The Battle of Pinkie, also known as the Battle of Pinkie Cleugh, took place on 10 September 1547 on the banks of the River Esk near Musselburgh, Scotland. The last pitched battle between Scotland and England before the Union of the Crowns, it was part of the conflict known as the Rough Wooing and is considered to have been the first modern battle in the British Isles. It was a catastrophic defeat for Scotland, where it became known as "Black Saturday". A highly detailed and illustrated English account of the battle and campaign authored by an eyewitness William Patten was published in London as propaganda four months after the battle.
