=15. Relations with England.=--In 1400, soon after the end of the truce, _Henry the Fourth_, who by a revolution had been placed on his cousin Richard's throne, revived the old claim over Scotland in order to make himself popular with the English. He announced his intention of coming to _Edinburgh_ to receive the homage of the King and of the nobles, and to enforce his demand he marched as far as Leith at the head of an army. This was the most harmless invasion on record, for, as usual, the Scots had got out of the way, and the English had to retreat without finding an enemy to fight with. About this time _George of Dunbar, Earl of March_, shifted his allegiance to _Henry_. He was offended because _Rothesay_ married a daughter of his great rival _Douglas_, instead of his own daughter _Elizabeth_, to whom he was betrothed. In 1402 he joined Sir Henry Percy, surnamed Hotspur, and defeated an invading body of the Scots under Douglas at _Homildon_. This was much such an affair as _Otterburn_, only this time the English won and Douglas was taken prisoner. He afterwards joined the Percies in their rebellion against Henry and fought with them at _Shrewsbury_. Albany had an army on the Border ready to help the rebels, but their defeat and dispersion brought his plan to nothing. But Albany hit on another way of threatening Henry. He entertained at the Scottish court a person whom he received as the dethroned _Richard_, who had been discovered in disguise, so the story ran, a fugitive in the _Western Isles_. In 1405, however, chance threw into Henry's hands an important prize. This was _James, Earl of Carrick_, second son of the King, and heir to the throne. He was captured by the English, in time of truce, while on his way to France, whither he was sent, nominally to be educated, but really to be out of the reach of his dangerous uncle. Thus, as the head of each government had a hostage for the good behaviour of the other, there was no open war between the two nations. In 1406 Robert died. =16. Albany's Regency.=--The death of Robert made no change in the government, though the young King was acknowledged as _James the First_. There was nominal peace with England, but the work of winning back the Border strongholds still went on. Jedburgh was retaken and destroyed, as the best means of securing it against foreign occupation in future.
