Second Anglo-Mysore War

Hyder Ali ruled Mysore (though he did not have the title of king). Stung by what he considered a British breach of faith during an earlier war against the Marathas, Hyder Ali committed himself to a French alliance to seek revenge against the British. Upon the French declaration of war against Britain in 1778, aided by the popularity of ambassador Benjamin Franklin, the British East India Company resolved to drive the French out of India by taking the few enclaves of French possessions left on the subcontinent.[2] The company began by capturing Pondicherry and other French outposts in 1778. They then captured the French-controlled port at Mahé on the Malabar coast in 1779. Mahé was of great strategic importance to Hyder, who received French-supplied arms and munitions through the port, and Hyder had not only told the British that it was under his protection, he had also provided troops for its defence. Hyder set about forming a confederacy against the British, which, in addition to the French, included the Marathas and the Nizam of Hyderabad.

The Battle of Pollilur, where the forces of Hyder Ali effectively used Mysorean rockets and Rocket artillery against closely massed British forces.

In July 1780 Hyder Ali invaded the Carnatic with an army of 80,000. He descended through the passes of the Eastern Ghats, burning villages as he went, before laying siege to British forts in northern Arcot. The British responded by sending a force of 5,000 to lift the sieges. From his camp at Arcot, Hyder Ali sent part of his army under the command of his eldest son, Tipu Sultan, to intercept a British force from Guntur, under the command of Colonel William Baillie, which had been sent to reinforce Colonel Hector Munro's army 233 kilometres (145 mi) to the north at Madras.[2] On the morning of 10 September 1780, Baillie's force came under heavy fire from Tipu's guns near Pollilur. Baillie formed his force into a long square formation and began to move slowly forward. However, Hyder Ali's cavalry broke through the formation's front, inflicting many casualties and forcing Baillie to surrender. Out of the British force of 3,820 men, 336 were killed. The defeat was considered to be the East India Company's most crushing loss in India up to that time. Munro reacted to the defeat by retreating to Madras, abandoning his baggage and dumping his cannons in the water tank at Kanchipuram, a small town some 50 kilometres (31 mi) south of Madras.[3] Naravane states in fact that it was a massacre with only 50 officers and 200 men taken prisoner, including Baille.[4]

Instead of following up the victory and pressing on for a decisive victory at Madras, Hyder Ali renewed the siege at Arcot, which he captured on 3 November. This decision gave the British time to shore up their defences in the south, and to despatch reinforcements under the command of Sir Eyre Coote to Madras.[3]

Coote, though repulsed at Chidambaram, defeated Hyder Ali three times in succession in the battles of Porto Novo, Pollilur and Sholinghur, while Tipu was forced to raise the siege of Wandiwash, and besieged Vellore instead. The arrival of Lord Macartney as governor of Madras in the summer of 1781 included news of war with the Dutch Republic. Macartney ordered the seizure of the Dutch outposts in India, and the British captured the main Dutch outpost at Negapatam after three weeks of siege in November 1781 against defenses that included 2,000 of Hyder Ali's men. This forced Hyder Ali to realize that he could never completely defeat a power that had command of the sea, since British naval support contributed to the victory.

Tipu also defeated Colonel Braithwaite at Annagudi near Tanjore on 18 Feb 1782.[4] This army consisted of 100 Europeans, 300 cavalry, 1400 sepoys and 10 field pieces. Tipu seized all the guns and took the entire detachment as prisoners. In December 1781 Tipu had seized Chittur from British hands. These operations gave Tipu valuable military experience. Both Hyder Ali and Tipu Sultan gained alliances with Ali Raja Bibi Junumabe II and the Muslim Mappila community and later met with Muslim Malay from Melacca under Dutch service.

During the summer of 1782 company officials in Bombay sent additional troops to Tellicherry, from whence they began operations against Mysorean holdings in the Malabar. Hyder Ali sent Tipu and a strong force to counter this threat, and the latter had pinned this force at Panianee when he learned of Hyder Ali's sudden death due to cancer. Tipu's precipitate departure from the scene provided some relief to the British force, but Bombay officials sent further reinforcements under General Richard Matthews to the Malabar in late December to relieve before they learned of Hyder Ali's death. When they received this news, they immediately ordered Matthews to cross the Western Ghats to take Bednore, to the extent that he felt compelled to do so despite a lack of sound military footing for the effort. He entered Bednore, which surrendered after Matthews drove Mysorean force from the ghats. However, Matthews had so overextended his supply lines that he was soon thereafter besieged in Bednore by Tipu, and forced to capitulate. Matthews and seventeen other officers were taken to Seringapatam, and from there to the remote hilltop prison of Gopal Drooge (Kabbal Durga) where they were seemingly forced to imbibe a lethal poison.[5]

On the east coast, an army led by General James Stuart marched from Madras to resupply besieged fortifications and to dispute Cuddalore, where French forces had arrived and joined with those of Mysore. Stuart besieged Cuddalore even though the forces were nearly equal in size. The French fleet of the Baillie de Suffren drove away the British fleet, and landed marines to assist in Cuddalore's defence. However, when word arrived of a preliminary peace between France and Britain, the siege was ended. General Stuart, who was engaged in disputes with Lord Macartney, was eventually recalled and sent back to England.

The British captured Mangalore in March 1783, but Tipu brought his main army over, and after recapturing Bednore, besieged and eventually captured Mangalore. At the same time, troops from Stuart's army were joined with those of Colonel William Fullarton in the Tanjore region, where he captured the fortress at Palghautcherry in November, and then entered Coimbatore against little resistance.

During this time, company officials received orders from company headquarters in London to bring an end to the war, and entered negotiations with Tipu. Pursuant to a preliminary cease fire, Colonel Fullarton was ordered to abandon all of his recent conquests. However, due to allegations that Tipu violated terms of the cease fire at Mangalore, Fullarton remained at Palghautcherry. On 30 January the garrison of Mangalore surrendered to Tipu, having lost half its number principally to starvation and scurvy.

The war was ended on 11 March 1784 with the signing of the Treaty of Mangalore,[4] at which both sides agreed to restore the others' lands to the status quo ante bellum. The treaty is an important document in the history of India, because it was the last occasion when an Indian power dictated terms to the Company.

The great advantage to Tipu was the psychological impact of his victory with the British. The mode of conclusion was highly satisfactory to him. The march of the Commissioner all the way from Madras to Mangalore seeking peace made Munro remark that such indignities were throughout poured upon the British "that limited efforts seemed necessary to repudiate the Treaty at the earliest time."

It was the second of four Anglo–Mysore Wars, which ultimately ended with British control over most of southern India. Pursuant to the terms of the Treaty of Mangalore, the British did not participate in the conflict between Mysore and its neighbors, the Maratha Empire and the Nizam of Hyderabad, that began in 1785. In Parliament, the Pitt administration passed the Pitt's India Act that gave the government control of the East India Company in political matters.[6]

A battle honour, Carnatic was awarded for two periods: 1780-1784, during the Second Anglo-Mysore War, when Hyder Ali threatened Madras; and 1790-1792, during the Third Anglo-Mysore War, up to the siege of Mysore. Originally awarded to three battalions of Bengal Native Infantry in 1829, it lapsed after their disbandment due to participation in the 1857 uprising. In 1889, it was awarded to twenty units of the Madras Presidency Army. The battle honour is considered repugnant, an official term of opprobrium used by the Government of India.[7]
