After the Scottish defeat at Pinkie, no Anglo-Scottish battle had occurred until this. Sir John Carmichael assembled a small band of pikemen and gunmen in Liddesdale. He was preparing to meet Sir John Forster at Carter Bar for a truce. Sir John Forster also gathered an army. Forster was known for double-dealing, and Carmichael knew it could turn into a battle.
The Scots met with the English under Forster, and insults flew from both sides. The truce was not going well and in time it turned into a battle, starting with cannon and bow shots from the English. The English were getting the better of the infantry match. But the timely arrival of Scottish reinforcements from Jedburgh gave the Scots an advantage. They began to break the English lines and in time, the English were routed: the Scots proved victorious, and drove the English off. Forster was captured, and George Heron, along with his brother John Heron and many other notable English nobles were killed. English prisoners, however, were treated humanely and then released.
The story of the skirmish was turned into a Border ballad. As well, on the Cheviot Hills, near the place where the battle was fought a monument was built in commemoration of the battle. It read, "On this ridge, June 7th, 1575 was fought one of the last border raids, known as The Raid of the Redeswire". This is a misnomer, as it wasn't really a raid and did not take place in the Redeswire.
