to Seringapatam when it was established that one of its officers was fighting in violation of a parole agreement. After rapidly establishing control over much of the southern Carnatic, his march turned toward Madras. This prompted the British to send an envoy to discuss peace; because of Hyder's insistence that the nawab of the Carnatic be excluded from the negotiations, they went nowhere. Hyder then surprised company authorities by taking a picked force of 6,000 cavalry and a small number of infantry, and made a three-day forced march of to the gates of Madras. This show of force compelled the company to negotiate further, since Madras had been left nearly defenceless by military movements made to counter those of Hyder's main force. Hyder, who was seeking diplomatic leverage against the Marathas, wanted an alliance of mutual defence and offence. The company refused to accede to an offensive military treaty; the Treaty of Madras signed on 29 March 1769 had terms that each would support the other if attacked.

The British refused to assist him, even though they were also drawn into conflict with the Marathas in the 1770s. Hyder's battles did not fully end until 1779, when the Marathas negotiated an alliance with him and the Nizam for united action against the British. This led to the beginning of the Second Anglo-Mysore War in 1780. This conflict devastated much of the Carnatic, and also failed to decisively resolve differences between Mysore and the British. Resolution occurred in 1799 with the defeat and killing of Hyder's son Tipu Sultan, and the restoration of the Wodeyars as British clients.
