The work commenced at 8 pm on December 15 and was carried out under intense Pakistani small arms, tanks and artillery fire. The Task Force, under Maj VR Choudhary, was deployed for breaching minefield and constructing a passage for tanks and other vehicles through the river Basantar in Lagwal area. On reaching the obstacle at about 8.30 pm, the Task Force found the situation very confusing on account of intense shelling and small arms fire which was further aggravated because of scanty information about the obstacle itself. As conventional reconnaissance would have taken considerable time, the Task Force Commander decided to disregard normal drills and safety precautions and to send a small party on a wide frontage at normal walking speed.
