The siege of Lucknow was the prolonged defence of the British Residency within the city of Lucknow from rebel sepoys (Indian soldiers in the British East India Company's Army) during the Indian Rebellion of 1857. After two successive relief attempts had reached the city, the defenders and civilians were evacuated from the Residency, which was then abandoned.
The state of Oudh/Awadh had been annexed by the British East India Company and the Nawab Wajid Ali Shah was exiled to Calcutta the year before the rebellion broke out. This high-handed action by the East India Company was greatly resented within the state and elsewhere in India. The first British Commissioner (in effect the governor) appointed to the newly acquired territory was Coverley Jackson. He behaved tactlessly, and Sir Henry Lawrence, a very experienced administrator, took up the appointment only six weeks before the rebellion broke out.
The sepoys of the East India Company's Bengal Presidency Army had become increasingly troubled over the preceding years, feeling that their religion and customs were under threat from the evangelising activities of the company. Lawrence was well aware of the rebellious mood of the Indian troops under his command (which included several units of Oudh Irregulars, recruited from the former army of the state of Oudh). On 18 April, he warned the Governor General, Lord Canning, of some of the manifestations of discontent, and asked permission to transfer certain rebellious corps to another province.
The flashpoint of the rebellion was the introduction of the Enfield rifle; the cartridges for this weapon were believed to be greased with a mixture of beef and pork fat, which was felt would defile both Hindu and Muslim Indian soldiers. On 1 May, the 7th Oudh Irregular Infantry refused to bite the cartridge, and on 3 May they were disarmed by other regiments.
On 10 May, the Indian soldiers at Meerut broke into open rebellion, and marched on Delhi. When news of this reached Lucknow, Lawrence recognised the gravity of the crisis and summoned from their homes two sets of pensioners, one of sepoys and one of artillerymen, to whose loyalty, and to that of the Sikh and some Hindu sepoys, the successful defence of the Residency was largely due.
On 23 May, Lawrence began fortifying the Residency and laying in supplies for a siege; large numbers of British civilians made their way there from outlying districts. On 30 May (the Muslim festival of Eid ul-Fitr), most of the Oudh and Bengal troops at Lucknow broke into open rebellion. In addition to his locally recruited pensioners, Lawrence also had the bulk of the British 32nd Regiment of Foot available, and they were able to drive the rebels away from the city.
On 4 June, there was a rebellion at Sitapur, a large and important station 51 miles (82 km) from Lucknow. This was followed by another at Faizabad, one of the most important cities in the province, and outbreaks at Daryabad, Sultanpur and Salon. Thus, in the course of ten days, British authority in Oudh practically evaporated.
On 30 June, Lawrence learned that the rebels were gathering north of Lucknow and ordered a reconnaissance in force, despite the available intelligence being of poor quality. Although he had comparatively little military experience, Lawrence led the expedition himself. The expedition was not very well organised. The troops were forced to march without food or adequate water during the hottest part of the day at the height of summer, and at the Battle of Chinhat they met a well-organised rebel force, led by Barkat Ahmad with cavalry and dug-in artillery. Whilst they were under attack, some of Lawrence's sepoys and Indian artillerymen defected to the rebels, overturning their guns and cutting the traces. His exhausted British soldiers retreated in disorder. Some died of heatstroke within sight of the Residency.
Lieutenant William George Cubitt, 13th Native Infantry, was awarded the Victoria Cross several years later, for his act of saving the lives of three men of the 32nd Regiment of Foot during the retreat. His was not a unique action; sepoys loyal to the British, especially those of the 13th Native Infantry, saved many British soldiers, even at the cost of abandoning their own wounded men, who were hacked to pieces by rebel sepoys.
As a result of the defeat, the detached turreted building, Machchhi Bhawan (Muchee Bowan), which contained 200 barrels (~27 t) of gunpowder and a large supply of ball cartridge, was blown up and the detachment withdrew to the Residency.
Lawrence retreated into the Residency, where the siege now began, with the Residency as the centre of the defences. The actual defended line was based on six detached smaller buildings and four entrenched batteries. The position covered some 60 acres (240,000 m2) of ground, and the garrison (855 British officers and soldiers, 712 Indians, 153 civilian volunteers, with 1,280 non-combatants, including hundreds of women and children) was too small to defend it effectively against a properly prepared and supported attack. Also, the Residency lay in the midst of several palaces, mosques and administrative buildings, as Lucknow had been the royal capital of Oudh for many years. Lawrence initially refused permission for these to be demolished, urging his engineers to "spare the holy places". During the siege, they provided good vantage points and cover for rebel sharpshooters and artillery.
One of the first bombardments following the beginning of the siege, on 30 June, caused a civilian to be trapped by a falling roof. Corporal William Oxenham of the 32nd Foot saved him while under intense musket and cannon fire, and was later awarded the Victoria Cross. The first attack was repulsed on 1 July. The next day, Lawrence was fatally wounded by a shell, dying on 4 July. Colonel John Inglis of the 32nd Regiment took military command of the garrison. Major John Banks was appointed the acting Civil Commissioner by Lawrence. When Banks was killed by a sniper a short time later, Inglis assumed overall command.
About 8,000 sepoys who had joined the rebellion and several hundred retainers of local landowners surrounded the Residency. They had some modern guns and also some older pieces which fired all sorts of improvised missiles. There were several determined attempts to storm the defences during the first weeks of the siege, but the rebels lacked a unified command able to coordinate all the besieging forces.
The defenders, their number constantly reduced by military action as well as disease, were able to repulse all attempts to overwhelm them. On 5 August a rebel mine was foiled; counter mining and offensive mining against two buildings brought successful results. Several sorties were mounted, attempting to reduce the effectiveness of the most dangerous rebel positions and to silence some of their guns. The Victoria Cross was awarded to several participants in these sorties: Captain Samuel Hill Lawrence and Private William Dowling of the 32nd Foot and Captain Robert Hope Moncrieff Aitken of the 13th Native Infantry.
On 16 July, a force under Major General Henry Havelock recaptured Cawnpore, 48 miles (77 km) from Lucknow. On 20 July, he decided to attempt to relieve Lucknow, but it took six days to ferry his force of 1500 men across the Ganges River. On 29 July, Havelock won a battle at Unnao, but casualties, disease and heatstroke reduced his force to 850 effectives, and he fell back.
Havelock managed to get a spy through to the Residency, telling them that two rockets would be fired at a certain time on the night when the relief force was ready to attack.
There followed a sharp exchange of letters between Havelock and the insolent Brigadier James Neill who was left in charge at Cawnpore. Havelock eventually received 257 reinforcements and some more guns, and tried again to advance. He won another victory near Unao on 4 August, but was once again too weak to continue the advance, and retired.
Havelock intended to remain on the north bank of the Ganges, inside Oudh, and thereby prevent the large force of rebels which had been facing him from joining the siege of the Residency, but on 11 August, Neill reported that Cawnpore was threatened. To allow himself to retreat without being attacked from behind, Havelock marched again to Unao and won a third victory there. He then fell back across the Ganges, and destroyed the newly completed bridge. On 16 August, he defeated a rebel force at Bithur, disposing of the threat to Cawnpore.
