In 1812 and 1813, theBritish colonial government in Java sent two military expeditions against theSultanate of Sambas in modernWest Borneo, with the first expedition being forced to retreat while the second expedition succeeded in capturing the town ofSambas. The expeditions were launched with the intent of suppressing pirate activity operating from Sambas, led by son of the Sultan Pangeran Anom. Although defeated, the Sultan of Sambas would reach a settlement with the British shortly after, with the Sultanate retaining its status. Pangeran Anom would also be pardoned by the British and later became sultan.
Following the1811 British invasion of Java, the status ofDutch colonies in the East Indies became tenuous. While the British militarily occupied Java, other islands were not under immediate control, including the island ofBorneo. Shortly after Java's fall, British colonial authorities there had begun communication with the sultanates of Borneo, starting withBanjarmasin in the south.[1] InWest Borneo, the primary polities were the Sultanates ofPontianak andSambas,[2] with the Dutch having reduced their presence in the region since the late eighteenth century.[3]
While Pontianak's sultan welcomed British protection and invited the British to station a garrison in Pontianak, Sambas did not reciprocate. Sambas at the time was a centre of pirate activity, with government being run largely by Pangeran (Prince) Anom, son of the old Sultan of Sambas Abubakar Tadjuddin I.[2][4] Anom was active in piracy, with British sources describing him as "having out-herodedHerod in his atrocities".[5] The British estimated that Sambas was able to muster a force of ten to twelveproa with seventy to eighty armed men each.[6] In 1812, Anom captured the Portuguese merchant vesselCoromandel and nine crewmembers of the British sloopHecate, which led the British to prepare a military expedition against Sambas.[6]
The first expedition to Sambas was launched in October 1812, led by Captain J. Bowen aboard the frigateHMSPhoenix along with thesloops-of-warProcris andBarracouta. The ships also carried around 100 soldiers of the78th Regiment.[5][6] The force was tasked with destroying the town of Sambas, but British leadership assumed that the attacking force would be sufficient to intimidate the defenders into capitulating.[2] Upon arrival at Sambas, the defenders did not capitulate, and theBarracouta came under fire from both pirate ships and from shore-bound guns which inflicted some casualties. Unable to flank the defenders and lacking men for an amphibious assault, Bowen retreated and returned to Java.[2][6]
The failed expedition caused significant embarrassment to British authorities in Java, but due to a lack of available resources, there were no immediate follow-up expeditions in 1812.[2] TheBombay Marine sloop-of-warHCSAurora blockaded theSambas River after the failed expedition to prevent raiding in the meantime.[6] The blame for the failure generally fell on Bowen,[5] and officials generally covered up details of the failure.[8] Bowen fell ill and died not long after his return from the expedition.[6]

To "vindicate the honour of the British flag",[6] the British planned and prepared for a second expedition throughout early 1813, with a much larger force. The naval contingent consisted ofRoyal Navy frigatesLeda,Hussar,Malacca, andVolage, sloopsHecate andProcris,East India Company warshipsAurora,Malabar,Teignmouth, and five other gunboats plus two transport ships. The squadron's senior officer was CaptainGeorge Sayer aboardLeda.[6] The land force consisted of between 700 and 800 British troops of the14th Regiment under ColonelJames Watson and 600Sepoy troops of theBengal Army. The force embarked on 23 June and arrived at the mouth of the Sambas River on 25 June.[9] The troops sailed up the river, disembarked on 26 June, and divided into three columns.[10]
The town of Sambas was defended by a number of cannon-armed emplacements, and at 3 AM on 28 June the British commenced their attack.[10] After a half-hour battle, the emplacements were taken and the defenders were in retreat, with Pangeran Anom managing to escape the town into the interior of Borneo.[11] According to British sources, the attacking force suffered 7 or 8 killed, with 59 wounded.[10][11] The British estimated Sambas' losses at 150 killed including a brother of Sambas' sultan and a son of Pangeran Anom, with 31 brass cannons and 36 iron cannons also captured.[10] TheCoromandel was also taken by the British along with the fleet of pirate vessels at Sambas. Sambas was occupied by the British without further resistance.[12]
While the British did not suffer many casualties in combat, tropical diseases inflicted significant losses on soldiers stationed at Sambas and to marine crews. Two-thirds of the 75 European crewmen of the sloopTeignmouth, for instance, died of fever during the expedition and occupation.[12] In September 1813, the British announced an amnesty and restoration for the Sultan of Sambas conditional on the acceptance of a British resident, which was accepted and a treaty between Sambas and the British was signed on 24 October 1813.[13] The Sultan also agreed to cease sheltering pirates within Sambas.[14] Another pardon was issued to Pangeran Anom in August 1814, and he would succeed as Sultan Muhamad Ali Sjafiudin of Sambas after his father's death in 1815.[4][15]
