The Aceh War, also known as the Dutch War or the Infidel War (1873–1914), was an armed military conflict between the Sultanate of Aceh and 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.
For much of the 19th century, Aceh's independence had been guaranteed by the Anglo-Dutch Treaty of 1819 and its status as a protectorate of the Ottoman Empire since the 16th century. During the 1820s, Aceh became a regional political and commercial power, supplying half of the world's pepper, which increased the revenues and influence of local feudal rajas. Growing European and American demand for pepper led to a series of diplomatic skirmishes between the British, French and Americans. During the reign of Sultan Tuanku Ibrahim (1838–1870), the Aceh Sultanate brought the regional rajas under its control and extended its domain over the east coast. However, this southward trend clashed with the northwards expansion of Dutch colonialism in Sumatra.
Following the 1869 opening of the Suez Canal and changing shipping routes, the British and Dutch signed the 1871 Anglo-Dutch Treaty of Sumatra which ended British territorial claims to Sumatra, allowing the Dutch a free hand within their sphere of influence in Maritime Southeast Asia while handing them the responsibility to check piracy. In return, Britain gained control of the Dutch Gold Coast in Africa and equal commercial rights in Siak. Dutch territorial ambitions in Aceh were fuelled by a desire to exploit its natural resources, especially black pepper and oil, and to eliminate an independent native state player. The Dutch also sought to ward off other rival colonial powers that had ambitions in Southeast Asia, particularly the British and the French.
The Dutch tried one strategy after another over the course of decades. In 1873 they tried a single rapid attack, but it failed. They then tried a naval blockade, reconciliation, concentration within a line of forts, then passive containment. They had scant success. Reaching 15 to 20 million guilders a year, the heavy spending for failed strategies nearly bankrupted the colonial government.
First Dutch offensive
In 1873, negotiations took place in Singapore between representatives of the Aceh Sultanate and the local American Consul over a potential bilateral treaty. The Dutch saw this as a violation of a prior agreement with the British in 1871 and used this as an opportunity to annex Aceh militarily. An expedition under Major General Johan Harmen Rudolf Köhler was sent out on 26 March 1873, which bombarded the capital Banda Aceh and was able to occupy most of the coastal areas by April. It was the intention of the Dutch to attack and take the Sultan's palace, which would also lead to the occupation of the entire country. The Sultan requested and possibly received military aid from Italy and the United Kingdom in Singapore. In any case the Aceh army was rapidly modernized and enlarged with figures ranging from 10,000 to 100,000. Underestimating the military abilities of the Acehnese, the Dutch made some tactical errors and sustained losses including the deaths of Köhler and 80 troops. These defeats undermined Dutch morale and prestige.
Forced to retreat, the Dutch imposed a naval blockade of Aceh. In an attempt to preserve Aceh's independence, Sultan Mahmud appealed to the other Western powers and Turkey for help but to no avail. While the American Consul was sympathetic, the American government remained neutral. Due to its weak position in the international political stage, the Ottoman Empire was impotent. Meanwhile, the British refused to intervene due to their relations with the Dutch while the French declined to respond to Mahmud's appeal.
Second Dutch offensive
In November 1873, a second expedition consisting of 13,000 troops led by General Jan van Swieten was dispatched to Aceh. The invasion coincided with a cholera outbreak which killed thousands on both sides. By January 1874, deteriorating conditions forced Sultan Mahmud Syah and his followers to abandon Banda Aceh and retreat to the interior. Meanwhile, Dutch forces occupied the capital and captured the symbolically important dalam (sultan's palace), leading the Dutch to believe that they had won. The Dutch occupiers then abolished the Acehnese Sultanate and declared Aceh to be annexed to the Dutch East Indies proper.
Following Mahmud's death from cholera, the Acehnese proclaimed a young grandson of Tuanku Ibrahim, named Tuanku Muhammad Daud Syah, as Sultan Ibrahim Mansur Syah (r. 1874–1903) and continued their struggle in the hills and jungle territory for ten years, with heavy casualties on both sides. Around 1880 the Dutch strategy changed, and rather than continuing the war, they now concentrated on defending areas they already controlled, which were mostly limited to the capital city (modern Banda Aceh), and the harbour town of Ulee Lheue. Dutch naval blockades succeeded in forcing the uleebelang or secular chiefs to sign treaties that extended Dutch control along the coastal regions. However, the uleebelang then used their newly restored revenues to finance the Acehnese resistance forces.
