The Royal Netherlands East Indies Army was the military force maintained by the Kingdom of the Netherlands in its colony of the Dutch East Indies, in areas that are now part of Indonesia. The KNIL's air arm was the Royal Netherlands East Indies Army Air Force. Elements of the Royal Netherlands Navy and Government Navy were also stationed in the Netherlands East Indies.

The Korps Marechaussee te voet were a colonial gendarmerie of the Royal Netherlands East Indies Army (KNIL), principally used for counter-insurgency in the Dutch East Indies.

A general officer is an officer of high rank in the armies, and in some nations' air and space forces, marines or naval infantry.

Gotfried Coenraad Ernst "Frits" van Daalen was a Dutch military officer of the Royal Dutch East Indies Army who served as the Governor of Aceh from 1905 until 1908. During the Aceh War, van Daalen and his men were responsible for the Kuta Reh massacre, in which hundreds of men, women, and children were killed.

The Aceh War, also known as the Dutch War or the Infidel War (1873–1904), was an armed military conflict between the Sultanate of Aceh and the Kingdom of the Netherlands which was triggered by discussions between representatives of Aceh and the United States in Singapore during early 1873. The war was part of a series of conflicts in the late 19th century that consolidated Dutch rule over modern-day Indonesia.
