The Battle of Pinkie, fought on the banks of the River Esk on 10 September 1547, was another catastrophic waste of life encouraged by lack of discipline and weak command. The Duke of Somerset brought his troops, cavalry, and guns to the area, with naval support for his sixteen thousand men having to make their way along the beach. The Scots meanwhile, numbering around thirty-six thousand, held the best position behind the river, but lacked experience and an effective cavalry.
They were led by James Hamilton, 2nd Earl of Arran, whose lack of military ability caused him to misinterpret an English maneuver as their preparing to retreat. He brought his men across the river in an all-out attack, losing his advantage, and Somerset’s artillery laid in. When Huntly regrouped his men in the chaos, Arran thought they were deserting. Meanwhile, instead of attacking more of the enemy, many of the Highlanders were spending the crucial time robbing the bodies of the dead. The efficient army of Somerset slew fifteen thousand Scots and captured fifteen hundred while losing only five hundred of their own. ‘Black Saturday’ was a disaster for Scotland with so many lives lost, but it was also non-productive for victorious England since it forced Queen Mary further away from Prince Edward to the Dauphin.
