Thus the regulations of the feudal period encouraged the military disposition of the prelates, who, when the invaders burst in, readily raised the cry to arms. It will be remembered that when Hotspur and Douglas carried on their great trial at arms on Otterburne field, by the cloud-drifted light of the moon, the Bishop of Durham was marching with 10,000 men to ensure the defeat of the invaders. However, he arrived too late; the battle was over, Douglas slain, and the two Percies prisoners, and the Scots strongly posted to resist attack. A second battle must have been sanguinary, and the result doubtful, therefore the bishop decided not to take upon himself the responsibility of fighting, but withdrew his warriors, leaving the Scots to return unmolested to their own country. Chief among the amateur soldiers of the church in King Edward the First's days, was the proud and magnificent Bishop of Durham, Anthony de Beck, Patriarch of Jerusalem, and Lord of the Isle of Man. At Falkirk he drew an unrighteous sword against Wallace and the Scottish patriots. Previous to the battle he celebrated a soldier's mass on the field, clothed in knightly mail as he was, the long kite-shaped shield slung over his shoulder, the sword girt at his thigh. The ceremony over, he was ready to charge Wallace's schiltrons and archers, but the first column preceded him, led by the Earl Marshal, and Lincoln, and Hereford. He saw man and horse impaled on the huge Scottish spears, and the charging files rolled back in blood, while the Scottish arrows drifted into their ranks. He appreciated the valour of the enemy, and proposed to await the arrival of the numerous archers, who would speedily, and with little loss to themselves, shoot down the Scottish schiltrons. The men-at-arms were, however, eager to close, and Rudulf Basset scornfully advised the Lord Bishop to stick to his mass, while he led the charge. Thus rebuked, the bishop gave the word, leading, sword-in-hand, and furiously assailed the Scottish left, to be hurled back, again and again. The treacherous retreat of the Scottish cavalry left the schiltrons exposed to certain destruction, and the English archers shot them down without mercy. When Edward III. lay before Calais, he paid Thomas Hatfield, Bishop of Durham, 6s. 8d. per day, and his following in proportion, viz.:--three bannerets at 4s., 48 knights at 2s., 164 esquires at 12d., 81 archers on horseback at 6d. each per day.
