Hein ter Poorten (21 November 1887 – 15 January 1968) was a Dutch military officer. He was the commander of the Royal Netherlands East Indies Army in World War II. Ter Poorten was also Allied land forces commander in the American-British-Dutch-Australian Command on Java during early 1942. Early life Hein ter Poorten was born on 21 November 1887 in Buitenzorg (now Bogor) on Java, which was at the time part of the Dutch East Indies. He was the son of Franciscus Hendricus ter Poorten, a chief mate in the Government Navy, and of Clasina Ambrosina Kater. After having been sworn in as an artillery officer in 1911, he helped to found the army air force, and in 1919 began a course at the Hogere Krijgsschool staff college in the Netherlands. He was invested as a Knight of the Order of Orange-Nassau with swords for his part in the development of military aviation in 1911.

In January 1942, following the outbreak of war with Japan, Ter Poorten was appointed commander of land forces in the American-British-Dutch-Australian Command, a short-lived unified command of all Allied forces in South East Asia. By March, Ter Poorten became the de facto head of all Allied forces on Java, following rapid Japanese advances and the break-up of ABDACOM. It was left to him to unconditionally surrender the island to the Japanese on 8 March 1942. Ter Poorten had no authority to sign the surrender and did not initially do so. After threats and under pressure of reprisals, Ter Poorten was forced to read a statement on the radio about an unconditional capitulation. Van Mook had already been appointed Lieutenant Governor General on 1 January 1942 by the government in exile in London. In this position he
