Shameful as the state of the realm had been under the rule of Edward of Carnarvon and his favourites, a yet more disgraceful depth was reached in the years of minority of his son. The young king was only fourteen, and the government fell into the hands of those who had set him on the throne, his mother and her paramour, Roger Mortimer. A council, headed by Henry Earl of Lancaster, was supposed to guide the king's steps, but as a matter of fact he was in Queen Isabella's power, while she was entirely ruled by Mortimer. They were surrounded by a guard of 180 knights, and acted as they pleased in all things. It was only gradually that the nation realized the state of affairs, for the murder of Edward II. was long kept concealed, and the relations of the queen and Mortimer were not at first generally known. [Sidenote: =Second Scottish invasion.--"The Shameful Peace."=] The first blow to the new government was the renewal of the Scottish war. In 1328, Robert Bruce broke the truce that he had made six years before. He was now growing advanced in age, and was stricken by leprosy, but he sent out, under James "the Black Douglas," a great host, 4000 knights and squires, and 20,000 moss-troopers, all horsed on shaggy Galloway ponies. They harried England as far as the Tees, and successfully eluded Mortimer, who went out against them, taking the young king with him. Outmarching the English day by day, Douglas retired before them across the Northumbrian fells, occasionally harassing his pursuers by night-attacks; he returned home with much plunder, leaving not a cow unlifted nor a house unburnt in all Tynedale. The English host came back foiled and half starved, and Mortimer, not daring to face another campaign, advised the queen to make terms with the Scots. Accordingly "the Shameful Peace" was signed at Northampton, by which England resigned all claims of suzerainty over the Scotch realm, sent back the crown and royal jewels, which Edward I. had carried off to London, and gave the king's sister Joanna to be wed to Bruce's eldest son (1328). [Sidenote: =Risings against Mortimer.=] Mortimer's failure led to insurrections against him; but they were mere baronial risings, not efforts of the whole people. Henry of Lancaster, who headed the first, was put down and heavily fined for his pains. Edmund, Earl of Kent, then took up the same plan, announcing that he would free his half-brother Edward II., who, as he was persuaded, still survived. But he fell into Mortimer's hands, and was beheaded. [Sidenote: =The king asserts himself--Mortimer executed.=]
