Battle of Mullaitivu: The Liberation Tigers of Tamil Eelam capture the Sri Lanka Army's base, killing over 1,200 soldiers.

The Battle of Mullaitivu, also known as the First Battle of Mullaitivu and codenamed Operation Unceasing Waves-1, was a battle between the militant Liberation Tigers of Tamil Eelam and the Sri Lankan military during the Sri Lankan Civil War for control of the military base in Mullaitivu in north-eastern Sri Lanka.

The Liberation Tigers of Tamil Eelam was a Tamil militant organization, that was based in the northern and eastern Sri Lanka. The LTTE fought to create an independent Tamil state called Tamil Eelam in the northeast of the island in response to violent persecution and discriminatory policies against Sri Lankan Tamils by the Sinhalese-dominated Sri Lankan government.

The Sri Lanka Army is the oldest and largest of the Sri Lanka Armed Forces. The army was officially established as the Ceylon Army in 1949, though the army traces its roots back in 1881 when Ceylon Light Infantry Volunteers was created; the army was renamed as the 'Sri Lanka Army' when Sri Lanka became a republic in 1972. In 2024, the Army had approximately 150,000 personnel.
