This was the first time that a prelate had suffered capital punishment in England. Prelates had been imprisoned and punished by forfeiture and banishment, but no king had yet dared to put to death a bishop; and the circumstance did not pass without the Pope launching the thunders of excommunication against all persons concerned in this ominous innovation, though without specially naming the king. The archbishop, on hearing his sentence, protested that he never intended any evil to the person of Henry, and merely sought redress of grievances; but after having twice incited the insurgents to arms, and being believed to have written the last proclamation, if not that also at Shrewsbury, he was not likely to obtain credence. When afterwards the king called upon the House of Lords to record a judgment of high treason against the archbishop and the Earl Marshal, they demurred, and required the question to lie over till the next Parliament—a significant hint of their disapproval, which Henry was wise enough to take. The matter was never mentioned again.
Henry punished the city of York for its disposition to support the views of the archbishop, by depriving it of its franchises, and then, at the head of 37,000 men, marched in pursuit of the Earl of Northumberland and Bardolf. Northumberland had delayed his demonstration this time to secure the assistance of Albany, the regent of Scotland, and aid from France. He had readily formed an alliance with Albany, but failed in procuring any support from the French court. As Henry advanced north, Northumberland retired. Henry took successive possession of the duke's castles of Prudhoe, Warkworth, and Alnwick; and as he drew near Berwick, Northumberland, who never showed much courage, surrendered it into the hands of the Scots, and fell back still farther on his Scottish allies. The Scots themselves, not thinking the town tenable against Henry's forces, set it on fire and deserted it. The castle alone appeared disposed to make resistance; but the shot of an enormous cannon having shattered one of the towers, it opened its gates, and the son of the Baron of Graystock, with the six principal officers, was immediately executed. Henry turned southward victorious, and at Pontefract—which no thoughts of the murder he was charged with committing prevented him from visiting—he conferred upon his queen the several great estates of the Earl of Northumberland and Bardolf.
Henry now marched to Wales, whither he had sent his son, Prince Henry, in the spring. This gallant young prince, who had acquired such renown on the field of Shrewsbury, had pursued Glendower into his fortresses, with all the ardour and impetuosity of youth. For some time that artful general eluded his attacks, and set him at defiance by a variety of stratagems, but in the month of March he had obtained a signal victory over the Welsh at Grosmont, in Monmouthshire, and taken Griffith, the son of Glendower, who commanded, prisoner. He next laid siege to Lampeter Castle, in Cardiganshire, and after a long siege reduced it. But now the French appeared upon the scene with a force of 12,000 men, if we are to credit Otterburne.
Glendower, finding his power gradually undermined by the efforts of Henry and his valiant son, had applied to the French, or, as some writers assert, had gone in person to solicit the aid of France. That country at the time was in a deplorable state of misgovernment. The malady of Charles VI. had reduced him to a condition of absolute imbecility. The powerful Duke of Burgundy was dead, and the dissolute Orleans, living in open adultery with the queen, had usurped the whole powers of the state. As Albany was in Scotland, so was Orleans in France. Hating Henry with an inveterate hatred, he readily promised Glendower his assistance. A fleet was fitted out and entrusted to the Count of La Marche, a gay young prince of the royal family, but engrossed in pleasures and gaieties. It was so late in the year when this courtly admiral reached his fleet at Brest, that his most sensible followers refused to venture to sea; and with a fragment of his force La Marche made an abortive descent on the English coast at Falmouth.
In the spring of 1405, however, a fresh fleet, assembled by the resolute Orleans, reached Wales, and debarked at Milford Haven. The fleet consisted of 120 ships, and had taken on board a great number of cavalry horses, which, however, had nearly all perished during the stormy passage; and no sooner was the fleet moored than the squadron of the Cinque Ports sailed in after it, and burnt fifteen ships. It, moreover, cut off all supplies by sea, and soon after succeeded in capturing a portion of the French transports bringing ammunition and provisions.
The French army was commanded by the Count Montmorency, Marshal de Rieux, and the Sire de Hugueville, grand master of the arbalisters (or crossbowmen). They marched to Haverfordwest, and burnt the town, but suffered great loss in attempting to take the castle, and were repulsed. They next advanced to Carmarthen, laying the country waste as they went; they took Carmarthen, and there were joined by Owen Glendower with a force of 10,000 men. This united force took its way towards England, and Prince Henry, being in possession of an inferior force, was compelled to avoid an engagement.
It was this which had made Henry hasten his march from the north. Before setting out, he granted the Isle of Man, forfeited by the Earl of Northumberland, to Sir John Stanley, in whose family it continued till the reign of Elizabeth. On reaching Hereford the king was compelled to issue a proclamation representing that the kingdom was in great danger from the junction of the French and the Welsh; that his finances were totally exhausted; and that the tenths and fifteenths granted by Parliament could not be levied till Martinmas. He, therefore, commanded the sheriffs of all the neighbouring counties to summon before them the richest men of their several shires, and prevail upon them to advance money on the credit of the taxes already voted.
To such extremity was Henry IV. reduced, in one of the most critical epochs of his troubled reign; and this total want of means for paying and feeding his army delayed him so long, that it was not till late in the year that he came face to face with the invaders. They had now reached the very gates of Worcester, and menaced that town. Henry having united his forces with those of his son, now advanced upon the enemy, who were posted on a considerable hill, and took up his position on an opposite height. For eight days the two armies lay with a deep valley between them, neither of them willing to risk the loss of its vantage ground, and give battle under the unequal circumstances. There were occasional skirmishes, and three of the French lords were slain, including the brother of the marshal.
At length the Welsh and French beat a retreat into Wales, and Henry pursued them; but having reached their marshes and mountains, they turned upon the king's forces when they had, in their ardour, advanced incautiously amongst them, and inflicted great loss upon them, taking or destroying fifty of his wagons, containing the most valuable portion of his baggage. It was now the middle of October; the season was such as all the world then believed to be at the command of Glendower—tempestuous and incessantly raining. The roads became impassable, provisions were unattainable, and the king was heartily glad to draw off his army. Nor were the French less delighted to quit the country of the great necromancer, where they reaped more labours than laurels; and soon after they embarked and sailed back to France.
Northumberland and Bardolf were soon compelled by the manœuvres of Henry to escape from Scotland. The Scottish noblemen who had been kept prisoners in England ever since the battles of Homildon Hill and Shrewsbury, were offered by Henry their liberty if they would persuade their friends in Scotland to seize and deliver up these noblemen. This disgraceful scheme was readily adopted by the Scottish prisoners and their friends, and would have been carried speedily into execution; but the news of it reached the ears of the brave Sir David Fleming, a staunch friend of the Percies. It must be remembered that not only was the Earl of Douglas, but Murdoch, the son of the regent Albany, still amongst the prisoners of war in England; and, therefore, both Albany and the friends of Douglas, combining the most powerful party in Scotland, were engaged in this most dishonourable conspiracy for the betrayal of Northumberland, his young grandson, Henry Lord Percy, and Lord Bardolf. Sir David Fleming, disdaining to connive at so base a treason against the honour and hospitality of Scotland, gave the English noblemen timely warning. They escaped; but Sir David, as we have related, returning from conducting Prince James to North Berwick on his way to France, was set upon by the son of Douglas and the connections of the other prisoners in England, and lost his life for his noble conduct. Northumberland and Bardolf made their escape to Glendower in Wales.
