Indonesian National Revolution: 96 Indonesian including I Gusti Ngurah Rai were killed during the Battle of Margarana with Dutch forces.

The Indonesian National Revolution, also known as the Indonesian War of Independence, was an armed conflict and diplomatic struggle between the Republic of Indonesia and the Dutch Empire and an internal social revolution during postwar and postcolonial Indonesia. It took place between Indonesia's declaration of independence in 1945 and the Netherlands' transfer of sovereignty over the Dutch East Indies to the Republic of the United States of Indonesia at the end of 1949.

Lieutenant Colonel I Gusti Ngurah Rai was a National Hero of Indonesia who commanded Indonesian forces in Bali against the Dutch during the Indonesian War of Independence. He was killed in the Battle of Margarana.

The Battle of Margarana was fought between the Netherlands Indies Civil Administration (NICA) and the recently created, rebelling Ciung Wanara Battalion that occurred in Marga, in Bali, Indonesia.
