The Third Anglo-Mysore War (1789–1792) was a military conflict in Southern India between the Sultanate of Mysore and the East India Company, Maratha Empire, Kingdom of Travancore and the Nizam of Hyderabad. It was the third of four Anglo-Mysore Wars.
Background
Tipu Sultan, the ruler of the Kingdom of Mysore, and his father Hyder Ali before him, had previously fought twice with the forces of the British East India Company. The First Anglo-Mysore War, fought in the 1760s, had ended inconclusively on both sides, with treaty provisions including promises of mutual assistance in future conflicts. British failure to support Mysore in conflicts with the Maratha Confederacy and other actions supportive of Mysore's enemies led Hyder to develop a dislike for the British.
After the British took the French-controlled port of Mahé in 1779, Hyder, who had been receiving military supplies through that port and had placed it under his protection, opened the Second Anglo-Mysore War. This war ended with the last British–Indian treaty with an Indian ruler on equal footing, the 1784 Treaty of Mangalore, which restored the status quo ante bellum under terms company officials such as Warren Hastings found extremely unfavourable for the British East India Company. Tipu, who gained control of Mysore after his father's death in December 1782, maintained an implacable hatred of the British, and declared not long after signing the 1784 treaty that he intended to continue battle with them given the opportunity. He refused to free British prisoners taken during the war, one of the conditions of the treaty. Tipu Sultan further strengthened his alliances with Ali Raja Bibi Junumabe II the Muslim ruler and the Mappila Muslim community of a region under the Zamorin of the Calicut empire, thus expanding the Sultanate of Mysore's sphere of influence.
British General Charles, 2nd Earl Cornwallis became the Governor-General of Bengal and Commander-in-Chief for the East India Company in 1786. While he formally abrogated agreements with the Marathas and Hyderabad that violated terms of the 1784 treaty, he sought informally to gain their support and that of the Nizam of Hyderabad, or at least their neutrality, in the event of conflict with Mysore.
Also, Pitt's "India Act" came into force in 1784, which made East India Company subordinated to the British crown, making the Company's power insignificant and marking the rise of direct British imperial control in India. Thus, unlike the earlier wars, where Tipu and his father confronted the Company, Tipu would now be fighting, in effect, against the British Empire.
Events leading to war
In 1788, the company gained control of the Circar of Guntur, the southernmost of the Northern Circars, which the company had acquired under earlier agreements with the Nizam. In exchange, the company provided the Nizam with two battalions of company troops. Both of these acts placed British troops closer to Mysore, but also guaranteed the Nizam would support the British in the event of conflict.
Travancore had been a target of Tipu for acquisition or conquest since the end of the previous war. Indirect attempts to take over the kingdom had failed in 1788, and Archibald Campbell, the Madras president at the time, had warned Tipu that an attack on Travancore would be treated as a declaration of war on the company as per the Treaty of Mangalore. The rajah of Travancore also angered Tipu by extending fortifications along the border with Cochin into territory claimed by Mysore as belonging to its vassal state, and by purchasing from the Dutch East India Company two forts in the Kingdom of Cochin, a state paying tribute to Tipu Sultan.
In 1789 Tipu Sultan sent forces onto the Malabar Coast to put down a rebellion. Many people fled to Travancore, a state independent of Mysore and to Cochin, a state paying tribute to Tipu, in the wake of his advance. To follow them, Tipu began in the fall of 1789 to build up troops at Coimbatore in preparation for an assault on the Nedumkotta, a fortified line of defence built by Dharma Raja of Travancore to protect his domain. Cornwallis, observing this build-up, reiterated to Campbell's successor, John Holland, that an attack on Travancore should be considered a declaration of war, and met with a strong British response. Tipu, aware that Holland was not the experienced military officer that Campbell was, and that he did not have the close relationship that Campbell and Cornwallis had (both had served in North America in the American Revolutionary War), probably decided that this was an opportune time to attack.
Early campaigns
On 29 December 1789, Tipu marched 14,000 troops from Coimbatore and attacked Nedumkotta. The first phase was a defeat for Tipu, when the Travancore forces under Kesava Pillai inflicted severe losses on the Tipu's forces and drove them back. While the Mysorean forces and their allies regrouped, Governor Holland, much to Cornwallis' dismay, engaged in negotiations with Tipu rather than mobilising the military. Cornwallis was on the brink of going to Madras to take command when he received word that Holland's replacement, General William Medows was about to arrive. Medows forcibly removed Holland, and set about planning operations against Tipu while building up troops at Trichinopoly.
Medows' campaign, 1790
It was May before Medows was prepared to march. In the meantime, Tipu had renewed his attack on Travancore, and successfully breached the Nedumkotta line in late April 1790, despite the heavy losses inflicted by the Tranvancorean army. The Travancorean army made a strategic retreat to the further bank of the Periyar River and regrouped, preparing to contest the crossing of the river. The monsoon rains prevented the Mysorean army from fording the river and as Tipu received the news that the British campaign from Madras began to take shape as a significant threat, he retreated from Travancore.
