On the eastern side of the Park it is continued for about 200 yards as a footpath. It is then lost under the plough; but a lane, some seven furlongs further on to the east, recovers the alignment,[34] and leads straight on to the crossing of the Darent, down just such a spur as marked the crossing of the Mole, while above us went a flanking road, marked by stunted trees, on the windy edge of the Downs. Following it thus we passed the northernmost of the two railway arches, went down the hill a mile or so, crossed the plain that was till recently marshy and difficult, and entered the village of Otford by the bridge and over the ford whereby, certainly since Edmund Ironside, and probably for many thousands of years before that, men had come to it. Indeed, here, where the Old Road falls into the valley of the Darent, its importance in recorded history, which had been growing steadily as we went eastward, was suddenly increased for us, and the cause was the reception at this point of its tributary from London. From Otford the Old Road becomes strategic. It is the road by which marched the defending forces when invasion was threatened from the Thames estuary. It becomes hierarchic; the power of Canterbury seizes it; and it becomes royal, perpetually recalling the names and at last the tyranny of the kings. The battle against the invader, the king's progress to the sea, the hold of the Church upon the land it traverses, fill all the final marches from the crossing of the Darent to that of the Stour. Something of military history as at Alton, at Farnham, and just down the Stane Street at Anstie Bury, had attached even to the earlier part of so ancient a way--but from Otford onward it is greatly emphasised. As one comes down from the chalk pit above the river one is crossing what is probably the site of Edmund Ironside's great and successful struggle with the Danes in 1016, when he defeated Canute and drove him across the river, and pursued the rout mile upon mile to Aylesford. Half a mile further down on the plain, just before you get into the village, is the field where Offa is said to have achieved the supremacy of England by the conquest of Kent in 773. It is only a doubtful bit of tradition, but it is worth recording that one more battle was fought here--as the populace believed--in the very first struggle of all--in the legendary fifth century. It is said that the Saxons were defeated here by the British, and that they also retreated towards Aylesford. Canterbury had shown its influence long before this valley. We had seen the chapels and had but just left Brasted, whose allegiance to the archbishop was old beyond all record. But from Otford onward the power of the See became peculiar and more definite. First there was the string of great palaces, Otford, Wrotham, Maidstone, Charing: Otford, Wrotham, and Charing especially, standing as they did directly upon the Old Road and created by it. We saw them all. They are in ruins.
