Answer the following question: Extract the answer to the question from the following context. Question: What did the British need to do because of peace with the French Context: In India, the British retained the Northern Circars, but returned all the French trading ports. The treaty, however, required that the fortifications of these settlements be destroyed and never rebuilt, while only minimal garrisons could be maintained there, thus rendering them worthless as military bases. Combined with the loss of France's ally in Bengal and the defection of Hyderabad to the British as a result of the war, this effectively brought French power in India to an end, making way for British hegemony and eventual control of the subcontinent.
Answer:
fortifications of these settlements be destroyed and never rebuilt
