By this point Grosmont's future relationship with the crown was "actively assured" comments Fowler. The early 1340s were a period of financial constraint for Grosmont due to his acting as a broker for a number of loans between the King and Flemish bankers. As well as undergoing a number of periods of imprisonment as a debtor, Grosmont was eventually to raise numerous large sums, including £969 to gain the release of the royal crown, which Edward had pawned, and £1,500 worth of jewels to free the King after he had offered himself as security for loans. Scotland In 1328 Edward III's regents had agreed to the Treaty of Northampton with Robert Bruce, King of Scotland (), but this was widely resented in England and commonly known as turpis pax, "the cowards' peace". Some Scots nobles refused to swear fealty to Bruce and were disinherited. They left Scotland to join forces with Edward Balliol, son of King John Balliol (), whom Edward I had deposed in 1296. One of these was Grosmont's father-in-law, Henry de Beaumont, Earl of Buchan and veteran campaigner of the First War of Scottish Independence. Robert Bruce died in 1329; his heir was 5-year-old David II ().

In 1331 the disinherited Scottish nobles gathered in Yorkshire, and led by Balliol and Beaumont plotted an invasion of Scotland. Edward III was aware of the scheme but turned a blind eye. Balliol's forces sailed for Scotland on 31 July 1332. Five days after landing in Fife, Balliol's force of some 2,000 men met the Scottish army of 12,000–15,000 men and crushed them at the Battle of Dupplin Moor. Balliol was crowned king of Scotland at Scone on 24 September 1332. Balliol's support within Scotland was limited and within six months it had collapsed. He was ambushed by supporters of David II at the Battle of Annan a few months after his coronation and fled to England half-dressed and riding bareback. He appealed to Edward III for assistance. On 10 March Balliol, the disinherited Scottish lords and some English magnates crossed the border and laid siege to the Scottish town of
