From 1832 to 1950 a substantial colonial army was maintained in the Dutch East Indies under the title of the Royal Netherlands East Indies Army. Following Indonesian independence the Dutch and indigenous personnel of this force were demobilised but with the establishment of the Regiment van Heutsz on July 1, 1950 the traditions and distinctions of the KNIL were transferred to the new regiment. These included the inscription 'Military Operations Royal Dutch East Indies Army 1832-1950', still carried on the banner of the regiment.
Korean War
The van Heutsz Regiment was incorporated into the Nederlands Detachement Verenigde Naties , which also included the Dutch Naval component sent to Korea. While 16,225 people volunteered for service in Korea, only 3,418 men were accepted and sent. 2,980 of those participated in the actual war, as the units that arrived after the armistice did not participate in any fighting. The van Heutsz regiment had only recently been raised when the Korean War battalion was formed on October 26, 1950, but took the detachment as its first battalion. The regiment has the battle honorKorea 1950–1954 on its colors. In Korea, the van Heutsz troops were re-enforced by South Korean "KATUSA" troops. The Dutch served at three key battles, all around the Iron Triangle sector between 1951 and 1953. Since the Regiment van Heutsz did not have its colors in 1950, a Dutch flag that was used in Korea as the battle flag of the Nederlands Detachement Verenigde Naties became the regimental colour. This flag now has official status and is shown on every parade and function of the regiment. American and Korean battle streamers, representing the US Presidential Unit Citation, are attached to this flag. The Regiment suffered 116 Dutch and 20 attached-Korean soldiers killed in action, three soldiers are still MIA, while one Dutchman was taken prisoner and died in a North KoreanPOW camp. The Dutch casualties are buried at the United Nations Memorial Cemetery in Busan, including their commander, Lt. Col. :nl:Marinus Petrus Antonius den Ouden|Marinus Petrus Antonius den Ouden, who was killed in action during the Battle of Hoengsong in February 1951. A total of 381 soldiers were wounded. A total of 115 Surinamese soldiers also fought together with the Dutch, at least two died.
