Liberation War of Bangladesh

The defense having dug in, the troops were in position by March 30. The company at the advanced position located itself in the Ispahani buildings about a mile to the west bank of the river. Some troops were also located on the west bank as a measure of providing, besides moral support , active physical support to the advance position. Harun, Shamsher Mobin and Lieutenant Mahfuz stayed on the west bank with some troops.
A platoon of 3 commando battalion advanced on Kalurghat and occupied the Agriculture building on Karnaphuli about a mile to the south. It was early morning on March 31, Mahfuz was ordered to dislodge the enemy. He conducted with his platoon a daring raid and successfully captured the building.
The battle of Kalurghat continued sporadically and several times enemy attempts at capturing the bridge were foiled courageously. Shawkat at times took out strong ambush parties himself and always kept the enemy foxed and contained. He carried about himself a style of his own. A strong believer in fire power, he did not hesitate to take out even suicide parties only after he was amply sure that the party had all the fire power at his command.
