Edward Bruce agrees to what Scottish historian Patrick Fraser Tytler will describe five centuries later as "a truce involving conditions which ought on no account to have been accepted." As Tytler notes, the effect "was to check the ardour of the Scots in that career of success, which was now rapidly leading to the complete deliverance of their country; it gave the King of England a whole year to assemble the strength of his dominions... We need not wonder, then, that Bruce was highly incensed, on hearing that, without consulting him, his brother had agreed to Mowbray's proposals."
