Nature has done much for the fortification of Aculcho. Imagine a hill of sand-stone, nearly surrounded by a loop of the river Koisu – a miniature peninsula, in short, connected with the continent by a narrow neck of land – provided with three natural terraces, accessible only by a small rocky path, whose entrance is fortified and defended by 500 resolute Tshetshen warriors. A few artificial parapets and intrenchments, some stone huts, and several excavations in the sand rock, where the besieged found shelter from shot and shell, complete the picture of the place before which Grabbe and his column sat down. At first they hoped to reduce it by artillery, and bombs and congreve rockets were poured upon the fortress, destroying huts and parapets, but doing little harm to the Tshetshens, who lay close as conies in their burrows, and watched their opportunity to send well-aimed bullets into the Russian camp. From time to time, one of the fanatical Murides, of whom the garrison was chiefly composed, impatient that the foe delayed an assault, rushed headlong down from the rock, his shaska in his right hand, his pistol in his left, his dagger between his teeth; causing a momentary panic among the Cossacks, who were prepared for the whistling of bullets, but not for the sudden appearance of a foaming demon armed cap-à-pie, who generally, before they could use their bayonets, avenged in advance his own certain death by the slaughter of several of his foes, whilst his comrades on the rock applauded and rejoiced at the heroic self-sacrifice. The first attempt to storm was costly to the besiegers. Of fifteen hundred men who ascended the narrow path, only a hundred and fifty survived. The Tshetshens maintained such a well-directed platoon fire, that not a Russian set foot on the second terrace. The foremost men, mown down by the bullets of the besieged, fell back upon their comrades, and precipitated them from the rock. General Grabbe, undismayed by his heavy loss, ordered a second and a third assault; the three cost two thousand men, but the lower and middle terraces were taken. The defence of the upper one was desperate, and the Russians might have been compelled to turn the siege into a blockade, but for the imprudence of some of the garrison, who, anxious to ascertain the proceedings of the enemy's engineers – then hard at work at a mine under the hill – ventured too far from their defences, and were attacked by a Russian battalion. The Tshetshens fled; but, swift of foot though they were, the most active of the Russians attained the topmost terrace with them. A hand-to-hand fight ensued, more battalions came up, and Aculcho was taken. The victors, furious at their losses, and at the long resistance opposed to them, (this was the 22d August,) raged like tigers amongst the unfortunate little band of mountaineers; some Tshetshen women, who took up arms at this last extremity, were slaughtered with their husbands. At last the bloody work was apparently at an end, and search ensued amongst the dead for the body of Chamyl. It was nowhere to be found. At last the discovery was made that a few of the garrison had taken refuge in holes in the side of the rock, looking over the river. No path led to these cavities; the only way to get at them was to lower men by ropes from the crag above. In this manner the surviving Tshetshens were attacked; quarter was neither asked nor given. The hole in which Chamyl himself was hidden held out the longest. Escape seemed, however, impossible; the rock was surrounded; the banks of the river were lined with soldiers; Grabbe's main object was the capture of Chamyl. At this critical moment the handful of Tshetshens still alive gave an example of heroic devotion. They knew that their leader's death would be a heavy loss to their country, and they resolved to sacrifice themselves to save him. With a few beams and planks, that chanced to be in the cave, they constructed a sort of raft. This they launched upon the Koisu, and floated with it down the stream, amidst a storm of Russian lead. The Russian general doubted not that Chamyl was on the raft, and ordered every exertion to kill or take him. Whilst the Cossacks spurred their horses into the river, and the infantry hurried along the bank, following the raft, a man sprang out of the hole into the Koisu, swam vigorously across the stream, landed at an unguarded spot, and gained the mountains unhurt. This man was Chamyl, who alone escaped with life from the bloody rock of Aculcho. His deliverance passed for miraculous amongst the enthusiastic mountaineers, with whom his influence, from that day forward, increased tenfold. Grabbe was furious; Chamyl's head was worth more than the heads of all the garrison: three thousand Russians had been sacrificed for the possession of a crag not worth the keeping.
After the fall of Aculcho, Chamyl's head-quarters were at the village of Dargo, in the mountain region south of the Russian fort of Girselaul, and thence he carried on the war with great vigour, surprising fortified posts, cutting off convoys, and sweeping the plain with his horsemen. Generals Grabbe and Golowin could not agree about the mode of operations. The former was for taking the offensive; the latter advocated the defensive and blockade system. Grabbe went to St Petersburg to plead in person for his plan, obtained a favourable hearing, and the emperor sent Prince Tchernicheff, the minister at war, to visit both flanks of the Caucasus. Before the prince reached the left wing of the line of operations, Grabbe resolved to surprise him with a brilliant achievement; and on the 29th May 1842, he marched from Girselaul with thirteen battalions, a small escort of mounted Cossacks, and a train of mountain artillery, to attack Dargo. The route was through forests, and along paths tangled with wild flowers and creeping plants, through which the heavy Russian infantry, encumbered with eight days' rations and sixty rounds of ball-cartridge, made but slow and painful progress. The first day's march was accomplished without fighting; only here and there the slender active form of a mountaineer was descried, as he peered between the trees at the long column of bayonets, and vanished as soon as he was observed. After midnight the dance began. The troops had eaten their rations, and were comfortably bivouacked, when they were assailed by a sharp fire from an invisible foe, to which they replied in the direction of the flashes. This skirmishing lasted all night; few were killed on either side, but the whole Russian division were deprived of sleep, and wearied for the next day's march. At daybreak the enemy retired; but at noon, when passing through a forest defile, the column was again assailed, and soon the horses, and a few light carts accompanying it, were insufficient to convey the wounded. The staff urged the general to retrace his steps, but Grabbe was bent on welcoming Tchernicheff with a triumphant bulletin. Another sleepless bivouac – another fagging day, more skirmishing. At last, when within sight of the fortified village of Dargo, the loss of the column was so heavy, and its situation so critical, that a retreat was ordered. The daring and fury of the Tshetshens now knew no bounds; they assailed the troops sabre in hand, captured baggage and wounded,