The Dutch intervention in Aceh cost the lives of thousands of troops and was a severe drain on the colonial government's financial expenditure. On 13 October 1880 the colonial government declared the war was over and installed a civilian government, but continued spending heavily to maintain control over the areas it occupied. In an attempt to win the support of the local Acehnese, the Dutch built the Masjid Raya Baiturrahman or Great Mosque in Banda Aceh as a gesture of reconciliation.
War began again in 1883, when the British ship Nisero was stranded in Aceh, in an area where the Dutch had little influence. A local leader asked for ransom from both the Dutch and the British, and under British pressure the Dutch were forced to attempt to liberate the sailors. After a failed Dutch attempt to rescue the hostages, where the local leader Teuku Umar was asked for help but he refused, the Dutch together with the British invaded the territory. The Sultan gave up the hostages, and received a large amount of cash in exchange.
The Dutch Minister of Warfare August Willem Philip Weitzel again declared open war on Aceh, and warfare continued with little success, as before. Facing a technologically-superior foe, the Acehnese resorted to guerilla warfare, particularly traps and ambushes. Dutch troops retaliated by wiping out entire villages and murdering both prisoners and civilians. In 1884, the Dutch responded by withdrawing all their forces in Aceh into a fortified line around Banda Aceh. The Dutch now also tried to enlist local leaders: the aforementioned Umar was bought with cash, opium, and weapons. Umar received the title panglima prang besar (Great war commander).
Umar instead called himself Teuku Djohan Pahlawan (Johan the Heroic). On 1 January 1894 Umar even received Dutch aid to build an army. However, two years later Umar attacked the Dutch with his new army, rather than aiding the Dutch in subjugating inner Aceh. This is recorded in Dutch history as "Het verraad van Teukoe Oemar" (the treason of Teuku Umar). From the mid-1880s, the Acehnese military leadership was dominated by religious ulema, including Tengku Chik di Tiro (Muhamma Saman), who propagated the concept of a "holy war" through sermons and texts known as hikayat or poetic tales. Acehnese fighters viewed themselves as religious martyrs fighting "infidel invaders". By this stage, the Aceh War was being used as a symbol of Muslim resistance to Western imperialism.
In 1892 and 1893 Aceh remained independent, despite the Dutch efforts. Major J.B. van Heutsz, a colonial military leader, then wrote a series of articles on Aceh. He was supported by Dr. Christiaan Snouck Hurgronje of the University of Leiden, then the leading Dutch expert on Islam. Hurgronje managed to get the confidence of many Aceh leaders and gathered valuable intelligence for the Dutch government on the activities of Indonesian Hajj pilgrims. His works remained an official secret for many years. In Hurgronje's analysis of Acehnese society, he minimised the role of the Sultan and argued that attention should be paid to the hereditary chiefs and nobles, the Ulee Balang, who he felt could be trusted as local administrators. However, he argued, Aceh's religious leaders, the ulema, could not be trusted or persuaded to cooperate, and must be destroyed. As part of a policy of divide-and-conquer, Hurgronje urged the Dutch leadership to widen the existing gulf between the Acehnese nobility and the religious leaders.
In 1898 Van Heutsz was proclaimed governor of Aceh, and with his lieutenant, later Dutch Prime Minister Hendrikus Colijn, would finally conquer most of Aceh. They followed Hurgronje's suggestions, finding cooperative uleebelang that would support them in the countryside and isolating the resistance from their rural support base. The Dutch formulated a new strategy of counter-insurgency warfare by deploying light-armed Marechaussee units and using scorched earth tactics. Van Heutsz charged Colonel Gotfried Coenraad Ernst van Daalen with breaking remaining resistance. G.C.E. van Daalen destroyed several villages, killing at least 2,900 Acehnese, among which were 1,150 women and children. Dutch losses numbered 26, and Van Daalen was promoted.
