"March of Public Peace Preservation" (; ), usually known as the "Thai Police's Honour Song" (; ) from its first verse, and also called the "March of the Royal Thai Police" (; ) or merely "Police March" (; ), is a well-known Thai patriotic song and march of the Royal Thai Police. The music was composed by Nat Thawarabut (à ¸Âà ¸²à ¸£à ¸ à ¸Âà ¸²à ¸§à ¸£à ¸Âà ¸¸à ¸Âà ¸£) and the lyrics, by Kaeo Atchariyakun (à ¹Âà ¸Âà ¹Âà ¸§ à ¸Âà ¸±à ¸Âà ¸Âà ¸£à ¸´à ¸¢à ¸Âà ¸¸à ¸¥), both from the government musical band Suntharaphon (à ¸ªà ¸¸à ¸Âà ¸Âà ¸£à ¸²à ¸ à ¸£à ¸Âà ¹Â)
Musician Charin Nanthanakhon (à ¸Âà ¸£à ¸´à ¸Âà ¸Âà ¸£à ¹ à ¸Âà ¸±à ¸Âà ¸Âà ¸Âà ¸²à ¸Âà ¸£) wrote in the column "Sixth Crossroad of Entertainment" (à ¸«à ¸Âà ¹Âà ¸¢à ¸Âà ¸Âà ¸±à ¸Âà ¹Âà ¸Âà ¸´à ¸Â), published in Siam Rath newspaper in 1996, that the march was composed around 1957 upon order of Police General Phao Siyanon (à ¹Âà ¸Âà ¹Âà ¸² à ¸¨à ¸£à ¸µà ¸¢à ¸²à ¸Âà ¸Âà ¸Âà ¹Â), Director General of the Police Department at the time being and infamous dictator. Siyanon requested that the song must prevail over the "March of the Royal Thai Army" (à ¸¡à ¸²à ¸£à ¹Âà ¸Âà ¸Âà ¸Âà ¸Âà ¸Âà ¸±à ¸Âà ¸Âà ¸Â). In the said article, Nanthanakhon also noted that Thawarakun told him playfully: "I didn't want to compose this song at all, Charin. I don't really like police. They always come to arrest me while I'm playing cards."
In spite of Thawarabut's personal feeling towards the Royal Thai Police, he and Atchariyakun completed the work quickly. Siyanon was very impressed by it, especially by the verse "Unavoidable is death, but unceasable is our bravery" ("à ¹Âà ¸Âà ¸´à ¸Âà ¸¡à ¸²à ¹Âà ¸¥à ¹Âà ¸§à ¸Âà ¹Âà ¸Âà ¸Âà ¸Âà ¸²à ¸¢ à ¸Âà ¸²à ¸Âà ¸´à ¸Âà ¸²à ¸¢à ¹Âà ¸Âà ¸²à ¹Âà ¸§à ¹Âà ¸¥à ¸²à ¸¢à ¸Âà ¸³à ¸£à ¸§à ¸Âà ¹Âà ¸Âà ¸¢"), to the extent that he awarded bundles of monies to them together with complimentary letters and his namecards on which he signed and wrote "For you. When you are caught playing cards, show this to the police."
