Second Anglo-Mysore War (1780-1784)
• Haidar Ali accused the English of breach of faith and non-observance of the Treaty of Madras when in 1771 he was attacked by the Marathas, and the English failed to come to his aid.
• Haidar forged an anti-English alliance with the Marathas and the Nizam but the English detached both the Marathas and the Nizam from Haidar’s side.
• Haidar faced the English boldly only to suffer a defeat at Porto Novo in November 1781 but he regrouped his forces and defeated the English and captured their commander.
• The war was carried on by Tipu Sultan after the death of Haidar in 1782.
• Fed up with an inconclusive war, both sides opted for peace, negotiating the Treaty of Mangalore (March, 1784) under which each party gave back the territories it had taken from the other.
