The siege of Delhi was a decisive conflict of the Indian Rebellion of 1857. The rebellion against the authority of the East India Company was widespread through much of Northern India, but was essentially sparked by the mass uprising by the sepoys of the Bengal Army, which the company had itself raised in its Bengal Presidency (which actually covered a vast area from Assam to the borders of Delhi). Seeking a symbol around which to rally, the first sepoys to rebel sought to reinstate the power of the Mughal Empire, which had ruled much of the Indian subcontinent in the previous centuries. Lacking overall direction, many who subsequently rebelled also flocked to Delhi.
This made the siege decisive for two reasons. Firstly, large numbers of rebels were committed to the defence of a single fixed point, perhaps to the detriment of their prospects elsewhere, and their defeat at Delhi was thus a very major military setback. Secondly, the British recapture of Delhi and the refusal of the aged Mughal Emperor Bahadur Shah II to continue the struggle deprived the rebellion of much of its national character. Although the rebels still held large areas, there was little co-ordination between them, and the British were able to overcome them separately.
Outbreak of the rebellion
After several years of increasing tension among the sepoys (Indian soldiers) of the British East India Company's Bengal Army, the sepoys at Meerut, 43 miles (69 km) northeast of Delhi, openly rebelled against their British officers. The flashpoint was the introduction of the Pattern 1853 Enfield rifle. The cartridges for this were widely believed to be greased with a mixture of cow and pig fat, and to bite them open when loading the rifle (as required by the drill books) would defile both Hindu and Muslim soldiers.
Eighty-five men of the 3rd Bengal Cavalry stationed at Meerut refused to accept their cartridges. They were hastily court martialled, and on 9 May 1857 they were sentenced to long periods of imprisonment and were paraded in irons before the British and Bengal regiments in the garrison. On the evening of the following day, soldiers of the Bengal regiments (3rd Light Cavalry, 11th and 20th Infantry) rebelled, releasing the imprisoned troopers and killing their British officers and many British civilians in their cantonment.
The senior Company officers at Meerut were taken by surprise. Although they had ample warning of disaffection among the Bengal Army after earlier outbreaks of unrest at Berhampur, Barrackpur and Ambala, they had assumed that at Meerut, where the proportion of European to Indian troops was higher than anywhere else in India, the Bengal units would not risk open revolt. They were fortunate that they did not suffer disaster. The Bengal regiments broke into rebellion on Sunday, when European troops customarily attended evening church parade without arms. Due to the increasingly hot summer weather, the church services on 10 May took place half an hour later than on previous weeks, and when the outbreak occurred, the British troops had not yet left their barracks and could quickly be mustered and armed.
Other than defending their own barracks and armouries, the company's commanders at Meerut took little action, not even notifying nearby garrisons or stations. (The telegraph had been cut, but dispatch riders could easily have reached Delhi before the sepoys, had they been sent immediately.) When they had rallied the British troops in the cantonment and prepared to disperse the sepoys on 11 May, they found that Meerut was quiet and the sepoys had marched off to Delhi.
Capture of Delhi by the rebels
Delhi was the capital of the Mughal Empire, which had been reduced to insignificance over the preceding century. The emperor, Bahadur Shah II, who was 82, had been informed by the East India Company that the title would die with him. At the time, Delhi was not a major centre of Company administration, although Company officials controlled the city's finances and courts. They and their families lived in the "Civil Lines" to the north of the city.
There were no units of the British Army or "European" units of the East India Company forces at Delhi. Three Bengal Native Infantry regiments (the 38th, 54th and 74th) were stationed in barracks 2 miles (3.2 km) north-west of the city. They provided guards, working parties and other details to a "Main Guard" building just inside the walls near the Kashmiri Gate on the northern circuit of walls, the arsenal in the city and other buildings. By coincidence, when the regiments paraded early in the morning of 11 May, their officers read out to them the general order announcing the execution of sepoy Mangal Pandey, who had attempted to start a rebellion near Barrackpore earlier in the year, and the disbandment of his regiment, the 34th Bengal Native Infantry. This produced much muttering in the ranks.
Later in the morning, the rebels from Meerut arrived quite unexpectedly, crossing the bridge of boats over the Jumna River. The leading sowars (troopers) of the 3rd Light Cavalry halted under the windows of the Palace and called on the Emperor to lead them. Bahadur Shah called for them to go to another palace outside the city, where their case would be heard later. Company officials then tried to close all the city gates, but were too late to prevent the sowars gaining entry through the Rajghat Gate to the south. Once inside, the sowars were quickly joined by mobs which began attacking Company officials and looting bazaars.
Some Company officers and civilians tried to take refuge in the Main Guard, but the sepoys there joined the revolt, and they were slaughtered. Other officers arrived from the barracks, accompanied by two field guns and several companies of sepoys who had not yet joined the rebellion, and recaptured the Main Guard, sending the bodies of the dead officers to the cantonments in a cart. In the city meanwhile nine British officers from the Ordnance Corps, led by George Willoughby were conducting the Defence of the Magazine, which contained artillery, stocks of firearms and ammunition. They found that their troops and labourers were deserting, using ladders provided from the palace to climb over the walls. The officers opened fire on their own troops and the mobs to prevent the arsenal falling intact into the rebels' hands. After five hours, they had run out of ammunition and blew up their magazine, killing many rioters and onlookers, and badly damaging nearby buildings. Only three of them escaped and received the Victoria Cross: John Buckley, George Forrest and William Raynor.
