Bishops' Wars: Scottish Covenanter forces led by Alexander Leslie defeated the English army near Newburn, England.

The Bishops' Wars were two separate conflicts fought in 1639 and 1640 between Scotland and England, with Scottish Royalists allied to England. They were the first of the Wars of the Three Kingdoms, which also include the First and Second English Civil Wars, the Irish Confederate Wars, and the 1650 to 1652 Anglo-Scottish War.

Covenanters were members of a 17th-century Scottish religious and political movement, who supported a Presbyterian Church of Scotland and the primacy of its leaders in religious affairs. It originated in disputes with James VI and his son Charles I over church organisation and doctrine, but expanded into political conflict over the limits of royal authority.

Alexander Leslie, 1st Earl of Leven was a Scottish army officer. Born illegitimate and raised as a foster child, he subsequently advanced to the rank of field marshal in Swedish Army, and in Scotland became Lord General in command of the Army of the Covenanters, a privy councillor, captain of Edinburgh Castle, Lord Balgonie and Earl of Leven. In England he commanded the Army of the Solemn League and Covenant and was senior commander of the Army of Both Kingdoms (1642–1647). Leslie served in the Thirty Years' War, the Bishops' Wars, and most of the English Civil War, fighting primarily in the First English Civil War. Leslie would live a long life, dying roughly at the age of 80 or 81.

The Battle of Newburn, also known as the Battle of Newburn Ford, took place on 28 August 1640, during the Second Bishops' War. It was fought at Newburn, just outside Newcastle, where a ford crossed the River Tyne. A Scottish Covenanter army of 20,000 under Alexander Leslie defeated an English force of 5,000, led by Lord Conway.
