Edward III, who soon after assumed full power, was destined to make good the remark prevalent at this time, that the kings of England were alternately able and imbecile. He was a warlike and sagacious monarch, and inspired by all his grandfather’s desire of conquest. In 1329, Robert Bruce died, and was succeeded by his infant son DAVID II, to whom a young sister of the English king was married, in terms of the late treaty. Notwithstanding this connection, Edward aided a son of John Baliol in an attempt to gain the Scottish crown. Edward Baliol overthrew the Regent of Scotland at Duplin, September 1332, and for two months reigned as King of Scots, while David and his wife took refuge in France. Though now expelled, Baliol afterwards returned to renew his claims, and for many years the country was harassed by unceasing wars, in which the English took a leading part. But for his attention being diverted to France, Edward III would have made a more formidable effort to subdue Scotland, and might have succeeded. He was led into a long course of warfare with France, in consequence of an absurd pretension which he had made to its crown. In the victories which he had gained at Cressy (August 26, 1346) and Poitiers (September 17, 1356), the national valor, his own, and that of his celebrated son, the Black Prince, were shown conspicuously; but this lavish expenditure of the resources of his kingdom, in which he was supported by his parliament, was of no permanent benefit, even to himself, for whom alone it was made. In those days, almost all men fought well, but very few had the art to improve their victories. John, king of France, who had been made captive at Poitiers, and David, king of Scotland, who had been taken in 1346, while conducting an invasion of England, were at one time prisoners in England; but no permanent advantage was ever gained over either of the states thus deprived of their sovereigns. In 1361, after about twenty years of active fighting, the English king left France with little more territory than he had previously enjoyed. Edward had invaded Scotland with a powerful army in 1356, but without making any impression. The Scots, under David’s nephew, Robert Stuart, effectually protected themselves, not only from his arms, but from a proposal which David himself basely undertook to make, that Lionel, the third son of the English king, should be acknowledged as his successor. Edward died in 1377, a year after the decease of his son the Black Prince; and notwithstanding all their brilliant exploits, the English territories in France were less than at the beginning of the reign.
