In 1333, Edward dropped all pretence of neutrality, repudiated the Treaty of Northampton, and attacked Scottish Berwick-upon-Tweed, Douglas' kinsman Sir Archibald Douglas, now Guardian of Scotland, rushed to meet the English host and battle commenced at Halidon Hill, resulting in a crushing defeat for the Scots. Sir Archibald was killed, William, the young Lord of Douglas also. Hordes of valuable hostages were taken. Young King David II, Douglas' Godson William Douglas and his brother John Douglas escaped to France. However, Edward chose to restore Balliol to Scotland and retired south. The supporters of King David elected two new guardians of the realm, John Randolph, 3rd Earl of Moray, Bruce's great-nephew and Robert Stewart, High Steward of Scotland and Bruce's grandson. In 1335 Edward decide to take matters into his own hands again and entered Scotland with a force large enough to occupy the whole south of the country, taking Edinburgh castle and heavily rebuilding and refortifying it.
