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 10A.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.
