Even he, however, strong though he was, could scarcely have attempted to stem the tide, while the flood of reaction was at its height. He watched, no doubt, for the first signs of an ebb in Stephen's triumph. It was not long before this ebb came in the form of that illness by which the king, as we saw, was struck down about the end of April, on his way south, at Northampton.[507] The dismissal of the host he had so eagerly collected was followed by a rumour of his death.[508] No one, it would seem, has ever noticed the strange parallel between this illness and that of 1136. In each case it was about the end of April that the king was thus seized, and in each case his seizure gave rise to a widespread rumour of his death.[509] On the previous occasion that rumour had been followed by an outburst of treason and revolt,[510] and it is surely, to say the least, not improbable that it now gave the sign for which Geoffrey was watching, and led to the extraordinary charter with which we have here to deal. The movements of the Empress have also to be considered in their bearing on the date of the charter. We learn from William of Malmesbury that she held two councils at Devizes, one about the 1st of April (Mid-Lent), and one at Whitsuntide (7-14 June). The latter council was held on the return of the envoys who had been despatched, after the former one, to request Geoffrey of Anjou to come to his wife's assistance. Geoffrey had replied that the Earl of Gloucester must first come over to him, and the earl accordingly sailed from Wareham about the end of June. It is most probable that he went there straight from Devizes, in which case he was not at Oxford after the beginning of June. In this case, that is the latest date at which the charter can have passed. Although the original of this charter cannot, like its predecessor of the previous year, be traced down to this very day, we have the independent authorities of Dugdale and of another transcriber for the fact that it was duly recorded in the Great Coucher of the duchy.[511] If the missing volume, or volumes, of that work should come to light, I cannot entertain the slightest doubt that this charter will be found there entered. Collateral evidence in its favour is forthcoming from another quarter, for the record with which, as I shall show, it is so closely connected that the two form parts of one whole, has its existence proved by cumulative independent evidence.
