A portrait of Henry VIII, based on an original by Hans Holbein the Younger Public domain via Wikimedia CommonsIn 1534, Henry VIII broke away from the Catholic Church, declaring himself supreme head of the Church of England. He expected his nephew, James V of Scotland, to follow suit, but James did not. When Henry scheduled a meeting with James in northern England in 1542, James blew it off.This breakdown in relations between the kingdoms set the stage for what historian Gervase Phillips has called one of the most extraordinary battles ever fought between English and Scot: the Battle of Solway Moss, which took place on November 24, 1542.Henry had broken with Rome in a bid to divorce his first wife, Catherine of Aragon, and become his kingdoms ultimate religious authority. In response to James disobedience, he first sent English troops up to Scotland to sack and burn a few towns and villages along the eastern marches, as the borderland was then known. James then sent his own troops to raid the western marches along the English side of the River Esk.A great army of Scotland, numbering 18,000, entered these marches, wrote William Musgrave, a sheriff who fought at Solway Moss, in a letter to an English courtier.

To enter into battle while knowing the slim odds would almost certainly be folly.But Wharton was a borderer, Phillips notes. He fought best on horseback with lance or sword and trusted his countrys defense more to walls of flesh and bone than stone.As the Scottish army crossed the River Esk at dawn, Wharton sent out light cavalry troops to penetrate the advancing line. The Battle of Solway Moss was underway.The English army moved quickly on the offensive, darting back and forth, advancing, retreating, attacking, and escaping in rapid, frustrating succession. They forced the Scots into an awkward position between the Esk and Solway Moss, a boggy, treacherous mire that hindered the movement of Scotlands cannons and heavy troops, now rendered useless in the face of the nippy English horsemen.

The man technically in charge, Robert Maxwell, Fifth Lord Maxwell, was locked in a power struggle with the Scottish kings favorite courtier, Oliver Sinclair.In the confusion, the Scots withdrew softly, Musgrave recalled. The English troops set on them and struck down many, and the rest fled over Esk.Whartons men pursued the Scots deep into their own territory, taking 1,200 prisoners and lots of Scottish artillery. When the battle was over, approximately 7 Englishmen and 20 Scots were dead. But the humiliation was too great for the young Scottish monarch. He died just three weeks after news of the defeat reached him.Though James had been ill for some time, Phillips writes, his cause of death remains unknown. Few doubt, though, that news of the debacle on the Esk was the final blow to the weary and already ailing king.Upon James untimely death, his only legitimate child, a 6-day-old daughter named Mary, ascended to the throne, reigning as queen of Scots for the next 25 years. The consequences of her reignand the aftershocks of the battle of Solway Mosswould reverberate for centuries.Get the latest stories in your inbox every weekday.Filed Under: British History, England, European History, Henry VIII, Mary, Queen of Scots, Medieval Ages, On This Day in History, Scotland, Tudors, Warfare
