Second World War

In 1941, Rajendrasinhji was sent to the Mediterranean and Middle East Theatre as a squadron commander of the 2nd Lancers. In April 1941, his brigade, the 3rd Indian Motor Brigade, was surrounded at Mechili by numerically superior Axis forces. Being encircled, the allied forces were left with no option but to hazard a headlong foray through the enemy forces, into the desert. Rajendrasinhji's squadron took the rearguard position during this operation. While the vanguard suffered much loss of life by a German tank attack, Rajendrasinhji's squadron was not seriously impacted. He led his squadron in a charge through the enemy ranks, and they gained respite in the safety of some nearby hills. The squadron essayed further action on the enemy forces after nightfall and achieved considerable success; indeed, it returned to base with sixty prisoners of war.^[7][8]

For his courageous leadership and determined action, Rajendrasinhji was awarded the Distinguished Service Order (DSO) in 1941.^[9] He was the first Indian to be honoured with this decoration during the Second World War.

Returning to India in October 1942, Rajendrasinhji was appointed commandant of 2 Royal Lancers in 1943.^[10] In May 1945, he was appointed the army's Deputy Director of Public Relations and posted to Washington, with a further appointment as military attache there from June.^[10] He was promoted to brigadier in September 1946 and assigned to command the Piska sub-area. He was then appointed the first Indian director of the Indian Armoured Corps, and shortly before Independence was promoted acting Major General on 30 July 1947.^[10]

In India

The Partition of India in 1947 caused an upheaval in both the security situation and the dynamics of the Indian army. The partition meant the division of the Indian army, which was concurrently called upon to deal with several critical security situations arising from the partition of the country and the anticipated integration of the princely states. Also during this period, British officers who held most of the senior ranks in the Indian army were gradually disengaged, being replaced with Indian officers. During this critical period, Rajendrasinhji was called upon to shoulder many onerous responsibilities and received rapid promotion in rank commensurately. As a new major-general, he was appointed to command the Delhi sub-area after Independence in August 1947, serving until 1948 as General Officer Commanding (GOC) of the redesignated Delhi and East Punjab Command (1947–48).^[10] He was promoted acting Lieutenant General on 16 January 1948 and appointed GOC-in-C Eastern Command.^[11] He was then appointed GOC-in-C Southern Command (1948–53), following the retirement of Lt. General E. N. Goddard. Operation Polo, which resulted in the integration of Hyderabad State with India, was executed during his term in office as GOC-in-C (South).^[12]

As the senior-most serving officer in the army, Gen. Rajendrasinhji was appointed Commander-in-Chief, Indian Army on 14 January 1953, following the retirement of General (later Field Marshal) K. M. Cariappa. Rajendrasinhji received the rank of General on the same day. With effect from 1 April 1955, the President of India was constitutionally designated the Commander-in-chief of the Indian Armed Forces. Rajendrasinhji then became the first head of the Indian army to be designated Chief of Army Staff. He held that office until his retirement from service on 14 May 1955 and was succeeded by Gen. S.M. Srinagesh.^[13]
