When John learned what steps had been taken in contravention to his authority, his rage knew no bounds; and, in his excitement, he bethought him of punishing the monks for their servility to the Pope. Accordingly he sent two knights to seize the convent and drive the monks out of their cloisters; and the unfortunate men were expelled at the point of the sword. But the king soon discovered that this had been rashly done. Indeed, the Pope no sooner became aware of his wishes being treated with such disrespect than he sent three bishops to threaten John and his kingdom with an interdict if he did not yield; and all the other bishops coming to the king, implored him on their bended knees to save himself from the evil that was threatened by accepting Stephen Langton as primate, and allowing their monks to return to their convent and take possession of their property. John stood upon his dignity, and refused to bend an inch. In vain Innocent demanded redress, and indulged in threats of bringing spiritual artillery into play. The king, who believed he had justice and law on his side, and who believed also that, if supported by his subjects, he had little to fear in a contest with the court of Rome, boldly answered with defiance; and at length, in 1208, Innocent laid the kingdom under interdict, preparatory to excommunicating the king, in the event of his continuing refractory. The papal interdict plunged England in gloom, and caused the utmost consternation. The churches were closed; no bell was tolled in their steeples; no services were performed within their walls; and the sacraments were administered to none but infants and the dying. Marriages and churchings took place in the porches of churches; sermons were preached on Sundays in the churchyards; and the bodies of the dead were interred silently and in unconsecrated ground. No bells summoned the living to their religious devotions, and no mass or prayer was offered for the souls of the departed. After this had continued for some time, Innocent finding that John gave no indications of a desire to yield, formally excommunicated the king, absolved his subjects from their allegiance, and exhorted all Christian princes to aid in dethroning him. Philip Augustus did not require much prompting. Willingly and readily he assembled a fleet at the mouth of the Seine, and mustered an army to invade England. John was exceedingly nervous about the future. Indeed, it is said that, in his alarm, he sent ambassadors to ask the aid of the Moorish King of Granada. If so, the mission came to nought. However, an English fleet crossed the Channel, and, after destroying the French squadrons in the Seine, burned the town of Dieppe, and swept the coast of Normandy. Even at that early period of our history, the naval power of England was not to be resisted.
