The camp detachment at the time of the attack consisted of about 250 personnel drawn from the 6th battalion,
Gajaba Regiment (
commanding officer,
Lieutenant Colonel Kamal Gunaratne) and the
Sri Lanka National Guard with Captain Sudath Dabare serving as
officer commanding. They lacked any heavy weapons or armor. A large force of around 500 LTTE militants attacked in the early hours of 7 March taking control of the western half of the Valaiyiravu bridge and all defensive bunkers approach path from Vavunathivu junction. The military camp was located 150m from the approach road and the soldiers withdrew before the bridge was blown up. The camp was under heavy shelling from
81mm mortars and a
85 mm field artillery gun which the LTTE had captured during the
Battle of Pulukunawa. The LTTE used suicide cadres to attack the defense perimeter of the camp in waves and managed to breach it by mid day and the LTTE militants entered the camp. The defending troops withdrew to secondary defense positions and continued fighting as some these positions and buildings in the camp fell. Captain Dabare, wounded in both eyes rallied the defense and launched a counter attack with the remaining troops. He was able to hold out until reinforcement under Major Saman Wedagama reaching the besieged camp by boat with the support of
Mi-24 helicopter gunships the next day and the LTTE withdrew. Reinforcements from the brigade headquarters had been delayed as the LTTE shelled it with 81mm mortars on the Buffalo island and by a
Black Tigers infiltration of the
SLAF China Bay which left a
Harbin Y-12 destroyed. == Aftermath ==
