LTTE
Deeply affected by the suffering of the victims of Black July anti-Tamil riots, Vasanthan joined the militant Liberation Tigers of Tamil Eelam in 1983 as driver. He became a full time member of the LTTE a year later. He was given the nom de guerre Miller. During the Vadamarachchi Operation the Sri Lanka Army took over Nelliady Madhya Maha Vidyalayam and turned it into a military base. The LTTE resolved to capture the base which was heavily reinforced and surrounded by barbed wire. Miller volunteered to drive a bomb filled vehicle into the heart of the base. Miller visited his family on 29 June 1987 and treated them and his friends to ice cream. On 5 July 1987 the LTTE filled a truck with explosives and wedged Miller's body into the driver's seat so that he couldn't move even if he wanted to. His hands were tied to the steering wheel and one foot to the accelerator. Fellow LTTE cadres started the truck which started moving. Miller steered the explosive filled truck into the army camp at Nelliady Madhya Maha Vidyalayam. Miller was most likely killed at the first barricades when soldiers opened fire but the truck kept going, ramming into the main school building and exploding. The explosion created a crater as big as a bus. Other LTTE cadres who were following Miller's truck launched an attack on the camp and captured it. Scores of soldiers were killed and wounded. The incident was videotaped and Miller was posthumously promoted to captain. He became a revered figure in the LTTE and his face was on the insignia of the Black Tigers, the LTTE's suicide wing. 5 July became Karumpuli Naal, a day for Tamils across the world to commemorate all Black Tiger "martyrs". A shrine, including a golden statue of Miller, was built at Nelliady Madhya Maha Vidyalayam. After the Sri Lankan military re-captured the Vadamarachchi region in 1996 they destroyed Miller's shrine but locals managed to save and hide his statue. The statue and new memorial plaque were re-installed in 2002 during the Norwegian mediated Cease Fire Agreement. After war resumed, Miller's statue was attacked and destroyed by armed men on 23 August 2006. The remnants of the shrine - the dais on which Miller's statue stood and stone memorial plaque - were destroyed by the army on 4 July 2010.
