How did the Cabinet Mission bring Baldev Singh into government?
A businessman-turned-politician who opposed Partition without Sikh safeguards ended up joining the very Interim Government that oversaw the transfer of power.
Sardar Baldev Singh was born in 1902 in Dumna, a village in Punjab’s Rupar district. He studied at Khalsa College, Amritsar, a key institution of Sikh higher learning.
Before politics, he ran his father’s steel and engineering business in Jamshedpur.
Britain’s 1946 Cabinet Mission arrived to negotiate the transfer of power to Indian leaders. Baldev Singh opposed Partition and demanded firm safeguards for the Sikh minority instead.
He joined the Interim Government on 2 September 1946 as the Sikhs’ sole nominee.

Baldev Singh joined the Interim Government on 2 September 1946 as the Sikh community’s sole nominee, following the Cabinet Mission’s arrival. True or false?
True. He had opposed Partition and demanded firm safeguards for the Sikh minority instead, before this appointment.
How did Baldev Singh fight for Sikh interests during Partition?
India’s first Defence Minister was also a first-hand advocate for Sikh territorial and community interests, right up to the eve of the boundary award.
On 15 August 1947, Baldev Singh became independent India’s first Minister of Defence. He was also the first Sikh to hold a Defence Ministry post in any country.
In a letter to Viceroy Mountbatten dated 1 May 1947, he demanded Lahore, Amritsar, and Gurdaspur go to India.
He argued these districts held large Sikh populations and assets vital to Sikh survival after Partition. He warned the final Radcliffe award would provoke strong anger among Sikhs in Punjab.
With Home Minister Sardar Vallabhbhai Patel, he organised military escorts for refugees fleeing West Punjab.

Baldev Singh was the first Sikh to hold a Defence Ministry post in any country. True or false?
True. He also wrote to Viceroy Mountbatten on 1 May 1947 demanding Lahore, Amritsar, and Gurdaspur go to India, warning the final Radcliffe award would provoke strong anger among Sikhs.
How did a brand-new Defence Minister respond to the Kashmir invasion?
Barely two months into the job, Baldev Singh helped organise the emergency response that saved Srinagar from a tribal invasion.
In October 1947, Pakistani tribal raiders invaded Kashmir, barely two months into his tenure.
Nehru, Patel, and Baldev Singh formed an emergency Defence Committee to respond to the invasion.
The committee ordered troops into the Valley after Maharaja Hari Singh signed the Instrument of Accession.
Baldev Singh backed the rapid airlift of soldiers under Lt. Gen. Cariappa to defend Srinagar.
Indian forces held the Valley and secured key territory through the conflict that followed.

India’s troops entered Kashmir before Maharaja Hari Singh had signed the Instrument of Accession. True or false?
False. The Defence Committee ordered troops into the Valley only after the Instrument of Accession was signed, backing a rapid airlift under Lt. Gen. Cariappa to defend Srinagar.
How did Baldev Singh handle Hyderabad and Junagadh?
Beyond Kashmir, Baldev Singh’s ministry managed two more princely-state crises, working closely with Patel on both.
He also managed the Defence Ministry’s role when Junagadh‘s ruler tried to accede to Pakistan.
In September 1948, Baldev Singh and his commanders finalised plans for Operation Polo against Hyderabad.
The operation ended Hyderabad’s resistance and brought the state into the Indian Union.
Throughout, he worked closely with Patel, the minister leading princely state integration.

Operation Polo, finalised in September 1948, ended Hyderabad’s resistance and brought the state into the Indian Union. True or false?
True. Baldev Singh’s Defence Ministry also separately managed Junagadh’s attempted accession to Pakistan, working closely with Patel on both crises.
How did Baldev Singh reshape India’s military command?
Baldev Singh’s most lasting institutional legacy was ending a colonial-era arrangement that had left India’s top military post outside civilian control.
Under British rule, India’s Commander-in-Chief held sweeping, largely independent authority.
Baldev Singh oversaw the shift that placed the Commander-in-Chief under civilian ministerial control.
This change built the institutional base for civilian oversight of India’s armed forces.
He served as Defence Minister until 13 May 1952, then held a Cabinet berth for Natural Resources.
Sardar Baldev Singh died on 29 June 1961, remembered as India’s founding Defence Minister.

Exam Angle: The Cabinet Mission That Brought Baldev Singh to Power
A UPSC Prelims question asked which statements about the Cabinet Mission are correct; the answer was “1 only.”
That same Cabinet Mission process led directly to Baldev Singh’s entry into the Interim Government in September 1946.
Examiners often link a person’s cabinet entry date to the constitutional event that created the seat.
Students commonly confuse “first Defence Minister of India” with “first Defence Member” of the pre-independence Interim Government — Baldev Singh held both titles, at different dates.
Expect questions connecting him to the Radcliffe Line, Operation Polo, or the 1947 Kashmir Defence Committee.
