Ever since Robert Bruce's victory at the Battle of Bannockburn in 1314, the Scots had taken the initiative in the wars with England, raiding deep into the north of the country repeatedly and with comparative ease to attempt to force the English to the peace-table.

In early 1322, the situation had become critical, with some senior English noblemen, headed by Thomas of Lancaster, preparing to enter into an alliance with the Scots.

It seems unlikely that Bruce had much confidence in Lancaster, who referred to himself as 'King Arthur' in his negotiations with the Scots, but he was quick to take advantage of the threat of civil war in England.

Scarcely had the truce of 1319 expired in January 1322 than Sir James Douglas, Thomas Randolph, 1st Earl of Moray and Walter Stewart came over the border on a large-scale attack on the north-east.

Edward ignored the Scots, instructing his lieutenant in the north, Sir Andrew Harclay, the governor of Carlisle, to concentrate his efforts against the rebel barons, whom he finally defeated at the Battle of Boroughbridge.

To dislodge him from his strong position on the high ground Bruce used the same tactics that brought victory at the earlier Battle of Pass of Brander.

Edward—"ever chicken-hearted and luckless in war"—was forced to make a rapid and undignified exit from Rievaulx, fleeing in such haste that his personal belongings were left behind.