In 1903, the main secular Acehnese resistance leaders including Sultan Muhammad Daud, Tuanku Raja Keumala, Mahmud and Muda Perkasa capitulated. By 1904 most of Aceh was under Dutch control, and had an indigenous government that cooperated with the colonial state. The Dutch consolidated their control over Aceh by practising a policy of religious tolerance as a means of dissuading the Acehnese from taking up an armed struggle. Nevertheless, episodes of marked Dutch military cruelty still occurred during this period. Photographs of a Dutch slaughter in Koeto Reh village taken during a Dutch military expedition in Aceh's Gayo and Alas regions in 1904, for example, indicate that killings of large groups of civilians occurred on some occasions. Estimated total casualties on the Aceh side range from 50,000 to 60,000 dead, and over a million wounded. The destruction of entire communities also caused 10,000 Acehnese to flee to neighbouring Malaya.
In the Netherlands at the time, Van Heutsz was considered a hero, named the 'Pacifier of Aceh' and was promoted to become governor-general of the entire Dutch Indies in 1904. A still-existent monument to him was erected in Amsterdam, though his image and name were later removed, to protest his violent legacy. The Dutch establishment defended its actions in Aceh by citing a moral imperative to liberate the masses from the oppression and backward practices of independent native rulers that did not meet accepted international norms. The Aceh War also encouraged Dutch annexation of other independent states in Bali, Moluccas, Borneo and Sulawesi between 1901 to 1910.
Colonial influence in the remote highland areas of Aceh was never substantial, however, and limited guerrilla resistance led by religious ulema persisted until 1942. Unable to dislodge the Dutch, many of the ulema gradually discontinued their resistance. The region of Gayo remained a center of resistance as late as 1914. One intellectual Sayyid Ahmad Khan advocated discontinuing the "jihad" against the Dutch since the term was used to define military warfare against religious oppression.
Following the Aceh War, local Uleebelang or aristocracy helped the Dutch maintain control over Aceh through indirect rule. During the early 20th century, both Standard Oil and Royal Dutch Shell developed oil refineries to extract the province's substantial oil reserves. Despite the end of open conflict, popular Acehnese resistance against Dutch rule continued until the Japanese invasion of the Dutch East Indies in 1942. Throughout the early 20th century, Dutch citizens and personnel were targeted by sporadic suicidal attacks by Acehnese patriots influenced by the Hikayat Perang Sabil and other proscribed texts. This phenomenon was known as the Atjeh-moord or "Aceh murders" and forced the Dutch government to maintain substantial forces within the province.
Acehnese resentment was further stoked by a system of forced corvee labour where subjects were required to work on government roadwork projects for 24 days a year. By the mid-1920s, Aceh had reverted to a state of full-scale guerilla warfare. Following the Japanese invasion, the occupying Japanese forces were initially welcomed by Acehnese nationalist as liberators though differences led to protracted resistance by Islamic-inspired rebels, culminating in a rebellion at Bayu. During the Indonesian National Revolution following the Japanese surrender in August 1945, the aristocracy were targeted for retribution due to their collaboration with the Dutch and the region became a stronghold of Sukarno's Republicans. Due to the entrenched anti-colonial sentiment, the Dutch bypassed Aceh during their police actions from 1947 to 1948.
Following the Dutch transfer of sovereignty to Indonesia in August 1949, many Acehnese became dissatisfied with the policies of the Javanese-dominated central government in Jakarta and began agitating for autonomy. Grievances included Aceh's incorporation into the predominantly Christian Batak province of North Sumatra, its poor financial and political rewards within the unitary Indonesian Republic and the failure to implement sharia law. In 1953, these factors led to a short-lived rebellion by the Darul Islam movement under Daud Bereueh which was suppressed by the Indonesian armed forces though resistance continued inland until 1959 when the rebels succeeded in negotiating an autonomous status for Aceh. Despite this, many Acehnese and other Sumatrans resented key government and military positions being dominated by Javanese. The resulting rebellion led by Free Aceh Movement raged in the province until a peace treaty was signed between the Acehnese movement and Indonesian government following the Great Aceh Tsunami.
Dutch Kerkhoff Poucut Cemetery
Numerous Dutch casualties of the Aceh War are buried the Kerkhoff Poucut Dutch military cemetery located near the centre of Banda Aceh, next to the Tsunami Museum. The Kerkhoff Poucut is recorded as the largest Dutch military cemetery outside the Netherlands. There are around 2,200 graves of white Dutch soldiers as well as recruits from Ambon, Manado and Java, as well as several Dutch generals.
