• 1318 – Berwick-upon-Tweed is captured by the Scottish from England.
• Between 1315 and 1318, Scottish armies, sometimes with the help of Flemish and German privateers, besieged and blockaded the town, finally invading and capturing it in April 1318. England retook Berwick some time shortly after the Battle of Halidon Hill in 1333. In October 1357, a treaty was signed at Berwick by which the Scottish estates undertook to pay 100,000 marks as a ransom for David II of Scotland, who had been taken prisoner at the Battle of Neville's Cross on 17 October 1346.
