three years to complete – and the pair remained in America for another two years after that, being admitted to the American Society for Promoting Useful Knowledge, in 1768, before they left American in the same way they had entered it: via Philadelphia.

October 18, 1767 — Mason and Dixon complete the surveying of the Line between Maryland and Pennsylvania

Charles Mason, a fellow of the Royal Society and noted astronomer, and his sometime assistant, land surveyor and amateur astronomer, Jeremiah Dixon, were hired by certain wealthy interests in what was then the British colony of America to conclude a number of difficult boundary disputes in the young colonies.

Landing in Philadelphia in 1763, Mason and Dixon spent the next four years painstakingly measuring and fixing the proper boundaries between the various colonies, ceasing their work on October 18, 1867. (A team of their subordinates completed the survey in 1787.)

The lines they laid down, although resurveyed since that time, formed the basic lines of the borders between the colonies (and later the states) of Delaware, Maryland, Pennsylvania and West Virginia. Later, as these states took different sides in the Civil War, the line came to symbolise the political and cultural border between the southern and northern states.
