Polonnaruwa–Pagan War

Polonnaruwa victory Polonnaruwa–Pagan War were a series of successful military expeditions led-by Sinhalese king Parakramabahu the Great against the Bagon Kingdom between 1165 and 1181.

Narathu deprived the envoys of the King of Polonnaruwa, which caused tension between the Sinhalese and Burmese ruler, and thus Parakkamabahu I dispatched a naval fleet to conduct a military raid.

[2] The army's size is unknown, but it is recorded as containing a year's supply of grains, specially modified arrows, and Sri Lanka's fearsome war elephants.

[3] Despite setbacks en route, including the sinking of one ship and the loss of a few others, the army arrived at the city of Kusumiya (modern Pathein)[4] on the banks of the Bago river, and captured it.

A retaliatory raid is also thought to have launched by Parakramabahu in 1180, after Narapatisithu, the successor of Narathu imprisoned Sinhalese envoys, tradesmen, and a princess on her way to the Khmer Empire.
