In the afternoon they succeeded in making a lodgment in some pucka cook-houses inside our abattis, and began to use a crowbar, which was distinctly heard. We made a hole through to them from above, through which they fired, injuring no one; but on our throwing down some hand grenades, they fled across the road, two being shot by the officers who were watching from above. The 13th, 71st, and 48th sepoys all behaved well, and the manner in which the outposts were held, was beyond all praise. The uncovenanted distinguished themselves greatly. We had fortunately only four men killed, and some twelve wounded: Captain Forbes, Lieutenant Grant, Lieutenant Edmonstone, and Mr. Hely, were wounded. All were under arms from eight in the morning until eight at night, and greatly fatigued and worn out.

July 21st.—All very quiet during the night. The enemy were probably fatigued with their exertions yesterday, for throughout the night only a few round shot were thrown in. About 10 A.M. the enemy lodged themselves in some force in the low buildings between the Seikh courtyard and Mr. Gubbins's post, but were driven out by a few shells, and were fired on by the officers of the brigade mess, as they ran across a small lane: they did not attempt to reoccupy the position during the day. About 12 o'clock, Major Banks was killed by a musket-shot through the head, as he was reconnoitring from the top of an outhouse. Mr. Gubbins's garrison was fired on smartly during the morning, and many round shot were sent into Mr. Gubbins's house; the garrison of which had many alarms during the day. Painful boils very prevalent. A dreadful stench pervaded the place in consequence of the number of dead horses and bullocks, which, lying direct under the fire of the enemy, we were unable to remove. Excessive heat, and several cases of cholera. Great fatigue; no news. Poor Dr. Brydon severely wounded in Mr. Gubbins's house. Two Europeans killed, and two wounded; also one of the 13th sepoys.

July 22nd.—Very heavy rain began to fall at 1 A.M., and continued till 8 A.M., when it cleared off. During the heavy rain, the enemy only fired slightly. After 8 A.M. it became more brisk, and they fired several round shot, but were not very active during the forenoon. Cholera still prevalent. Our numerical strength much diminished, as we had had 151 casualties in the 32nd Regiment alone. The enemy moved the 8-inch howitzer from its old position, and brought it across the river by elephants, with a tumbril behind it. Up to this date, we had no intelligence of any kind from any quarter, and, indeed, we had received none since the 27th ultimo. Many messengers were sent with letters, but not a single line did we receive in reply. A letter was sent off to Cawnpore to-day, and conveyed by a man named Ram Singh, a Seikh subadar of the 63rd Native Infantry. The enemy steadily loop-holing all the houses close round about, and evidently up to some new attempt at our position.

At dusk heavy rain; we got out a strong working party, and opened our large powder magazine, and after much labour and exertion got up 150 barrels out of the 240 we had buried. The night was pitch dark, and the rain fell heavily, and the work being outside of our entrenchment, over which all the barrels had to be handed out of mud knee deep, rendered the work fearfully fatiguing. Many of the officers and civilians worked for five hours at this work. Only a few shots during the night. Boils still very prevalent. A Seikh from the cavalry deserted. One or two cases of cholera. Mortification having set in, Mr. Hely's arm was amputated.

The buildings outside Mr. Gubbins's position were shelled at sunset, and after we had driven the enemy out, we made a sortie through the wall (in which we had cut a large hole), and rushed out and examined the houses in which the enemy had been. We failed to find any trace of mining. We lost one man of the 32nd, killed. Mrs. Dorin was killed dead by a musket ball in Mr. Gubbins's house to-day.

July 23rd.—Very heavy rain during the night. About 2 A.M. the enemy sounded the "turn out," and at 3 the "assembly." About 1 A.M. a native pensioner, who left us on the 27th to gain information, came in, and said he had been confined by the enemy thirteen days, but had been to Cawnpore and left it two days ago,—that a British force with twelve guns was there; that they had fought three times with the Nana's troops, and had completely beaten them, taking many guns, and that they were crossing the river preparatory to advancing to our assistance. He stated that he had not brought a letter, for fear of being detained by the enemy; he vouched to the truth of his statement, declined a pecuniary reward, and was urgent to go back quickly while it rained heavily and all was quiet comparatively. He left in two hours, taking a small note for the officer commanding the forces.

At daylight there were fewer of the enemy than we had yet seen about, and those less active; though they still fired smartly all around. Stench from dead animals in some parts dreadful; as we had very few servants of any kind and our fighting men were so few and so harassed, that we were helpless to bury them. Heavy showers both day and night, keeping the garrison constantly drenched to the skin, and making all most uncomfortable; particularly as few had a change of clothes. Enemy fired slackly during the afternoon. Cannonaded their bridge of boats, which was broken by our 18-pounder shot. Several cases of smallpox. Sick and wounded much crowded. The upper story of the hospital being under fire of round shot, the wounded were, from the commencement of the siege, confined to the ground floor, which with difficulty contained their beds. At night it rained hard; and in spite of all difficulties, we succeeded in getting up the remaining ninety barrels of powder, and safely deposited them in the centre of our position. A false alarm about 12 o'clock at night, that the enemy had got into the churchyard.

July 24th.—Morning fair and cloudy. The enemy endeavoured to repair the bridge of boats, but were prevented by the fire of our 18-pounder. The heat and stench terrible, and the flies were beyond endurance, contesting every particle of food with us, and preventing all attempts at rest during the day. Only a few round shot thrown, but the enemy actively at work about forty yards from the Redan battery, in a deep trench. Advantage taken of the temporary lull to repair some of our defences, which had sunk a great deal in consequence of the heavy rain; but our men, reduced in numbers and harassed to death day and night, were not capable of any prolonged exertion. Every possible effort was made to grind wheat, and from twenty-five to thirty hand-mills were kept steadily at work, producing an average of twenty maunds of flour daily. The 48th Regiment Native Infantry have had seven, and the 71st Regiment, upwards of fifty desertions, since the commencement of the siege.

About dusk, the enemy, for the first time, sent in many shells; which, however, caused no loss, fortunately. The commissariat department busy with the stores, getting ghee up from the Round House; while a fatigue party of officers, under Captain Radcliffe, threw up earth, and heightened the traverse across the road, near the Post-office gate. Lieutenant Hutchinson, of the Engineers, accompanied by Lieutenant Birch, crept down in the dark, and examined, as well as they could, the enemy's works in the immediate vicinity of the Redan. Night dark and cloudy.
