There are those who see in the derivation of the name "Runnymede" an ancient use of the meadow as a place of council. This is, of course, mere conjecture, but at any rate it was, at this season of the year, a large, dry field, in which a considerable force could encamp. The Barons marched along the old Roman military road, which is still the high-road to Staines from London, crossed the river, and encamped on Runnymede. Here the Charta was presented, and probably, though not certainly, signed and sealed. The local tradition ascribes the site of the actual signature to "Magna Charta" island--an eyot just up-stream from the field, now called Runnymede, but neither in tradition nor in recorded history can this detail be fixed with any exactitude. The Charta is given as from Runnymede upon the 15th June, and for the purpose of these pages what we have to note is that these two months of marching and fighting had ended upon the strategic point of Staines, and had clearly shown its relation to Windsor and to London. In the short campaign that followed, during which John so very nearly recovered his power, the capital importance of Windsor reappears. Louis of France, to whom the Barons were willing to hand over what was left of order in England, had occupied all the south and west, including even Worcester, and, of course, London. In this occupation the exception of Dover, which the French were actively besieging, must be regarded as an isolated point, but _Windsor_, which John's men held against the allies, threw an angle of defence right down into the midst of the territory lost to the Crown. Windsor was, of course, besieged; but John's garrison, holding out as it did, saved the position. The King was at Wallingford at one moment during the siege; his proximity tempted the enemy to raise the siege, to leave Windsor in the hands of the royal garrison, and to advance against him, or rather to cut him off in his advance eastward. They marched with the utmost rapidity to Cambridge, but John was ahead of them: and before they could return to the capture of Windsor he was rapidly confirming his power in the north and the east. It must not be forgotten in all this description that Windsor was helped in its development as a fortress by the presence to the south of the hill of a great space of waste lands. These waste lands of Western Europe, which it was impossible or unprofitable to cultivate, were, by a sound political tradition, vested in the common authority, which was the Crown.
