The regiment was joined at Cawnpoor by Colonel Stisted, Captain Archer, and No. 4 Company.

Early on the morning of the 16th of August the movable column marched against Bithoor, the residence of Nana Sahib, about 14 miles from Cawnpoor. About noon the column came in sight of the enemy, numbering in all, infantry and cavalry, about 4000, strongly posted. General Havelock called it “one of the strongest positions in India.” The plain in front of the enemy’s position was covered with thick sugar-cane plantations, which reached high above the heads of the men, and their batteries were defended by thick ramparts flanked by entrenched quadrangles. The whole position was again flanked by other villages and comprehended the town of Bithoor.

The enemy having opened upon the advancing British force a continued shower of shot and shell, and as the British guns made no impression upon them, it was resolved to have recourse to the bayonet, and a simultaneous advance of the line was ordered. While the Fusiliers moved upon the flanking villages, the 78th advanced upon the batteries, alternately lying down and moving on, as the volleys of grape issued from the enemy’s guns. The rebels awaited the approach of the advancing men until the foremost entered the works, when they fled in confusion. The British troops pursued the enemy into and through the town, but being completely knocked up by exposure to the fierce sun, and by the great fatigue they had undergone, could follow the retreating rebels no further, and bivouacked on the ground they had won.

The 78th had in this affair only Captain Mackenzie and 10 men wounded, though several men died of cholera, which had again broken out.

The next morning the force returned to Cawnpoor, and took up a position on the plain of Subada, where General Havelock issued a commendatory and stirring note, in which he told the small force that it “would be acknowledged to have been the prop and stay of British India in the time of her severest trial.”

During the next month the force rested at Cawnpoor, while reinforcements gradually arrived. Immediately on crossing the Ganges cholera broke out, and carried off a great number of the little band. The headquarters of the 78th lost from this cause alone 1 officer, Captain Campbell, and 43 men. The strength of the regiment was still further reduced by the departure of 1 officer and 56 men, sick and wounded, to Allahabad. At the end of the month, however, the five companies that had been left behind, and the detachment that came from Chinsurah by the steamer route, joined headquarters from Allahabad.

In the middle of September the regiment was supplied with Enfield rifles, but there was little time left for giving the men any instruction in the use of that weapon.

The force despatched from England to assist in the Chinese war (the 23rd, 82nd, 90th, and 93rd Regiments) had been stopped at Singapore and brought to Calcutta. The 37th Regiment also arrived from Ceylon, and the 5th from Mauritius. Of these regiments, the 5th and 90th were immediately on arrival sent up the country, and reached Cawnpoor in the beginning of September. Sir James Outram also arrived at this time, having been appointed to the military command of the Cawnpoor and Dinapoor divisions.

A bridge of boats was thrown across the Ganges, and every preparation made for another attempt to relieve Lucknow, the garrison of which was still successfully and heroically holding out. On the 16th of September, Sir James Outram issued a division order, in which he generously resigned to Major-General Havelock the honour of leading on the force intended to make a second attempt to relieve Lucknow. This Sir James did “in gratitude for, and in admiration of the brilliant deeds in arms achieved by General Havelock and his gallant troops.” Sir James was to accompany the force as a volunteer, and on the relief of Lucknow would resume his position at the head of the forces.

The army of relief was divided into two brigades of infantry and one of artillery, as follows:—First brigade of infantry, under Brigadier-General Neill, consisted of the 5th Fusiliers, 84th Regiment, 1st Madras Fusiliers, and 100 men of the 64th Regiment. Second brigade of infantry, under Colonel Walter Hamilton of the 78th, consisted of the 78th Highlanders under Colonel Stisted, 90th light infantry, and the Sikh regiment of Ferozepoor. The Artillery brigade, under Major Cooper, B.A., consisted of the batteries of Captain Maude, Captain Olphert, and Brevet-Major Eyre. The volunteer cavalry, a few irregulars, under Captain Barrow, and a small body of Engineers, accompanied the forces. The entire force was under the command of Brigadier-General Havelock, accompanied, as we have stated, by Major-General Outram as a volunteer.
