To justify these inferences, a more detailed examination of the evidence available will be necessary. The earliest meeting between John and the baronial leaders, all authorities are agreed, took place on Monday, 15th June, probably in the early morning. The barons undoubtedly came to the conference provided with an accurate list of those grievances which they were determined to have redressed. On the previous 27th of April the rebels had sent a written Schedule to the King, along with a demand that he should signify his acceptance by affixing his seal;[35] they are not likely to have been less fully prepared on 15th June. ----- Footnote 35: R. Wendover, III. 298. ----- John, on his part, would naturally try a policy of evasions and delays; and, when these were clearly useless, would then endeavour to secure modifications of the terms offered. These tactics met with no success. His opponents demanded a plain acceptance of their plainly expressed demands. Before nightfall, John, overawed by their firmness and by the numbers of the armed force behind them, was constrained to surrender. Leaving minor points of detail to be subsequently adjusted, he provisionally accepted the substance of the long list of reforms put before him by the barons, on the understanding that they would renew their allegiance and give him some security that they would keep the peace. In proof of this bargain, the heads of the agreement were rapidly engrossed on parchment to the number of forty-nine, and the great seal was impressed on the wax of the label, where it may still be seen.[36] ----- Footnote 36: In the British Museum. See _infra_ under Part V. ----- The parchment containing these Articles of the Barons may have been the identical Schedule actually prepared by the rebel leaders previous to the meeting; but, more probably, it was written out at Runnymede during the conference on the 15th (or between two conferences on that day) by one of the clerks of the royal Chancery. This is more in keeping with its heading (written in the same hand, and apparently at the same time as the body of the deed), _Ista sunt capitula quae barones petunt et dominus rex concedit_.
