How the 1946 Royal Indian Navy mutiny hastened India's independence
More than 80 years ago, India was ruled by Britain, and many Indian people wanted freedom.
Britain had a navy in India called the Royal Indian Navy, while Britain's own Royal Navy handled the biggest ocean missions.
During World War II, the Royal Indian Navy grew from fewer than 2,000 sailors to almost 30,000.
When the war ended, Britain wanted to send most of those sailors home, and some British officers treated the sailors rudely.
On February 18, 1946, more than a thousand sailors in Bombay went on strike to protest.
Their protest spread quickly to ships and naval bases all over India, and about 20,000 sailors joined in.
Many ordinary people in Bombay also joined, and shops and transport stopped.
The British fired at the crowds, and at least 400 people were killed.
The British realised they could no longer control India with their own forces.
Many historians believe this big protest made Britain leave India sooner, and it is sometimes called the "last war of independence".
On February 18, 1946, more than a thousand Royal Indian Navy (RIN) ratings in Bombay went on strike, and the revolt spread to naval units across British India.
Anger was fueled by post-war demobilisation from about 30,000 to 11,000 personnel, racist abuse by Commander Arthur Frederick King, poor food and conditions, and the Indian National Army (INA) trials.
Sailors demanded King's discipline, better service conditions, British withdrawal from Indonesia and free trials for INA detainees; they called themselves the Indian National Navy and Azad Hindis, after the Azad Hind Fauj (INA).
About 78 ships, 20 shore establishments, nearly 100 naval units and almost 20,000 personnel joined; civilians including nearly three lakh Bombay mill workers rallied, and police firing on February 22 killed at least 400 people.
Historian Commodore Srikant Kesnur calls the mutiny the "last war of independence" that rattled the British and hastened India's independence.

- The mutiny began on February 18, 1946; police firing on protesters took place on February 22, 1946.

Historians who credit the mutiny
Skeptics who downplay its impact
Did the mutiny hasten India's independence?
Historians who credit the mutiny
Historians such as Commodore Srikant Kesnur call the RIN mutiny the 'last war of independence' that rattled the British and hastened independence; Justice Chakravartti recorded that former UK Prime Minister Clement Attlee said the INA trials and the RIN mutiny made the British leave India.
Skeptics who downplay its impact
The rebel sailors eventually surrendered, so the insurrection failed; the recorded remark attributed to Attlee is a contention 'people may debate', and the mutiny lacked a charismatic leader like Netaji (Subhas Chandra Bose), so it did not get widespread traction.
How should the mutiny be remembered?
Historians who credit the mutiny
It deserves recognition because it showed the British that core state forces such as the Royal Indian Air Force, the Indian Army and the Navy were no longer cooperating in putting down the strike, meaning they could no longer rule.
Skeptics who downplay its impact
A newly born independent Navy was uncomfortable with the idea of a mutiny — and correctly so — which is one reason the event did not get the attention it might have received.
Which political parties backed the mutiny?
Historians who credit the mutiny
The Communists backed the 1946 mutiny.
Skeptics who downplay its impact
The Indian National Congress and the Muslim League did not back the mutiny.
