Adrian Hope's horse was shot dead--indeed, very few escaped injury, either to themselves or their horses.

I was one of the lucky few.

On reaching the wall of the Shah Najaf enclosure, it was found to be twenty feet high, no entrance could be seen, and there were no scaling-ladders available, so there was nothing for it but to endeavour to breach the massive wall.[3] The 24-pounders hammered away at it for some time, but proved quite unequal to the task; though only a few yards off, they made no impression whatever, and it seemed as if the attempt to take the position must be abandoned.

Peel was, therefore, ordered to withdraw his guns under cover of some rockets, which were discharged into the enclosure, and Hope was directed to retire as soon as he could collect the killed and wounded.
Captain Allgood, Sir Colin's trusted Assistant Quartermaster-General, was the bearer of the order.

He and Hope, after consulting together, determined that before the latter obeyed they would try to discover if there did not exist an opening in some other part of the walls.
Assisted by a sergeant of the 93rd, they set about their search, and actually did find a narrow gap, through which they could see that the enemy, terrified and thrown into confusion by the exploding rockets falling amongst them, were fast abandoning the building.