The plan of attack developed by Medows called for a two-pronged attack, with the main thrust against the Coimbatore district and a diversionary thrust into Mysore from the northeast. Cornwallis was unhappy with this plan, due in part to the lateness of the season (combat being much more difficult during the monsoon season), and the lengthy supply lines from Madras that the plan entailed. However, he was willing to give Medows the opportunity for independent command.
Medows moved out of Trichinopoly in late May. Hampered by weather and equipment problems, his progress was slow. He met little resistance, as Tipu had withdrawn his main forces to the Mysore highlands. On 21 July, Medows entered Coimbatore unopposed, after having taken some of the smaller fortifications in the district by either abandonment or the immediate surrender of the garrison. His only opposition consisted of 4,000 cavalry under Sayed Sahib that Tipu had detached to observe and harass his operations; most of these were eventually driven across the Bhavani River by Medows' cavalry. Further strong points in the district fell, with Palghat and Dindigul requiring significant action to capture.
Although the campaign was successful in gaining complete control of the Coimbatore district, Medows had to divide his forces to hold it, with the largest detachments at Coimbatore, Palghat, and Sathyamangalam. The attack from Bengal, and a third from Bombay, were late in getting started when Tipu made his counterattack.
Tipu's counterattack
On 2 September, Tipu left Srirangapatnam at the head of a 40,000-man army. Descending the mountain passes beginning on 9 September, he began to move toward Sathyamangalam. While the 2,800-man garrison there withstood an initial assault from Tipu's force on 13 September, Captain John Floyd, the garrison commander, opted to withdraw. Under cover of night, they crossed the Bhavani and headed for Coimbatore. Tipu, slowed by heavy rains, sent 15,000 cavalry in pursuit. These eventually caught up and captured much of Floyd's baggage train, and continued to pursue the weary garrison. That evening, the full force of Tipu's army fell upon them as they camped at Cheyoor. A desperate stand by the infantry repulsed repeated assaults, and only the arrival of reinforcements sent by Medows rescued them.
Tipu then embarked on a campaign of harassing the British supply and communications, while screening the movements of his main force. In early November, he successfully misled Medows, moving much of his army north to attack the smaller Bengal force. This force, about 9,000 men led by Colonel Maxwell, had reached Kaveripattinam and strongly fortified his position. Unable to penetrate the defences, Tipu withdrew to the south on 14 November after learning that Medows was on his trail again. Medows and Maxwell joined forces on 17 November, and pursued Tipu, who had decided to make a move toward Trichinopoly. Unable to do more than pillage the town before Medows arrived, Tipu then moved on to rampage through the Carnatic, destroying towns and seizing supplies as he went. He ended up at the French outpost at Pondicherry, where he attempted to interest the French in supporting his efforts against the British. As France was then in the early stages of its revolution, these efforts were entirely unsuccessful. Medows at this point moved toward Madras, where he turned over command of his army to Lord Cornwallis.
Allied advances
During the summer of 1790, a Maratha army of some 30,000 under the command of Purseram Bhow, accompanied by a detachment of British troops from Bombay, began marching toward Mysore. The first several Mysorean outposts surrendered in the face of the large army, and it made steady if slow progress until it reached Darwar in September. The fort was weakly and indifferently besieged for 29 weeks, with the garrison finally surrendering on 3 April 1791. The army then continued to advance, reaching the Tungabhadra River in early May.
A second army, consisting of 25,000 cavalry and 5,000 infantry under the command of Hurry Punt assisted by a detachment of British soldiers from the Madras army, left Poona in January 1791, eventually reaching Kurnool without significant opposition. Hurry Punt went to confer with the Nizam, who had not crossed into Mysore in fear that Tipu's large army would overwhelm his before it could be joined to that of one of the other allies. On receiving word that Cornwallis had captured Bangalore and was moving toward the Mysorean capital, Srirangapatnam, Hurry Punt moved out from Kurnool, and made junction with Cornwallis on 28 May.
The Nizam's army, led by Mahabat Jung, advanced to Koppal, which they besieged in October 1790. Poor-quality cannons impeded the conduct of the siege, which was not successfully concluded until April 1791.
British take the Malabar Coast
British forces succeeded in taking control of the Malabar Coast late in 1790. One force under Colonel Hartley gained a decisive victory at Calicut in December, while a second under Robert Abercromby routed the Sultan at Cannanore a few days later.
Nawab of Savanur
Territory associated with the Nawab of Savanur were lost to the Maratha Confederacy. Such events caused mistrust between the English and the agenda of the Peshwa.
First advance on Seringapatam
Cornwallis' first goal was to take the strong point of Bangalore, which would provide a base for future operations against Seringapatam. He hoped that this would stimulate the allies to step up their activity. Anticipating that Tipu would engage in a scorched-earth campaign in the highlands of Mysore, he made significant arrangements for provisions. To assist in the hauling of supplies and heavy armaments he also retained a significant number of elephants.
