Lal Singh was, a shopkeeper native to Sahgol in the Jehlum District. He entered the service of the Sikh government in 1832, working as a writer in the treasury, and, according to some sources, converting from his original Hinduism to Sikhism in order to secure a place at court. He was patronised by the Wazirs Dhian Singh Dogra and Hira Singh Dogra, gaining favour by engineering, in 1843, the murders of Beli Ram and Bhai Gurmukh Singh, both of whom were disliked by Hira Singh. Hira gave Lal military commands, granted him the title of Rajah and numerous jagirs at Rohtas, and appointed him tutor to Maharajah Duleep Singh in the place of Duleep's uncle, Jawahar Singh. Nevertheless, when Maharani Jind Kaur turned against Hira Singh, Lal supported the Maharani and her brother Jawahar, helping them to persecute Hira Singh. Lal quickly won the Maharani's confidence, and became her closest advisor - contemporaries assumed that he was her lover, but Lal himself denied this in later life - being appointed to the Council of Regency. In February 1845, he was sent to Jammu at the head of an army to negotiate with Gulab Singh. When Jawahar Singh, who had since been appointed Wazir, was assassinated by the Sikh Khalsa Army on 21 September 1845, Lal Singh was made Wazir of the Sikh Empire in his place on 8 November.
During the First Anglo-Sikh War of 1845-1846, Lal Singh took personal command of the Khalsa, but alongside Tej Singh, he was secretly working with the British, sending information to and receiving orders from Captain Peter Nicholson, an officer stationed at Ferozepur. According to Alexander Gardner, who was in Lahore at this time, the Maharani, Lal, and Tej wanted to use the war as an opportunity to neutralise the growing threat of the Khalsa, who were becoming rebellious. At the start of the war, Lal kept his divisions entrenched at Ferozeshah even when the British garrison at Ferozepur was open to attack, allowing John Hunter Littler to retreat from the village and join forces with Hugh Gough. Gough's East India Company army subsequently defeated the Khalsa in the Battle of Mudki, from which Lal fled after a single exchange of fire, and at the Battle of Ferozeshah, which was only won with the help of Tej Singh's treachery. Lal himself supposedly sheltered in a ditch during the battle. With his own treachery suspected by the men under his command, Lal Singh once again fled with his irregular cavalry, making his way to Lahore, where he offered before the Khalsa to relinquish his office. Although he was relieved of the office of Wazir, replaced by Gulab Singh on 31 January 1846, he retained military command, and was present at the Battle of Sobraon on 10 February. Before the battle, Lal Singh allegedly betrayed the Khalsa once again, sending a map of the Sikh entrenchments to Nicholson. During the battle itself, Lal kept his artillery and cavalry off the field, and once again retired to Lahore.
Aftermath and exile
In the aftermath of the First Anglo-Sikh War, Lal Singh was rewarded by the British by being confirmed as Wazir of the State of Lahore under Henry Lawrence. However, he fell from grace when it was discovered that he had sent written instructions to the Governor of Kashmir to thwart Gulab Singh's attempts to occupy the Vale of Kashmir, which had been granted him by the British under the Treaty of Amritsar. Lal was tried by a Court of Inquiry, found guilty, and exiled to Agra with a pension of 12,000 rupees a year. He was interviewed by journalist John Lang, who found that he had no complaints about his situation, and had taken up archaeology and surgery as hobbies. He was later moved to Dera Doon, where he eventually died in 1866.
