the border by binding all the barons of the district in a sworn mutual alliance for its defence.[903] The attempt was not very successful; the border-warfare went on in much the same way as of old; but it was not till the summer of 1184 that it grew serious enough to call for Henry’s personal intervention, and then a march to Worcester sufficed to bring Rees of South Wales once more to his feet.[904] [893] Ann.

According to the _Brut_ (as above) Henry first “moved an army with extreme haste, and came to Rhuddlan, and purposed to erect a castle there, and stayed there three nights. After that he returned into England, and collected a vast army,” etc. Following this, Mr. Bridgeman (_Princes of S. Wales_, p. 48) and Mr. Eyton (_Itin. Hen. II._, pp. 79, 82) divide the Welsh campaign of 1165 into two, one in May and the other in July. Neither the Ann. Cambr. nor Gerald, however, make any mention of the Rhuddlan expedition. [896] Ann.
