The Cossacks, on the hills beyond Inkerman, have nearly disappeared and there are no indications that they intend to occupy the hills again, or construct batteries there as was supposed. The greatest secrecy is observed respecting our future operations; strict orders have been given that officers and others are not to give information regarding our works and movements but to those entitled to demand it. I was on trench duty last night when it froze hard, with bitter cutting wind, drifting the snow into our eyes and filling the trenches; but the sun shone out in the morning and the wind fell. The day was clear and cold, and the warm clothing and long boots enabled us to bear the severity of the weather, which would have been fatal to many, had we been in the same state as our comrades on whom winter fell with all its rigour, while they had nothing to wear but their old regimental clothing. We are now well secured with long boots, fur caps and warm jackets. As the day was clear, I could see the Russians plainly, in spite of the dazzling effect of the snow and cold. The bridge of boats across the creek, from the government buildings to the other side of the town, was crowded with men, who were busily engaged passing across supplies and rolling barrels to the other side, shewing that there is a centre of supply or depôt in the government buildings behind the Redan and opposite the fire of our batteries. Several lighters under sail and full of men were standing over from one side of the harbour to the other, and boats manned with crews dressed in white were tugging scows laden with stores to the south side of the town. A small steamer was also very active, puffing and splurting about the harbour in all directions, furrowing the surface of the water, which was as smooth as glass, so completely is the harbour land-locked—the men-of-war with their white ensigns and St. Andrew's cross, lying in a line at the north side. The masts of three vessels could be seen plainly above the buildings; further away to the right toward Inkerman the white houses and barracks shone brightly in the sun, and the bells of the churches were ringing out clearly in the frosty air; the tall houses running up the hillside, with its massive, public buildings, gave Sebastopol rather an imposing appearance. There was not a soul to be seen in the streets except soldiers running across the open space from one battery to another, relieving guards or posting sentries. Outside the town the eye rests on walls of earth piled up ten or twelve feet high and twenty feet thick, with embrasures, in which I could see the muzzles of the guns pointing toward our batteries; those works are of tremendous strength, with a very deep and broad ditch in front. Round the suburbs of the town are broken-down, white-washed cottages, the roofs of which are all gone, the doors off and the windows out, the walls are left standing at a certain distance from the batteries with holes made in them so that the guns can cover their object; they are also used for sharpshooters.

The picture of misery presented by these suburbs is very striking, in most instances the destruction has been caused by our shot, and the houses all round the Flagstaff and Garden batteries have been blown into heaps of rubbish and mortar. There have been a great many shells thrown by the Russians to-day from a mortar battery towards the sea, projecting the shells into the air every half minute or so across a hill in front of it, so as to annoy our working party, who were engaged in throwing up a trench towards the Quarantine fort. The white smoke rushing into the air expands into rings; then follows the heavy dull report; then comes the shrill whistle of the shell travelling through the air as it describes its curve, and descends with great velocity, increasing as it reaches the ground, sometimes sinking deep into the earth, tearing it up with the explosion, to the destruction of those around. It is a most unpleasant reflection when we see a whistling Dick coming in the air, and run out of its way behind a traverse. To how many families have they carried deep sorrow and mourning. The smoke clears away, then men gather around one who moves not, they bear him away on a stretcher, and a small mound of fresh earth marks for a little time the resting-place of the soldier, whose wife, mother, children, or sisters are left destitute of all happiness, save the memory and the sympathy of their country. Who will let the inmates of that desolate cottage in England, Ireland, or Scotland, know of their bereavement? However there goes another shell which does nothing but knock up a cloud of earth and stones.

After being relieved, we marched to our gloomy camp under a heavy fire from the enemy; but my hut was not so gloomy as the men's tents, it was warm and comfortable, my comrade had a little fire, keeping my coffee and fried biscuits warm, with a cotton rag dipped in pork fat as a substitute for a candle.

