While the siege of Calais had been in progress, the Scots had made a bold attempt to invade the north of England. The young king, David Bruce, grateful for the shelter which Philip VI. had given him in the days of his exile, had crossed the Tweed, in the hope of drawing Edward home, and so robbing him of the results of his campaign in France. But Queen Philippa summoned to her aid all the nobles who had not gone over-sea, and mustered them at Durham. David Bruce pushed forward to meet them, but at Neville's Cross he met with a crushing defeat. Once more it was found that the Scottish pikemen could not stand against the English archery. They were beaten with terrible loss, and the king himself and many of his nobles were taken prisoners and sent to London (October, 1346). [Sidenote: =The Black Death.=] Edward came back from Calais to England laden with glory and spoil, but all his plunder could not pay for the exhaustion which his heavy taxes and levies of men had brought upon his realm. The nation, however, was blinded to its loss by the glory of Crécy, and the war would probably have been continued with increased energy but for a fearful disaster which befell the land in the year after the fall of Calais. A great plague which men called "the Black Death" came sweeping over Europe from the East, and in the awful havoc which it caused wars were for a time forgotten. England did not suffer worse than France or Italy, yet it is calculated that a full half of her population was stricken down by this unexampled pestilence. Manor-rolls and bishops' registers bear out by their lists in detail the statements which the contemporary chroniclers make at large. We note that in this unhappy year, 1348-9, many parishes had three, and some four successive vicars appointed to them in nine months. We see how, in small villages of 300 or 400 inhabitants, thirty or forty families, from their oldest to their youngest member, were swept away, so that their farms reverted to the lord of the land for want of heirs. We find monasteries in which every soul, from the prior to the youngest novice, died, so that the house was left entirely desolate. And thus we realize that the chroniclers are but telling us sober, unexaggerated facts, when they speak of this as a pestilence such as none had ever seen before, and none is ever like to see again. It seems to have been an eruptive form of that oriental plague which still lingers in Syria and the valley of the Euphrates. It began with great boils breaking out on the groin or under the armpits, culminated in sharp fever and violent retching, and generally carried off its victims within two days.
