Having secured his throne, he then planned his operations to conquer the north, which included not only Rajarata but numerous smaller semi-independent polities. The king's army consisted of '
chariots, troops anderal beasts for riders', soldiers and a number of
war elephants, as well as a number of monks (to advise the King) and a
relic placed in his spear for luck and blessings. In addition he was accompanied by the famed
Ten Giant Warriors who had been recruited from all over the island by his father Kavantissa – Nandhimitra, Suranimala, Mahasona, Theraputtabhya, Gotaimbara, Bharana, Vasabha, Khanjadeva, Velusamanna, and Phussadeva. The campaign saw Dutugamunu subduing a number of usurping Tamil rulers in the north (as many as 32, according to the Mahavamsa). Of particular interest is the
four-month siege of
Vijitanagara, where the defending Tamil troops are said to have used 'red-hot iron and molten pitch' On at least two occasions victory is attributed to the king's 'cunning' and the bravery of Kandula. The campaign reached a climax at the eastern gate of Anuradhapura, where Dutugemunu, riding Kandula, finally confronted the aged usurped king
Elara the Pious, on his own elephant Mahäpabbata, and slew him with a spear; the encounter is one of the most famous in Sri Lankan history. Dutugamunu's victory at Anuradhapura put him in the unprecedented position of ruling nearly the entire island of (Sri) Lanka. Despite this, however, his position was far from problem-free.
Elara the Pious, though an invading Tamil ruler from the Chola Empire of South India, was renowned for his just and righteous rule, and Dutugemunu went to great lengths to honor the memory of the old king: he cremated
Elara the Pious, built a tomb for his ashes, and decreed that all travelers passing by must dismount and pay their respects at the site. Furthermore, 'looking back upon his glorious victory, great though it was, [he] knew no joy, remembering that thereby was wrought the destruction of thousands of both enemies and his soldiers' This is attested to by the sheer number of religious foundations attributed to him by the chronicles (between 68 and 99), which include magnificent stupas, monasteries, and shrines. == Reign and construction work ==
