A Kulassy of Capt. Maule's has just come in from the Kohistan half naked: he reports, that the Kohistanees are all up; that Maule and Wheeler were killed at Kar Durrah, and that they were overpowered.

This day Lieut. Gordon, of the 37th, was killed; Capt. Swayne, 44th, ditto; Lieut. Walsh, of the Shah's service, wounded in the thigh; Hallahan, 44th, in the shoulder; Warren, 54th, wounded; Capt. Robinson and four men, 44th, killed, and sixteen wounded.

The cavalry had brought in six wounded, and had thirty-one missing at 5 o'clock. The 5th cavalry went up to the gate of the Shah bagh in gallant style; but it was shut too quickly for them to get in. Hamilton's horse shot under him in the ditch under the gate.

At tea-time we had an alarm, and very smart firing like a feu de joie; but it was a false alarm. I believe no enemy was seen: it occurred on the rampart near to Sale's bastion.

After we had, as we thought, settled poor Sturt for the night, between 8 and 9 o'clock Capt. Lawrence came to see him and ask his advice. Sturt had wished to have communicated with the General on the defence of the cantonments, and, ill as he was, he had written a letter to him; but thinking that advice from so young an officer might not be relished, he, notwithstanding my remonstrances on the subject, tore it up. About 10 o'clock, Lieut. Eyre, Deputy Commissary of Ordnance, and Capt. Warburton, the Shah's Topshee Bashee, came; and as they had received information that there are men posted outside the gate of the captured fort, with matchlocks all ready, the plan in agitation of blowing open the gate with a bag of powder would not answer: they, therefore, with Sturt, decided on getting the two nine-pounders into the bastion, and on setting to work forthwith to cut the embrasures to fit them; and between 2 and 3 o'clock in the morning was fixed upon as the time to commence playing on the fort to breach it, and at the same time to throw in a proportion of shells to create confusion. The place to be taken by assault. If this does not succeed, we shall probably have to retreat to Jellalabad. Sturt strongly advises the troops being all thrown into the Bala Hissar, and the cantonments being abandoned until we get up reinforcements; but the cry is, how can we abandon the cantonments that have cost us so much money?

The enemy's force are estimated at from 1500 to 2000. Brig. Shelton is expected in from the Bala Hissar, where they are said to be short of provisions. Here we got six seers of ottah for the rupee yesterday, but to-day none is procurable. The servants are to get half rations from the commissariat to-morrow.

At the Bala Hissar two companies!!! were warned for service under Capt. Corri, 54th, for the purpose of entering the town to cause a diversion during the expected attack which it was understood there was about to be made from cantonments. However it was, as usual, only one of the theoretical plans so often talked of, and so little practised. Conolly, Troup, and Hay had gone there for the purpose of assisting with counsel; but there was "great cry and little wool," and nothing was done.

The supplies are become very limited, and it becomes a question how the troops and Horse Artillery horses are to be fed: to-day there were only three days' provisions left; but owing to the great exertions of Capt. Kirby, Acting Assistant Commissary-General, a very large quantity was laid in, Damel Khan and Timor Khan, two Armenian merchants, being very instrumental in procuring them. Immediately in the neighbourhood of the Bala Hissar were fields of wheat stretching out for many acres; the wheat being the second crops, and some half a foot high, was found to be excellent food for the cattle: the groves also, in the vicinity, were all cut down for firewood, which, as long as it lasted, was very liberally distributed to the troops by the King.

5th.—At 5 o'clock A.M., no reinforcement having gone to the assistance of Lieut. Warren, although promised by 2, that officer vacated the Commissariat fort. No blame can attach to him, but much to those who withheld aid. The enemy took possession, depriving us of our only means of subsistence. Nor was this all the mischief: it gave both confidence and much plunder to the enemy, and created great disgust amongst the Europeans, who lost all their rum; a worse loss was all the medical stores, sago, arrow-root, wine, &c . for the sick.

The men in cantonments were employed all day, the guns and mortars throwing shot and shell at the Mahommed Shureef's fort; Major Swayne being ordered with a very insufficient force to attack it, only two companies with two Horse Artillery guns, under Lieut. Eyre. The latter were ordered to be placed on the Kohistan road, outside the gate of cantonments, and to keep up a heavy fire on the fort; whilst Major Swayne was to advance rapidly on the fort, and blow open the gate with a bag of powder. Lieut. Eyre obeyed his orders; but his ammunition was all expended before the arrival of Major Swayne's party, who, instead of advancing, had, on a fire of matchlocks being opened from the fort, taken cover under some walls from the heavy fire of the enemy; and having expended all their ammunition ineffectually, the whole had to retire with some loss of men and horses. This was the only opportunity that offered of retrieving our loss. The enemy were busied in hundreds all day in carrying off our stores, all which we plainly saw from cantonments. The troops retired by order of Gen. Elphinstone, to my no small surprise, for the enemy had begun to run out from a broken bastion; but when they found our people retreating, they took courage, and no more left the fort, on which shot and shell kept playing all day. After stating this, it is unnecessary to add that Sturt's suggestions had not been acted on.
