The IPKF withdrew in March 1990, and the Government sponsored peace talks with the LTTE broke down in June 1990. The first outbreak of violence was reported in Ampara and Batticaloa areas. Large numbers of police personnel were captured and slaughtered by the LTTE.
The presence of the Army in these areas was very limited in numbers and the camps located in Kalmunai, Kalavanchikudi and Kiran were under siege. Kalmunai camp was evacuated by sea before reinforcements arrived. A massive operation was launched to reinforce the other two camps. Two brigades were launched under the command of Brigadier R De S Daluwatte, the Area Commander for Ampara and Batticaloa, under the direction of the late Lt Gen Kobbekaduwa who was responsible for the operations in the Eastern Province. 1 Brigade Group was tasked to reinforce Kalavanchikudi camp held by a company of 6th Battalion, Sri Lanka Light Infantry, whilst the 3 Brigade Group was assigned to reinforce Kiran camp held by a company of 1st Battalion, The Gemunu Watch. In approximately one weeks time the two brigades were able to break the siege on the two camps. The soldiers of the two camps held on valiantly beating back several LTTE attacks and inflicting heavy casualties on the enemy. Hostilities also broke-out in the adjoining Trincomalee district and in the Northern Province during the same period. The situation in the Eastern Province was brought under control within a months time, and civil administration was restored.
The situation in the Northern province was different to what was in the east. The Army bases which existed in the north were Palaly, Jaffna Fort, Mankulam, Kokavil, Elephant Pass, Mullaithivu, Kilinochchi and Mannar.
Due to the presence of the IPKF and the subsequent peace talks, the numbers in the bases had been reduced and the perimeters in large camps like Palaly had been reduced. There was no depth to the defences of these camps. The nonexistence of a land route forced the Army to depend on the Air Force for troop reinforcements and combat supplies. The air strip in Palaly was directly under enemy fire. However the determined pilots of the Sri Lanka Air Force were able to bring in reinforcements despite a heavy volume of enemy fire. Operation JAYASHAKTI was launched to expand the Palaly camp in order to facilitate the unhindered landing of aircrafts.
