Singh graduated from Sandhurst as a King's Commissioned Indian Officer in 1931. He was commissioned as a second lieutenant on 29 January and placed in the unattached list of the Indian Army. Newly commissioned Indian officers were attached with a British unit before being sent to an Indian unit. He was attached with the 2nd Battalion, York and Lancaster Regiment. After an year's attachment, he was posted to 3 Cavalry.

After completing the course, he returned to India and was appointed General officer commanding (GOC) East Punjab Area in the acting rank of major general. He subsequently commanded an infantry division in the Bengal Area. He later became GOC Bombay Area. On 29 January 1956, Singh was made substantive major general.[6] He also commanded the 1st Armoured Division.[2]

On 22 November 1963, Singh was killed when his helicopter crashed en route to Poonch. In a great loss to the Indian Armed Forces, the crash claimed six distinguished officers.[12] The officers who were on the helicopter apart from Singh were:[11]
Major General N K D Nanavati, General Officer Commanding 25 Infantry Division
Brigadier S R Oberoi, Commander 93 Infantry Brigade
Flight Lieutenant S S Sodhi, Pilot
The news of the air crash came as a shock to the nation. A black-bordered extraordinary Gazette of India was issued on 23 November.[11] The issue was raised in both houses of Parliament of India and addressed by the Minister of DefenceYashwantrao Chavan. The Rajya Sabha observed one minute's silence as a mark of respect to the memory of the deceased and adjourned for the day.[13] The Ministry of Defence, the three service headquarters and all defence establishments in New Delhi were closed on 23 November as a mark of respect. All public events of the Defence Minister and Service Chiefs were also cancelled.[14] The officers were laid to rest with full military honours.[15] Singh was awarded the Param Vishisht Seva Medal posthumously on 26 January 1964.[16]
A memorial has been built at the site of the air crash, commemorating the names of the victims.[17] The Indian Army organises an annual event to pay homage to them. An 'Akhand Path' is also organised by the people of Poonch and surrounding villages, as a mark of their love and affection towards the departed souls, every year to commemorate the tragic accident.[18]
In April 1964, the Government of Himachal Pradesh constructed the General Daulet Singh Park in Shimla in recognition and to commemorate the distinguished service of Singh. A bust of Singh is also installed in the park. The park was inaugurated by Singh's successor as Western Army Commander – then Lieutenant General Sam Manekshaw.[19]
