The Liberation War of Bangladesh is a memorable event in our national lifE- She achieved her independence through sacrifice and bloodshed. It is the birthright of a man. On the night of March 25, 1971, the Pakistan army fell upon the unarmed sleeping Bangalees. But we were not cowards. They built up strong resistance against them. They fought with courage for long nine months. After nine months' bloody war and sacrifice of the freedom fighters, the red sun of independence rose in our soil on the 16th December, 1971. Now we remember them with great respect.
