The Travancore–Dutch War was a war between the Dutch East India Company (VOC) and the Indian kingdom of Travancore, culminating in the Battle of Colachel in 1741.
Causes
In the early 18th century, the Malabar Coast region of present-day Kerala was divided among several small chiefdoms. In the 1730s, Marthanda Varma, the ruler of Travancore, adopted an expansionist policy, and conquered several territories from these small states. This threatened the interests of the Dutch East India Company's command at Malabar, whose spice trade depended on procurement of spices from these states. The ruler of Deshinganad (present-day Kollam) requested the Dutch support against an impending attack from Travancore, stating that he would surrender to Marthanda Varma if the Dutch refused to help him.
The Dutch had monopoly contracts with the states of Peritally (Perakattavali or present-day Nedumangad), Eledattu Svarupam (present-day Kottarakkara), and Maruthurkulangara. After Travancore captured these states during 1733-1734, their procurement from these areas stopped completely, and the Dutch trade in Malabar suffered greatly. In 1736, Julius Valentyn Stein van Gollenesse, the Dutch commander at Kochi (Cochin)) requested Marthanda Varma to honour the Dutch monopoly contract with Peritally that had been signed in 1688. He pointed out that the Dutch had declined to join the expelled ruler of Peritally against Travancore, even though the ruler had offered his whole land to the Dutch for such support. In August 1736, Marthanda Varma agreed to send his envoys to meet the Dutch representatives, but refused to do so after these representatives reached the meeting place. Travancore continued to supply the black pepper from Peritally to other foreign traders. In September 1736, van Gollenesse requested the queen of Maruthurkulangara to honour her monopoly contract with the Dutch, but the queen refused to do so now that her state was under Travancore's suzerainty.
In January 1739, Gustaaf Willem van Imhoff, the Dutch Governor of Ceylon, visited Kochi to study the affairs of the Dutch command in Malabar on behalf of the Dutch East India Company's supreme government at Batavia. In his July 1739 report, van Imhoff noted that Marthanda Varma favoured the Company's competitors, and that his increasing power threatened the Dutch trade interests in the region. In another report, van Imhoff rejected a plan to pay market price for procurement of pepper, calling it unprofitable, and instead favoured military action to force the coastal rulers to fulfill their contract obligations. In a December 1739 report, van Imhoff wrote that the Dutch business in the region was in "complete ruin", and would have to be saved through "violent redress".
In 1739, the Dutch organised an alliance of the rulers of Kochi, Thekkumkur, Vadakkumkur, Purakkad, Kollam, and Kayamkulam. Meanwhile, the princess of Eledattu Svarupam escaped from imprisonment at Travancore, and reached Thekkumkur. Van Imhoff personally met Marthanda Varma, urging him to reinstate the princess, but Marthanda Varma refused the demand. Van Imhoff threatened to invade Travancore, but Marthanda Varma dismissed the threat, and replied that he had been thinking about invading Europe some day.
Initial Dutch successes
After the failure of negotiations with Marthanda Varma, the Dutch command at Malabar decided to declare war on Travancore, without obtaining permission or waiting for reinforcements from Batavia. The Dutch deployed a detachment of soldiers from Ceylon against Travancore, under the command of Captain Johannes Hackert. They asked Marthanda Varma to vacate the lands annexed by Travancore, which the king refused to do. On 12 November 1739, a joint force of the Dutch and their allies attacked the Travancore army stationed near Kollam. The Dutch allies included Deshinganad, Kayamkulam, and Cochin. In the ensuing battle, a hand grenade exploded the gun powder depot of the Travancore army, which fled from the site, pursued by the attackers until Tangasseri (Quilon de Sima). At Tangasseri, which had been deserted, the Dutch captured 16 cannons, before marching to Paravur. The British East India Company (EIC) factor at Anchuthengu congratulated the Dutch on their victory and requested them to leave the EIC factory at Edava in peace.
By early December 1739, the Dutch and their allies marched towards Attingal and Varkala. The Travancore forces set up a stockade guarded by 5,000 Nair soldiers to guard Varkala. Meanwhile, the armies of Kollam and Kayamkulam also marched against the defenders. When the Travancore army withdrew to check an invasion by Chanda Sahib of Arcot in the south, the allies occupied Eledattu Svarupam, and reinstated the princess. Next, the allies attacked Attingal, but the Travancore army forced them to retreat. The Dutch decided to wait for reinforcements from Ceylon before waging further war against Travancore. As a result, the allies withdrew to Ayiroor, plundering and burning the territory on their way back.
Subsequently, the Nair army of Kollam forced the Travancore army to retreat from Navaikulam (30 December 1739) and Attingal (25 January 1740). On 20 February 1740, the Dutch and their allies defeated the Travancore army at the Attingal ferry, but took heavy losses; Kollam suffered the loss of half of their army, which, along with the forces of Kayamkulam, fled from the battlefield. Travancore had received the temporary aid of 150 soldiers, as well as guns and ammunition from the EIC factor at Anchuthengu, until the allied forces retreated. In the crisis after the battle, the Dutch pressured the distraught ruler of Kollam into assembling a new army of 10,000 Nair soldiers so that Travancore could not take advantage of the situation. Meanwhile, Marthanda Varma suffered reverses against Chanda Sahib at Thovalai. The Dutch hoped to press their advantage by attacking Attingal, but they were unable to receive reinforcements from Batavia because of the riots there.
