The garden was held by 2,000 mutineers.  With shouts of “Remember Cawnpore,” the troops flung themselves upon them; and although the mutineers fought desperately, and the struggle was continued for a considerable time, every man was at last shot or bayoneted.

In the meantime a serious struggle was going on close by.  Nearly facing the Secunderbagh stood the large Mosque of Shah Nujeeff.  It had a domed roof, with a loopholed parapet and four minarets, which were filled with riflemen.  It stood in a large garden surrounded by a high wall, also loopholed, the entrance being blocked up with solid masonry.  The fire from this building had seriously galled Hope’s division, while engaged in forcing its way into the Secunderbagh, and Captain Peel, with the Naval Brigade, brought up the heavy guns against it.  He took up his position within a few yards of the wall and opened a heavy fire, assisted by that of a mortar battery and a field battery of Bengal Artillery; the Highlanders covering the sailors and artillerymen as they worked their guns, by a tremendous fire upon the enemy’s loopholes.  So massive were the walls that it was several hours before even the sixty-eight pounders of the Naval Brigade succeeded in effecting a breach.

As soon as this was done the impatient infantry were ordered to the assault, and rushing in, overpowered all resistance, and slew all within the enclosure, save a few who effected their escape by leaping from the wall at the rear.

It was now late in the afternoon, and operations ceased for the day.  The buildings on which the enemy had chiefly relied for their defence had been captured, and the difficulties still to be encountered were comparatively small.  The next day an attack was made upon a strong building known as the Mess House.  This was first breached by the artillery, and then carried by assault by the 53rd and 90th regiments, and a detachment of Sikhs; the latter, single handed, storming another building called the Observatory, in the rear of the Mess House.

At the same time the garrison of the Residency had, in accordance with the plan brought out by Kavanagh, begun operations on their side.  The capture of the Secunderbagh and Mosque had been signalled to them, and while the attack on the Mess House was being carried out they had blown down the outer wall of their defences, shelled the ground beyond, and then advanced, carrying two large buildings facing them at the point of the bayonet.

All day the fighting continued, the British gaining ground on either side.  The next day the houses still intervening between them were captured, and in the afternoon the defenders of the Residency and the relieving force joined hands.  The total loss of the latter was 122 officers and men killed and 345 wounded.

Frank Mallett’s letter to Sir John Greendale was not sent off.  He received a bullet through the left arm as the troops advanced against the Secunderbagh, but, using his sash as a sling, led on his company against the defenders crowded in the garden, and took part in the desperate fighting.  Three of his brother officers were killed during the three days’ fighting, and five others wounded.
