After the capture of _Onore_, Brigadier-General Mathews, in pursuance of his orders, proceeded further down the coast, and took the towm of Cundapore with little loss. He subsequently forced a passage through the Ghauts, and the rich Canara kingdom, with its capital, now lay open to the invaders. The city of Bednore had recently changed its name to Hyder Nagur, or the Royal City of Hyder. The government and command of the city and country were lodged in the hands of Hyat Saib, who surrendered the place to the British, after an action had taken place at the Hussanghurry Ghaut. This occurred early in February 1783; and on the 9th of March _Mangalore_ fell into the hands of the British. Tippoo Saib, who had now succeeded to the title of Sultan, determined to use every effort for the recovery of these favorite possessions. Having recovered Bednore, which surrendered on the 28th of April, the Sultan, in defiance of the terms of the capitulation, ordered Brigadier-General Mathews and his officers into close confinement, from which they never returned, being afterwards put to a violent death. Tippoo next proceeded to invest _Mangalore_, on the Malabar coast, and it required all the abilities of Lieut.-Colonel John Campbell, major of the _Forty-second_, seconded by the well-tried valour of the second battalion of that regiment, and other corps, to supply the defects of the fortifications. The place was invested on the 18th of May by the whole of the enemy’s forces, commanded by Tippoo in person. The garrison under Lieut.-Colonel Campbell (Colonel Macleod being employed as a Brigadier-General), made a most gallant and successful defence, subject to hardships and wants which have seldom been exceeded in the annals of sieges. In consequence of the General Peace which had been entered into with the European Powers, Tippoo became deprived of his French allies, and the Sultan entered into negociations for terminating the war between Mysore and the British, when an armistice took place. This event terminated the siege of _Mangalore_ about the end of September, at a time when all the works which defended the garrison were nearly shattered to pieces; all the provisions exhausted, and numbers of the brave soldiers were dying daily, victims of want and disease.[6] The contest was, however, again renewed, and the garrison was a second time invested by Tippoo. [Sidenote: 1784] The fortress of _Mangalore_ was defended until the 25th of February 1784, when sickness, and the want of provisions, compelled Lieut.-Colonel Campbell to evacuate the place, after obtaining the most honorable terms from the enemy. Peace was afterwards concluded with the Sultan of Mysore on the 11th of March following. The battalion embarked in this year for Calcutta, and was employed on active service in the Upper Provinces of Bengal. [Sidenote: 1786]
