On 11th of August 1332 the Battle of Dupplin Moor was fought between supporters of  David II King of Scots, the son of Robert Bruce, and English-backed invaders supporting Edward Balliol, son of John I Balliol King of Scots.

It took place a little to the south-west of Perth, Scotland, when a Scottish force commanded by Donald, Earl of Mar, estimated to have been stronger than 15,000 and possibly as many as 40,000 men, attacked a largely English force of 1,500 commanded by Balliol and Henry Beaumont, Earl of Buchan. This was the first major battle of the Second War of Scottish Independence.

It was a disastrous defeat for the Scots, many of whom were trampled, trapped with no room to manoeuvre as their own forces arrived into the valley.

The immediate political outcome was dramatic but in the medium term effects were limited. Dupplin Moor enabled Edward Balliol to depose Bruce, being crowned king of Scotland on 24th September 1332. However he was soon forced to flee to England, on the 17th December, by the forces under the Earl of Moray. Edward III then gave support to Balliol, raising forces to besiege Berwick, then in Scottish hands, leading directly to the battle of Halidon Hill. Dupplin Moor
