Bir Shrestho Ruhul Amin was born in 1935 at Bagpanchra village under what is now Sonaimuri Upazila of Noakhali district.

At the start of Bangladesh Liberation War with Operation Searchlight, Amin immediately resigned from the Pakistan Navy, left PNS Comilla at Chittagong, and returned to his village.

Two of the warships of the Bangladesh Navy/Mukti Bahini named Padma and Palash mistakenly came under fire from the Indian Air Force as it crossed the river Rupsha near the Khulna shipyard.

According to some other witnesses, Indian Air Force fired at different places of Khunla city earlier that day and incidentally one of those bombs had fallen at the warship Palash.

But the engine room was under fire again and another shell exploded which injured Ruhul Amin which convinced him to abandon the ship.
