Another letter from Henry Percy to the council, dated June 4, 1401, is very interesting in several points of view. It proves that the negociations "carried in and out," mentioned in a letter written by the chamberlain of Caernarvon to the King's council, had been successful, and that the Scots had sent aid to the Welsh chieftain: it proves also that Hotspur himself was at this time (though bitterly dissatisfied) carrying on the war for the King in the very heart of Wales, and amidst its mountain-recesses and strongholds; and that Owyn was at that time assailed on all sides by the English forces, a (p. 112) circumstance which might probably have led to his "good intention to return to his allegiance," at the close of the present year. Henry Percy declares to the council that he can support the expenses of the campaign no longer. He informs them of an engagement in which, assisted by Sir Hugh Browe and the Earl of Arundel, the only Lords Marchers who had joined him in the expedition, he had a few days before routed the Welsh at Cader Idris. News, he adds, had just reached him of a victory gained by Lord Powis[114] over Owyn; also that an English vessel had been retaken from the Scots, and a Scotch vessel of war had been captured at Milford. Another letter, dated 3rd July, (probably the same year, 1401,) reiterates his complaints of non-payment of his forces, and of the government having underrated his services; it expresses his hope also that, since he had written to the King himself with a statement of his destitute condition, should any evil happen to castle, town, or march, the blame would not be cast on him, whose means were so utterly crippled, but would fall on the heads of those who refused the supplies. Henry IV. had certainly not neglected this rebellion in Wales, though evidently the measures adopted against the insurgents were not so vigorous at the commencement as the (p. 113) urgency of the case required. His exchequer was exhausted, and he had other business in hand to drain off the supplies as fast as they could possibly be collected. He was, therefore, contented for the present to keep the rebels in check, without attempting to crush them by pouring in an overwhelming force from different points at once. [Footnote 114: This nobleman, John Charlton, Lord Powis, died on the 19th of October following, and was succeeded by his son Edward, who, on the 5th of August, (probably in 1402 or 1403,) applied to the council for a reinforcement.--Min. of Coun.]
