It is said to have been chiefly through Mortimer's influence that, on April 24, 1328, a peace was concluded between England and Scotland, the chief provisions of which were that the Scots agreed to pay the sum of L20,000, and that Edward agreed to recognize the independence of the Scotch crown. The treaty was very unpopular in England, and it is not surprising, therefore, that, when Edward Baliol in 1332 made his attempt to mount the Scotch throne, Edward III. gave him indirect assistance, and that after Baliol's dethronement in 1333 an invasion of Scotland was resolved on. On July 19 Edward defeated the Scots at the battle of Halidon Hill. His army was in great danger, and was hemmed in by the sea, the Tweed, the garrison of Berwick, and the Scottish host, which far outnumbered the English. On the 20th he drew up his men in four battles, placing his archers on the wings of each; all fought on foot, and he himself in the van. The English archers began the fight; the Scots fell in great numbers, and others fled, the rest charged up the hill and engaged the enemy hand to hand. They were defeated with tremendous loss; many nobles were slain, and it was commonly said in England that the war was over, for that there was not a Scot left to raise a force or lead it to battle. Edward ordered a general thanksgiving for this victory. Receiving as the result of his victory the submission of the principal Scotch nobles, he annexed the whole of Scotland south of the Forth to his own crown, and allowed Baliol to reign over the remainder as titular king. Soon after, Baliol was again a fugitive, but was again aided by Edward to mount a nominal throne.
