Before the castle was built this spot was probably an inaccessible peak of naked rock; the top, however, has been blown away to afford space for military occupation, leaving height enough to afford a formidable scarp of natural rock towards the land as the basement of the artificial rampart; towards the sea, an abrupt precipitous cliff, inaccessible to man, descends perpendicularly into the deep water.
The fort constructed upon the table of this peninsular rock was, up to a certain point, admirably adapted for security and strength. But that abrupt and lonely precipitousness of inaccessible circuit, which to the unlearned eye presented so imposing a picture of invulnerable strength, was in fact the radical defect of the position, which made it impossible to secure it against the means and measures of modern war. The great strength of modern fortification consists certainly in the glacis, or in that smoothly sloping mound which conceals and covers the rampart to the very chin, yet is severed from it by a deep and impassable ditch, screening it from every injury, even by the heaviest and most numerous ordnance, whilst its own gradual slope is swept by a rain and hail of cannon-balls, grape shot, and musketry, both from its own parapet and that of the superior rampart. But to construct this, ample space is necessary, and consequently for a rocky peak like Scylla, joined to the land by a narrowing isthmus, this work, so indispensable to durable strength, was totally unattainable.
The strength, then, of the Castle of Scylla lay briefly in this, that its reduction required the bringing against it of heavy artillery, capable of beating down the rampart that fronted the land.
So much for the castle which I now beheld, and which, surrounded with enemies by sea and land, and cut off from all connection with any friendly force, stood up boldly in the midst of that sapphire sea and unfurled the three-coloured flag of national defiance.
I shall now briefly describe the circumstances and things by which it was at this time surrounded, not so much on account of any historical importance attaching to this little siege, as because the classic associations and natural beauties of the scene consecrate it to memory, and its local form subjected all these operations to the eye, like some warlike spectacle in the theatre of the gods.
If we can fancy ourselves within the castle and looking over the isthmus in the direction of the land, behind us and almost all round us is the sea. On the left hand is the beach and town of Scylla. On the right the bold and mountainous shore takes a gradual sweep, till over a space of sea it looks down upon our right flank. Here Sir Sidney Smith has established a battery and hoisted the English colours.
Immediately in front, from the base of the isthmus, rises a steep cliff, whose brow, divided into several distinct hills, overlooks the castle at the distance of some five or six hundred yards. These heights have a surface very spacious, rising very gradually from the cliff towards the steeps of the Superior Mountains. Farms, vineyards, gardens, and country houses occupy and intersect this sloping headland. But the head of each hill or cliff looking upon the castle has been kept bare, probably with a view to defence, though unfortunately the same precaution had not been observed with respect to the ground nearer the foot of the cliff, and looking very close upon the main rampart; for there, for marine convenience, a little suburb had been suffered to rise, and it was behind the mask of one of these houses that the breaching battery was at last erected.
Beyond that vine-clad esplanade or level district which rose very gradually from the brow of the cliff, the heights, still clothed with cultivation, ascended more steeply towards the summit of that vast range of mountains, which makes this trend of coast so bold, imperious, and pre-eminently beautiful.
It was partly upon, and partly still above, these steeper slopes that the besieging army bivouacked, as the nearer ground would have made them liable to annoyance from the guns of the castle.
All the necessary communication with the army from Sicily and from the sea was by a rugged mountain path formed upon the side of an awful ravine, whose embouchure opened upon the beach between the town and castle.
