Let's break down the question about the first Indian Commander-in-Chief of the Indian Army and look at the options provided.

Understanding the Role: Commander-in-Chief of the Indian Army

The Commander-in-Chief (C-in-C) was the head of the Indian Army. Before India gained independence and became a republic, this post was held by British officers. The transition to an Indian holding this prestigious position marked a significant moment in the history of the Indian armed forces.

Identifying the First Indian Commander-in-Chief

We are looking for the first Indian officer who took command of the Indian Army after the British handed over the reins. Let's examine the options:

• General Sam Manekshaw: He is a legendary figure, known for leading the Indian Army to victory in the 1971 war. However, he became Chief of the Army Staff much later than the first Indian C-in-C.
• General Arjan Singh: He was a distinguished officer, but he served in the Indian Air Force, eventually becoming Marshal of the Indian Air Force. The question is about the Indian Army.
• General K. M. Cariappa: Kodandera Madappa Cariappa was an officer who rose through the ranks before independence. He played a crucial role in the transition of the Indian Army.
• General Maharaj Rajendra Sinhji: He was also a senior officer in the Indian Army and succeeded General K. M. Cariappa as the Commander-in-Chief.

Based on historical records, General K. M. Cariappa was the first Indian to be appointed as the Commander-in-Chief of the Indian Army. He took charge on January 15, 1949. This date is celebrated annually as Army Day in India to honour the soldiers of the nation.

Therefore, General K. M. Cariappa holds the distinction of being the first Indian Commander-in-Chief of the Indian Army.

Additional Information: Indian Army Day and C-in-C History

The day General K. M. Cariappa took over as the first Indian Commander-in-Chief, January 15th, is celebrated as "Army Day" every year. Before 1955, the head of the Army was known as the "Commander-in-Chief." After 1955, the designation was changed to "Chief of the Army Staff" (COAS). General Maharaj Rajendra Sinhji was the last Commander-in-Chief and the first Chief of Army Staff.

General K. M. Cariappa replaced General Sir Francis Butcher, the last British Commander-in-Chief of India. This transition symbolized the complete Indianisation of the Indian Army's leadership.
