Answer:
Simply put, we can say that Hyder Ali did not defeat the British because he died and Tipu Sultan did not defeat the British because both he and his army were exhausted.
Explanation:
Hyder Ali and Tipu Sultan were indeed extraordinary warriors and were leaders of the Kingdom of Mysore in southern India. Hyder Ali managed to defeat the British army in several battles and in grand ways, but he died before the war ended and defeats the British army completely. After the death of Hyder Ali, Tipu Sultan assumed the leadership and despite the success of the army both he and the army were exhausted and tired of fighting and for that reason, Tipu Sultan preferred to establish the Treaty of Mangalor, which ended the war with England.
