Brigadier-General Neill having been killed on the 25th of September 1857, Colonel Stisted was appointed brigadier of the 1st brigade, and Major Haliburton assumed command of the regiment.

After the heavy loss sustained by the relieving force in pushing its way through the enemy, it was clearly impossible to carry off the sick, wounded, women, and children (amounting to not fewer than 1500) through five miles of disputed suburb; the want of carriage alone rendering it an impossibility. It was therefore necessary for the now considerably increased garrison to maintain itself in its present position on reduced rations until reinforcements should advance to its relief. Brigadier Inglis retained command of the old Lucknow garrison, reinforced by the volunteer cavalry, Madras Fusiliers, and a detachment of the 78th; while General Havelock commanded the field force that occupied the palaces and outposts.

One of the enemy’s batteries, known as Phillip’s Battery, still remained in a strong position close to the Residency, and continued to annoy the garrison by its fire; its capture, therefore, became necessary, and a force, consisting in all of 568 men, of which the 78th formed a part, was placed at the disposal of Colonel Napier, of the Bengal Engineers, on the 1st of October. On the afternoon of that day the column formed on the road leading to the Pyne Bagh, and advancing to some houses near the Jail, drove the enemy away from them and from a barricade, under a sharp musketry fire. The column having to work its way through strongly barricaded houses, it was late before a point was reached from which the enemy’s position could be commanded. This having been obtained, and it being found, on reconnoitring, that the battery was in a high position, scarped, and quite inaccessible without ladders, it was determined to defer the assault till daylight. The position gained having been duly secured and loopholed, the men occupied the buildings for the night, and were subjected to a heavy fire from the battery.

On the morning of the 2nd the troops advanced, covered by a fire of artillery from the Residency entrenchment. A severe fire was opened from a barricade which flanked the battery on the right; but this being turned, the troops advanced and drove the enemy from the battery, capturing the guns, which had been withdrawn to some distance, and driving off the enemy, who defended them with musketry and grape. The guns having been destroyed, and Phillip’s house blown up, the troops withdrew to their position of the previous night, the 78th having lost 1 man killed and 3 wounded.

The command of this sallying party now fell to Major Haliburton of the 78th, who, under instructions from the general, commenced on the 3rd of October to work from house to house with crowbar and pickaxe, with a view to the possibility of adapting the Cawnpoor road as the line of communication with the Alum Bagh. On the 4th, Major Haliburton was mortally wounded and his successor disabled. On the 6th the proceedings were relinquished, and the troops gradually withdrew to the post at the junction of the Cawnpoor road and Main Street, which was occupied by the 78th Highlanders, and retained by that regiment as a permanent outpost during the two months’ blockade which ensued.

The regiment being greatly reduced, both in officers and men, the ten companies were told off into four divisions, each under the command of an officer—Captain Hay, Lieutenants Cassidy, Finlay, and Barker. The position was divided into three different posts, each defended by one of these divisions, the fourth being in reserve. By this arrangement, each man was on guard for three days and nights out of four, and on the fourth day was generally employed on a working party in erecting the defences.

Everything was now done by the garrison to strengthen its position; barricades were erected at all available points, the defences of the Residency were improved, and all the palaces and buildings occupied by the field force were put into a state of defence. One of the greatest dangers that the besieged had to apprehend was from the enemy’s mines, which threatened the position of the British from every possible quarter, thus requiring the garrison to be continually on the alert, and to be constantly employed in countermining. In this the garrison was very successful, the underground attempts of the besiegers being outwitted on almost every hand, and many of their mines frequently destroyed. The outpost of the 78th, under Captain Lockhart (who on the death of Major Haliburton took command of the regiment, and held it during the rest of the siege), was vigorously assailed by these means by the enemy; but they were completely outwitted by some of the soldiers of the 78th (who volunteered for this work, for which they received extra pay at the rate of 10s. per diem), directed by Lieutenant Hutchinson, of the Bengal Engineers, and Lieutenant Tulloch, Acting Engineer.

The enemy kept so persistently sinking shafts and driving galleries towards the position occupied by the 78th, that in order to countermine them five shafts were sunk at several angles of the position, from each of which numerous galleries were driven, of a total length of 600 feet. Indeed, in regard to the mining operations in connection with the siege of Lucknow, Sir James Outram wrote, “I am aware of no parallel to our series of mines in modern war; 21 shafts, aggregating 200 feet in depth, and 3291 feet of gallery, have been erected. The enemy advanced 20 mines against the palace and outposts.”

The post of the 78th was all this time exposed by day and night to a ceaseless fire of shot, shell, and musketry, and scarcely a day passed in which some casualty did not occur. The outer walls of the houses forming the post were reduced to ruins by round shot, and sharp-shooters occupied the houses around to within 50 yards, watching for their prey. All the other regiments were similarly situated during the two months’ blockade.

The rations had now for some time been reduced to one-half, and the troops, having left everything behind them at the Alum Bagh, had nothing to wear but the clothes they wore on entering. At length, however, tidings of relief arrived.
