In 1332 war broke out again between England and Scotland, with Edward III supporting the claim of Edward Balliol (d.1363) to the Scottish crown. Balliol defeated the Scots at the Battle of Dupplin Moor, and Crabbe, who was in command of a fleet of ten Flemish ships, was also decisively defeated by English vessels in the Firth of Tay. After the battle Crabbe escaped to Berwick, but shortly thereafter was captured in a skirmish by the English soldier Walter de Manny. At the petition of an English Parliament convened at York, Edward III allowed Manny the 4300 marks ransom to be paid by the Scots for Crabbe, and ordered that Crabbe, still a prisoner in Scotland, be kept in chains until he had made restitution for his earlier robbery of the "Bona Navis". According to Lucas, Crabbe was fearful of his English captors, and succeeded in getting John Randolph, 3rd Earl of Moray, to request a safe conduct for him to the English court until Michaelmas 1333. Once Crabbe had arrived in England, Edward III determined to keep him there, and paid Manny 1000 marks for Crabbe's ransom. The English once again besieged Berwick in the spring of 1333, and after the Scots were decisively defeated on 19 July 1333 at the Battle of Halidon Hill they refused to ransom Crabbe from the English because, according to the Lanercost Chronicle, Crabbe had assisted Edward III at the siege of Berwick. The Scots then killed Crabbe's son. Edward III later rewarded Crabbe for his 'good service in the siege of Berwick' by pardoning him of all his crimes on both land and sea, and making him Constable of Somerton Castle.
