Since resumption of violence, concerns were mounting among ಸೇನೆ establishment that strategically crucial ಶ್ರೀಲಂಕಾ Navy base in Trincomalee was under grave threat from ಎಲ್‍ಟಿಟಿಇ gun positions located in ಮತ್ತು around Sampur, which lies across Koddiyar Bay from Trincomalee. Artillery fired from ಎಲ್‍ಟಿಟಿಇ bases in area could potentially cripple naval base, bringing it to complete standstill ಮತ್ತು therefore cutting only ಸೇನೆ supply chain to Jaffna. All ಚಳುವಳಿs of naval vessels were also under constant surveillance of ಎಲ್‍ಟಿಟಿಇ. These fears were backed up by United States ಸೇನೆ advisory team which visited ದ್ವೀಪ in 2005.

Following clashes in Mavil Aru (Mavil Oya) ಮತ್ತು Muttur (Mooduthara), ಎಲ್‍ಟಿಟಿಇ had intensified attacks targeting naval base in Trincomalee (Gokanna), ಮತ್ತು in speech on August 21, ಶ್ರೀಲಂಕಾದ president Mahinda Rajapakse made clear ಸರ್ಕಾರ intentions were to neutralize ಎಲ್‍ಟಿಟಿಇ threat from Sampur. On August 28, ಶ್ರೀಲಂಕಾದ ಸೇನೆ launched assault to retake ಎಲ್‍ಟಿಟಿಇ camps in Sampur ಮತ್ತು adjoining Kaddaiparichchan (Gaeta-bara-hena)ಮತ್ತು Thoppur (Thupapura) areas. This led ಎಲ್‍ಟಿಟಿಇ to declare that if ಆಕ್ರಮಣ continued, ಕದನ ವಿರಾಮ would be officially over.

After steady progress, ಶ್ರೀಲಂಕಾದ security forces led by Brigade Commander Sarath Wijesinghe re-captured Sampur (Somapura) from ಎಲ್‍ಟಿಟಿಇ on September 4, ಮತ್ತು began to establish ಸೇನೆ bases there, as ಎಲ್‍ಟಿಟಿಇ admitted defeat ಮತ್ತು stated their cadres "withdrew" from strategically important town. It marked ಮೊದಲ significant territorial change of hands since signing of ಕದನ ವಿರಾಮ agreement in 2002. The ಶ್ರೀಲಂಕಾದ Military estimated that 33 personnel were killed in ಆಕ್ರಮಣ, along with over 200 ಎಲ್‍ಟಿಟಿಇ cadres.