February 25th. The 17th Regiment was roused at two o'clock this morning and marched down to reinforce the covering party in the trenches. The Russians commenced one of the most furious cannonades we have heard since the siege began. The whole of the Russian batteries from our left opened with immense force and noise, the Redan, Garden and Malakoff batteries began firing round shot and shell. Our second parallel and twenty-one gun batteries were exposed to the weight of this most terrible fire, which shook the very earth and lighted up the sky with incessant lightning flashes for two hours, under cover of which a very strong sortie was made, and for an hour the musketry rolled incessantly with vigour enough for a general engagement. As soon as the fire opened, an aide-de-camp rode to our lines and gave the order for the 17th, 57th, and 20th Regiments to march to the trenches, and in less than five minutes these three regiments were moving in double time toward the trenches. On arrival, we found that the covering party had succeeded in driving the enemy from our trenches. We then returned to our camp and lay down for a couple of hours. The Russians had made a sortie on the French lines at the same time, and were also driven back with great loss.

At the request of General Ostensacken, an armistice was granted from twelve till one o'clock to-day, to enable the Russians to bury their dead. There was not much firing this morning; at twelve o'clock white flags were run up on the batteries on both sides, and immediately afterwards a body of Russians issued from the Redan, Flagstaff, and Malakoff batteries, and proceeded to carry off their dead; and our men, with the French, emerged from our batteries on a similar errand. A few Russian officers advanced about half way towards our batteries, when they were met by our officers and the French where extreme courtesy, the interchange of profound salutations and bowings marked the interview. The officers walked up and down, and skakos were raised and caps doffed politely as each came near an enemy; in the meantime the soldiers were carrying the dead and wounded off the field. About one o'clock the Russians retired inside their batteries, and immediately after the white flags were hauled down. The troops had scarcely disappeared over the parapet, when the flash and roar of a gun from the Malakoff announced that the war had begun once more, and our batteries almost simultaneously fired a gun; in a moment afterwards the popping of rifles commenced as usual on both sides.

The Cossacks about Balaklava are particularly busy throwing out their piquets and sentries all along the top of Canrobert's Hill. These sentries can see everything that goes on in the plain, from the entrance to Balaklava to the edge on which our right rests; not a horse, cart, or man can go in or out of the town, without being seen by these sentries, for they are quite visible to any person who gazes from the top of Canrobert's Hill. The works of the railway must cause these Cossacks very serious apprehensions. What can they, or do they, think of them? Gradually they see villages of white huts rise up on the hillside and in the valleys, and from the cavalry camp to the heights of Balaklava they can see line after line of wooden buildings, and can discover the tumult and bustle on Kadikoi. This may be all very puzzling; but it can be nothing to the excitement of looking at the railway trucks rushing round the hill at Kadikoi, and running down the incline to the town at the rate of twenty miles an hour. The Cossacks gallop up to the top of the hill to look at this phenomenon, and they caper about shaking their lances in wonder and excitement when the trucks disappear.

About 300 sick men were sent down to Balaklava to-day, on the ambulance mules.

The preparations for the general bombardment are progressing with great rapidity, and arrangements have been made to send up two thousand pounds of ammunition per day to the front from the harbour; about two hundred mules have been pressed into the service in addition to the railway, and the Highlanders, and Artillery horses are employed in the carriage of heavy shot and shell to the front, a duty which greatly disables and distresses them. The Guards are all down at Balaklava; some of them seem in very delicate health; a few old campaigners have attained that happy state in which no hardships or privations can have any effect on them. The silence and calm of the last few days are but the omens of the struggle which is about to be resumed very speedily for the possession of Sebastopol. The Russians are silent, because we do not impede their work; we are silent, because we are preparing for the contest, and are using every energy to bring up from Balaklava the enormous amount of projectiles and mountains of ammunition which will be required for the service of our batteries, when we open a general bombardment.

The railway has begun to render us some service in saving the hard labour attendant on the transport of shot and shell, and enables us to form a small depôt at the distance of two miles and a half from Balaklava, which is, however, not large enough for the demands made upon it, and it is emptied as soon as it is formed by parties from the regiments in front, who carry ammunition to the camp depôt, four miles further on.

The navvies work at the railway hard and honestly, with a few exceptions, and the dread of the provost marshal has produced a wholesome influence on the dispositions of the refractory. About 200 men of the Naval Brigade have been detailed to assist in the works of the railway, in order that the construction of it may be hastened as much as possible.
