That these Dene Holes were used as hiding-places when the sails of the Danish Vikings appeared on the horizon is probable enough, but originally they were chalk quarries—some very ancient—for British coins have been found in them. The existence of old lime-kilns near the Chislehurst caves places their origin beyond a doubt. Chalk was largely exported in early times from the Thames to Zealand, whence it was passed through the Low Countries and used in dressing the fields. Altars to Nethalennia, the patroness of the chalk quarries, have been found in the sand on the coast of Zealand; some bear votive inscriptions from dealers in British chalk, and Pliny, writing of the finer quality of chalk (argentaria) employed by silversmiths, obtained from pits sunk like wells, with narrow mouths, to the depth of a hundred feet, whence they branch out like the adits of mines, adds, "Hoc maxime Britannia utitur." [Footnote: Roach Smith, Collectanea Antiqua, vi. p. 243, "British Archæological Assoc. Journal," N.S., ix.-x. (1903 and 1904).]
In Cornwall, moreover, there are what are locally called fogous. These are either excavated in the rock with passages leading to the sea or to houses, or else they are built of stone slabs standing erect, parallel and covered with other slabs leading to chambers similarly constructed, and all buried under turf or sand. Of the former description there is a very interesting example at Porthcothan in S. Ervan; of the latter the most remarkable is at Trelowaren. The former may have been excavated by smugglers. An interesting account of the excavation of two caves at Archerfield, in Haddingtonshire, is given in the Proceedings of the Society of Antiquaries of Scotland for 1909. Both caves are natural, but one had been walled up in front, with a doorway and window and with oven; both had paved hearths in the centre, and there was evidence that they had been tenanted some time after the Roman occupation of Britain, as among the fragments of pottery found was some Samian ware. It would appear that both had been inhabited simultaneously, but not consecutively, for a lengthy period, and no doubt can exist that they were mere rock refuges. In a note to the article we read: "On the coast of Island Magee (Ireland) there is a cave, south of the Gobbins, which has been frequently used as a place of refuge. So late as 1798 it was inhabited by outlaws, who constructed a kind of fortification at the entrance, the remains of which still exist." [Footnote: Cree (J. R.), "Excavation of Two Caves," in "Proceedings of the Soc. of Arch. of Scotland," Edin., 1909, vol. xliii.]
A cave in the Isle of Egg, one of the Hebrides, has a very narrow entrance, through which one can creep only upon hands and knees, but it rises steeply within and soon becomes lofty, and runs into the bowels of the rock for 225 feet. The stony, pebbly bottom of this cavern was for long strewn with the bones of men, women and children, the relics of the ancient inhabitants of, the island, two hundred in number, of whose destruction the following account is given. "The Macdonalds, of the Isle of Egg, a people dependent on Clanranald, had done some injury to the Lord of Macleod. The tradition of the isle says that it was by a personal attack on the chieftain, in which his back was broken; but that of the two other isles bears that the injury was offered by two or three of the Macleods, who, landing upon Egg and behaving insolently towards the islanders, were bound hand and foot, and turned adrift in a boat, which the winds safely conducted to Skye. To avenge the offence given, Macleod sailed with such a body of men as rendered resistance hopeless. The natives, fearing his vengeance, concealed themselves in the cavern; and, after strict search, the Macleods went on board their galleys after doing what mischief they could, concluding the inhabitants had left the isle. But next morning they espied from their vessels a man upon the island, and immediately landing again, they traced his retreat by means of a light snow on the ground to the cavern. Macleod then summoned the subterranean garrison, and demanded that the inhabitants who had offended him should be delivered up. This was peremptorily refused. The chieftain thereupon caused his people to divert the course of a rill of water, which, falling over the mouth of the cave, would have prevented his purposed vengeance. He then kindled at the entrance of the cavern a large fire, and maintained it until all within were destroyed by suffocation." [Footnote: Lockhart's "Life of Sir Walter Scott," Edin., 1844, p.285.]
A no less horrible deed was committed during the campaign of Essex against the Irish rebels in 1575. This shall be given in the words of Froude. [Footnote: "Hist. of England," 1870, x. p. 527 et seq.]
