Later, except for those who were present at the other rank's billet that stood closest to the police station at the time of the incident, all other personnel who were on compulsory leave were ordered to report for duty. Though moral had been badly affected they were reassured of service and their tribulations seemed to be over since they were recalled for duty. However, as troops reported to Echelon Square it was found difficult to provide them with meals since the kitchen was not permitted to be opened. Personnel from the Ceylon Corps of Military Police (CCMP) were deployed inside the camp ostensibly to have a close watch on Sinha Regiment personnel. To overcome the situation Lieutenant Colonel DW Hapuarachchi having discussed the matter with his officers made arrangements to serve a wholesome meal to all utilizing regimental resources. Further, all other ranks who reported back after compulsory leave were paid their monthly salary on 20th and 21st February 1981 at the Headquarters of the Sri Lanka Army Pioneer Corps.
By this time although the construction work on many of the buildings at Ambepussa had not been completed, the Battalion Headquarters and Headquarters Company were shifted to Ambepussa.

In the year 1981 the Government decided to hold the Independence Day celebrations it on 22nd March and the Battalion too was required to participate. Known among the public for its superb display of in Drill the Regiment had to live up to its reputation. The key to success being training as a team, the main obstacle for the Regiment was the scattered deployment of its troops. However, overcoming all such obstacles the performance of the Sinha troops once was of a very high standard.
Lieutenant Colonel DW Hapuarachchi who led the Battalion and rendering conscientious service faced many problems and difficulties which later forced him to leave the Army, the reason for leaving being rather ironical; the Language Act that was in force at the time. However, much doubt existed in the 'reason' that forced him to leave the Army when an Annual Confidential Report by his Commanding Officer raised somewhere in the early 60s at the time he was an Adjutant came to light. It mentioned that the Adjutant was an asset when implementing the state language policy and did a tremendous service to activate the State Language Act.
