Solution:

• HMIS Talwar was a shore establishment of the British Royal Indian Navy during World War II, located in Colaba, Bombay.
• On 18 February 1946, the ratings of Talwar, declared a hartal (“strike”), and refused duty. The next day the “mutiny” spread to the RIN Depot at Castle Barracks, and to ships in Bombay harbour.
• Demonstrations became violent and several arrests were made. Flag Officer, Bombay, received delegates from the mutineers and was presented with a list of demands, including improvements in pay rates and conditions, faster demobilisation according to age and service, and disciplinary action against the commanding officer of Talwar for alleged poor treatment of ratings
