The Bangladesh Navy was created as part of Bangladesh Forces during Bangladesh's 1971 liberation war against Pakistan. Its official creation date is July 1971 during the Bangladesh Sector Commanders Conference 1971. In 1971, with West Pakistan imposing a brutal military crackdown in East Pakistan, the Bangladesh Liberation War was already underway. Many Bengali sailors and officers in the Pakistan Navy defected to form the nascent Bangladesh Navy. Initially, there were two ships, "PADMA" and "PALASH", and 45 navy personnel. On 9 November 1971, the first naval fleet, consisting of six small patrol vessels, was inaugurated. These ships tried to carry out raids on the Pakistani fleet, but were mistakenly hit and sunk by the Indian Air Force on 10 December 1971. The next major attack was launched on Mongla seaport. According to official figures from the Bangladesh Navy, a total of 334 sailors were involved with the newly created navy, with 22 being killed in action.
