"First Sacred War"@en . . "Kirrha" . . "The First Sacred War or Cirraean war, was fought between the Amphictyonic League of Delphi and the city of Kirrha. The conflict arose due to Kirrha's frequent robbery and mistreatment of pilgrims going to Delphi and their encroachments upon Delphic land. The war resulted in the defeat and destruction of Kirrha. The war is notable for the use of chemical warfare at the Siege of Kirrha, in the form of hellebore being used to poison the city's water supply."@en .
