Emboldened by success, he extended his ravages, till his deeds could no longer be ignored.[662] Stephen, at length fairly roused, marched in strength against him, determined to suppress the revolt. But the earl, skilfully avoiding an encounter in the open field, took refuge in the depths of the fenland and baffled the efforts of the king. Finding it useless to prolong the chase, Stephen fell back on his usual policy of establishing fortified posts to hem the rebels in. In these he placed garrisons, and so departed.[663] Geoffrey was now at his worst. Checked in extending his sphere of plunder, he ravaged, with redoubled energy, the isle itself. His tools, disguised as beggars, wandered from door to door, to discover those who were still able to relieve them from their scanty stores. The hapless victims of this stratagem were seized at dead of night, dragged before the earl as a great prize, and exposed in turn to every torture that a devilish ingenuity could devise till the ransom demanded by their captors had been extorted to the uttermost farthing.[664] I cannot but think that the terrible picture of the cruelties which have made this period memorable for ever in our history was painted by the Peterborough chronicler from life, and that these very doings in his own neighbourhood inspired his imperishable words. Nor was it only the earl that the brethren of Ely had to fear. Stephen, infuriated at the loss of the isle, laid the blame at their bishop's door, and seized all those of their possessions which were not within the earl's grasp. The monks, thus placed "between the devil and the deep sea," were indeed at their wits' end.[665] A very interesting reference to this condition of things is found in a communication from the pope to Archbishop Theobald, stating that Bishop Nigel of Ely has written to complain that he found on his return from Rome that Earl Geoffrey, in his absence, had seized and fortified the isle, and ravaged the possessions of his church within it, while Stephen had done the same for those which lay without it. As it would seem that this document has not been printed, I here append the passage:— "Venerabilis frater noster N. elyensis episcopus per literas suas nobis significavit quod dum apostolicorum limina et nostram presentiam visitasset, Gaufridus comes de mandeuilla elyensem insulam ubi sedes episcopalis est violenter occupavit et quasdam sibi munitiones in ea parauit. Occupatis autem ab ipso comite interioribus, Stephanus rex omnes ejusdem ecclesie possessiones exteriores occupavit et pro voluntate sua illicite distribuit."[666] This letter would seem to have been written subsequent to Nigel's return. The bishop, however, had heard while at Rome of these violent proceedings,[667] and had prevailed on Lucius to write to Theobald and his fellow-bishops, complaining—