"On the coast of Antrim, not far from the Giant's Causeway, lies the singular island of Rathlin. It is formed of basaltic rock, encircled with precipices, and is accessible only at a single spot. It contains an area of about 4000 acres, of which a thousand are sheltered and capable of cultivation, the rest being heather and rock. The approach is at all times dangerous; the tide sets fiercely through the strait which divides the island from the mainland, and when the wind is from the west, the Atlantic swell renders it impossible to land. The situation and the difficulty of access had thus long marked Rathlin as a place of refuge for Scotch or Irish fugitives, and besides its natural strength it was respected as a sanctuary, having been the abode at one time of Saint Columba. A mass of broken masonry on a cliff overhanging the sea is a remnant of the castle, in which Robert Bruce watched the leap of the legendary spider. To this island, when Essex entered Antrim, Macconnell and the other Scots had sent their wives and children, their aged, and their sick, for safety. On his way through Carrickfergus, when returning from Dublin, the Earl ascertained that they had not yet been brought back to their homes. The officer in command of the English garrison was John Norris, Lord Norris's second son. Three small frigates were in the harbour. The sea was smooth; there was a light and favourable air from the east; and Essex directed Norris to take a company of soldiers with him, cross over, and kill whatever he could find. The run up the Antrim coast was rapidly and quietly accomplished. Before an alarm could be given the English had landed, close to the ruins of the church that bears Saint Columba's name. Bruce's castle was then standing, and was occupied by a detachment of Scots, who were in charge of the women. But Norris had brought cannon with him. The weak defences were speedily destroyed, and after a fierce assault, in which several of the garrison were killed, the chief who was in command offered to surrender if he and his people were allowed to return to Scotland. The conditions were rejected; the Scots yielded at discretion, and every living creature in the place, except the chief and his family, who were probably reserved for ransom, were immediately put to the sword. Two hundred were killed in the castle. It was then discovered that several hundred more, chiefly mothers and their little ones, were hidden in the caves about the shore. There was no remorse—not even the faintest perception that the occasion called for it. They were hunted out as if they had been seals or otters, and all destroyed. Surleyboy and the other chiefs, Essex coolly wrote, 'stood upon the mainland of Glynnes and saw the taking of the island, and was likely to have run mad for sorrow, tearing and tormenting himself, and saying that he had there lost all that ever he had.' According to Essex's own account, six hundred were thus massacred. He described the incident as one of the exploits with which he was most satisfied; and Queen Elizabeth in answer to his letters bade him tell John Norris, 'the executioner of his well-designed enterprise, that she would not be unmindful of his services.'" The neighbourhood of Gortyna in Crete has a mountain labyrinth, and during the revolt of the Cretans against the Turks in 1822-28, the Christian inhabitants of the adjacent villages, for months together, lived in these caves, sallying forth by day to till their farms or gather in their crops, when it was safe so to do. None could approach within range of the muskets pointed from the loopholes at the entrance without being immediately shot down; nor could either fire or smoke suffocate or dislodge the inmates, as the caves have many openings.
Less happy were the Christian refugees in the cave of Melidoni. In 1822, when Hussein Bey marched against the neighbouring village, the inhabitants, to the number of three hundred, fled to the cave, taking their valuables with them. Hussein ordered a quantity of combustibles to be piled at the entrance and set on fire. The poor wretches within were all smothered. The Turks waited a few days, and then entered and rifled the bodies. A week later, three natives of the village crept into the cavern to see what had become of their relatives. It is said that they were so overcome by the horror of what they witnessed, that two of them died within a few days. Years after, the Archbishop of Crete blessed the cavern, and the bones of the victims of Turkish barbarity were collected and buried in the outer hall, which has in its centre a lofty stalagmite reaching to the summit, and the walls on all sides are draped with stalactites.
We must not pass over without a word the treatment of the Arabs in Algeria by the French troops, when General Lamorcière suffocated the unfortunate refugees in the caves whither they had fled, in the same way as Caesar's general had suffocated the Gauls.
CHAPTER IV
CLIFF REFUGES
I have divided Refuges into two classes—those that have been burrowed under the soil, and those that open in the face of a cliff. Occasionally they run one into another, and yet they materially differ. The first have their entrances elaborately concealed, whereas the latter are bare to the face of day, and no concealment is possible or attempted. Those who had recourse to the first trusted in being able, should the entrance be discovered or betrayed, to defend themselves by various devices, whereas those who resorted to the latter relied on their inaccessibility.