Shortly after this, the troops at the Main Guard were ordered to withdraw. The sepoys there, who had hitherto remained aloof from the revolt, turned on their officers, a few of whom escaped after the sepoys left to join the looting.
About half the European civilians in Delhi and in the cantonments and Civil Lines were able to flee, first to the Flagstaff Tower on the ridge to the north-west of Delhi where telegraph operators were trying to warn other British stations of the uprising. After it became clear that no help could arrive from Meerut or elsewhere, and the cart carrying the bodies of the officers killed at the Main Guard in the morning arrived at the tower by mistake, most of the Europeans fled to Karnal, several miles west. Some were helped by villagers on the way, others fell prey to plunderers.
Mughal restoration
On 12 May, Bahadur Shah held his first formal audience in several years. It was attended by several excited sepoys who treated him familiarly or even disrespectfully. Although Bahadur Shah was dismayed by the looting and disorder, he gave his public support to the rebellion. On 16 May, sepoys and palace servants killed 52 British who had been held prisoner within the palace or who had been discovered hiding in the city. The killings took place under a peepul tree in front of the palace, despite Bahadur Shah's protests. The avowed aim of the killers was to implicate Bahadur Shah in the killings, making it impossible for him to seek any compromise with the company.
The administration of the city and its new occupying army was chaotic, although it continued to function haphazardly. The Emperor nominated his eldest surviving son, Mirza Mughal, to be commander-in-chief of his forces, but Mirza Mughal had little military experience and was treated with little respect by the sepoys. Nor did the sepoys agree on any overall commander, with each regiment refusing to accept orders from any but their own officers. Although Mirza Mughal made efforts to put the civil administration in order, his writ extended no further than the city. Outside, Gujjar herders began levying their own tolls on traffic, and it became increasingly difficult to feed the city.
News of the rebellion at Meerut and the capture of Delhi spread rapidly throughout India. Rumours and envoys from the rebels spread the tidings fast and precipitated widespread rebellions and uprisings, but the Company learned of the events at Delhi even more quickly, thanks to the telegraph. Where the commanders of stations were energetic and distrustful of their sepoys, they were able to forestall some of the most dangerous revolts.
Company moves
Although there were several Company units available in the cool "hill stations" in the foothills of the Himalayas, it took time before any action could be taken to recapture Delhi. This was partly due to lack of transport and supplies. After the end of the Second Anglo-Sikh War, the Bengal Army's transport units had been disbanded as an economy measure, and transport had to be improvised from scratch. Also, many of the senior British officers were widely regarded as dotards, far too senile to act decisively or sensibly.
Nevertheless, a Company force under General George Anson, the commander-in-chief in India, was able to move from Ambala to Karnal starting on 17 May. On 7 June, they were joined at Alipur by a force from Meerut, which had fought several skirmishes en route. The Meerut force was led by Brigadier Archdale Wilson, who had conspicuously failed to prevent the rebel sepoys' move to Delhi on 11 May. Anson died of cholera at Karnal on 27 May. Under his successor, Major General Henry Barnard, the combined force advanced on Delhi.
On 8 June, they found the mutineers had entrenched themselves outside the city. They drove the large but disorganised rebel force from the field at the Battle of Badli-ki-Serai 6 miles (9.7 km) west of Delhi, and captured Delhi ridge 2 miles (3.2 km) north of the city and the Bengal infantry barracks to the west of it. As a gesture of defiance and contempt, they set fire to the barracks. This was a senseless act, as it condemned the besiegers (and all their sick and wounded and noncombatants) to live in tents through the hot weather and monsoon rain seasons.
The ridge was of hard rock, about 60 feet (18 m) high, and ran from a point only 1,200 yards (1,100 m) east of the Kabul Gate on the city walls to the Yamuna River 3 miles (4.8 km) north of the city. Fortunately for the besiegers, a canal ran from the Yamuna west of their encampments, protecting the rear of their camp and also providing drinking water. The besiegers occupied various fortified posts along the top of the ridge. The nearest to the city and the most exposed was known as "Hindu Rao's house", defended by the 60th Rifles and Gurkhas of the 8th (Sirmoor) Local Battalion. South of it was a maze of villages and walled gardens, called the Subzi Mundi, in which the rebel forces could gather before launching attacks on the British right.
The siege: June through July
It was quickly apparent that Delhi was too well-fortified and strongly held to fall to a coup de main. Barnard ordered a dawn assault on 13 June, but the orders were confused and failed to reach most of his subordinates in time. The attack had to be called off, amidst much recrimination. After this, it was accepted that the odds were too great for any assault to be successful until the besiegers were reinforced.
Large contingents of rebellious sepoys and volunteers continued to arrive in Delhi. The majority of no less than ten regiments of cavalry and fifteen of infantry of the Bengal Army rebelled and made their way to Delhi during June and July, along with large numbers of irregulars, mainly Muslim mujahaddin. As each new contingent arrived, the rebels made attacks on Hindu Rao's house and other outposts on several successive days. A major attack was mounted from three directions on 19 June, and nearly forced the exhausted besiegers to retreat, but the rebels did not know how close they came to success. Another major attack was made on 23 June, the centenary of the Battle of Plassey. (It was believed that the presence of East India Company in India would end one hundred years after this famous battle).So was the attack on the British Cavalry Lines on the night of 3 July beaten.
