The Easter Monday storm

posted in: Michigan Weather Forecast, Slim | 9

On Easter Monday April 13, 1360 during what has be come known as the Hundred Years War there was a major battle. Now a little history leading up to this battle. England and France were involved in one conflict or another over many centuries. The Hundred Years War was fought in spurts from 1337 to 1453. The cause of the war had to do with the death of a French monarch Charles IV who died without a male heir. During that period of time, women were not allowed the throne. The wife of the deceased king, Isabella wanted her nephew, King Edward III of England to take the crown. This didn’t sit well with France so Phillip VI, who was part of the French royal family became king. So the Hundred Years War was a power struggle for the rule of France.
King Edward III of England was bound and determined to conquer France, which he deemed rightfully his. At the time, residents of England lived under a feudal system which separated them into classes from kings and lords down to peasants and serfs. In 1346, King Edward III commanded every man-at-arms to join the army or send a substitute. Feudal lords were commanded to send men-at-arms and archers proportionately to their income. Many of them came from the peasants or serfs. If you didn’t obey this command, you were sent to prison.
In October of 1359, Edward took a massive army of 10,000 men across the English Channel to Calais in France. The invading force consisted of 4,000 men-at-arms, 5,000 mounted archers, and over 700 mercenaries from the European Continent. On Easter Monday, April 13th, Edward’s army arrived at Chartres. The French refused battle and took shelters behind their fortifications. Without much of a force to fight, it appeared that the French would be overwhelmed by the English siege. So, the old strategy of (lay low and hope for a miracle) was implemented again. Nightfall, on what would be a fateful evening, was fast approaching so the English army began to settle down and camp just outside of Chartres. By many accounts, soon after, the skies became angry, the wind became vicious, the temperature dropped quickly, bolts of lightning became more frequent. A cold, and wind-driven rain was falling when all of a sudden large balls of ice began to fall from the sky and pelted the army and their horses. The French had received their “miracle”.
The storm lasted less than an hour. All told, estimated casualties from the storm were nearly 1,000 soldiers dead, along with 6,000 horses. Two of the soldiers died after being struck by lightning. Edward was convinced that the storm was a sign from God as punishment for the pillaging of the French countryside during Lent. He turned toward the church of Our Lady at Chartres and vowed to the Virgin Mary that he would accept terms of peace from the French.
After some back and forth communication, the French wasted no time coming up with peace initiatives. In fact on the very next day, the French sent representative Androuin de la Roche with a proposal for a treaty. The Treaty Of Bretigny ended what was called the first phase of the Hundred Years War. The peace lasted nearly a decade before hostilities resumed once again.
There are plenty of questions surrounding this weather event. How can a hailstorm kill 1,000 men and 6,000 horses? Several publications indicate that this is exactly what happened but some chronicles over the centuries indicate that some men could have died from exposure (hypothermia) to the severe elements. Others indicate that the storm itself spooked hundreds of horses leading to a deadly stampede.

Wow, great history here. I have been a history buff for many years and am especially interested in medieval history. The English were well know for their deadly archers who had a much longer range with their longbows than the French who used crossbows. The Kings archers were required to shoot 10 arrows in 60 seconds and to hit their targets from 100 yards. The English longbows at the time were said to be 120 up to 150 lb. draw and the best could hit targets 300 yards away. I have made several longbows over the years ranging from 50… Read more »