Travancore's victory at Colachel
In November 1740, the Dutch command in Malabar received two small reinforcements of 105 and 70 soldiers from Ceylon, and launched a second campaign against Travancore, resulting in the battle of Colachel.
Marthanda Varma then captured the Dutch forts in the vicinity. A Dutch force under the command of De Lennoy landed at Colachel from Cochin and captured the country up to Kottar. Marthanda Varma marched south and prevented the capture of Kalkulam by the Dutch. When the Dutch retreated to their base in Colachel, Marthanda Varma pursued them and caught up with them on 10 August 1741. In the battle of Colachel Marthanda Varma won a decisive victory over the Dutch and captured 24 officers including the commander De Lennoy. A pillar that celebrates the victory and gives details about the war still stands near the coast of Colachel. There are folk tales among the local Mukkuvar people about this war. The tale says among other things that the local Mukkuvar fishermen were asked to keep their catamaran oars in vertical position on the beach sand, with an inverted pot on top of it along the beach side, so that it looked like a long line of infantry with helmets stood along the beach in multiple rows. The fishermen also kept their oars on their shoulders so that they would appear like soldiers standing with their rifles. They were also instructed to make mock cannons using coconut trees as a diversion. The local fishermen co-operated extensively with the Travancori royal guards and captured the ship during this war.
Post-Colachel conflicts
Subsequently, the Dutch and Travancore agreed to a ceasefire, but the hostilities resumed after the two sides failed to reach an agreement. After being reinforced with a cavalry contingent from Tirunelveli, Marthanda Varma besieged the Kilimanoor fort held by the Dutch. While the siege was going on, the rulers of Kollam and Kayamkulam left the Dutch alliance, and concluded a secret agreement with Travancore. On 10 April 1742, the dejected Dutch then left the fort in haste, leaving behind their ammunition and provisions. The Dutch force, led by Captain Daniel Bergen and Jacob Hinderman retreated to Ayiroor, but was surrounded and attacked by the Travancore forces. The Dutch contingent was rescued by the ships sent by the Malabar command.
Meanwhile, the queen of the Eledattu Svarupam kingdom, who had been restored to the throne by the Dutch after being dethroned by Marthanda Varma, had become unpopular as a ruler. Her indifference to the administrative affairs had led to decay of the kingdom, and the Madampis and the Pillais were dissatisfied with her rule. The Dutch commissioners had proposed appointing a Kariyakkar (administrator) to govern the kingdom alongside the queen, but did not have resources to spare for the kingdom's defence. Taking advantage of this situation, Marthanda Varma invaded the kingdom's capital Kottarakkara, and conquered it, facing little resistance. The queen fled to the Kingdom of Cochin, and started living with her relatives at Karapuram, receiving a daily allowance of 45 fanams from the Dutch.
In a 17 April 1742 letter to Batavia, the Dutch commander van Gollenesse requested 2,000 soldiers from the Company's Supreme Government, stating that the Dutch were in a dire situation in Malabar. Van Gollenesse mentioned that the Europeans were deserting the Dutch forces, and the local allies were breaking away from the Dutch command in Malabar: the ruler of Purakkad had announced intentions to break his alliance with the Dutch, and the king of Tekkumkur as well as two princes of Cochin had disobeyed their orders.
Meanwhile, Marthanda Varma planned an attack on Kochi (Cochin). However, Duyvenshot, the former Dutch officer who had accepted his employment, advised him to conquer Kollam before besieging Kochi. While Duyvenshot had told Marthanda Varma that the Travancore forces would be able to capture Kollam, van Gollenesse believed that the fortifications at Kollam would be able to withstand a siege. The ruler of Kollam and Kayamkulam sought the Dutch support against Travancore: van Gollenesse refused to oblige, citing scarcity of soldiers and weapons. In June 1742, the Travancore army attacked Kollam, which was defended by Nair soldiers led by Achyuta Wariar. During the siege, the Dutch provided counsel, rice and ammunition to the ruler of Kollam. Marthanda Varma made several unsuccessful attempts to capture Kollam, Marthanda and ultimately withdrew after losing 6,000 soldiers in the conflict.
Attempts at peace
After Travancore's failure to capture Kollam, van Gollenesse again sought 2,000 soldiers from Batavia, mentioning that the number of soldiers required would rise to 5,000 if the ruler Kozhikode (the Zamorin of Calicut) joined the war.
By 1742, the Dutch command in Malabar had spent enormous amount of money for defending their allies against Travancore's aggression, but had not gained much from this investment. The lack of funds and support from Ceylon and Batavia prompted the Dutch to resume negotiations with Travancore. Marthanda Varma, who had not responded positively to the Dutch attempts at negotiations in the past, agreed to a peace treaty this time.
On 17 February 1742, Marthanda Varma offered peace to the Dutch on the following terms:
