The following causes were responsible for the success of the British against the French:

1. Powerful Navy of Britain: The English navy was more powerful than that of the French. The British had large ships to bring soldiers and war material from England to India.

2. Sound Financial Condition of the British: Economic condition of the British was very sound. Their trade activities continued even during the war days. But as the French usually kept themselves involved in politics, they therefore, lacked financial resources.

3. British Victory over Bengal: Bengal, a rich state of India, came under the control of the British after the battle of Plassey. Need of money for winning a war is very great. The British trade in Bengal continued even during the war days. The money they earned from this trade was utilised by them for their wars in the south.

4. Efficient infantry and able army commanders: The infantry wing of the British army was better trained and organised than that of the French army. English commanders like Robert Clive, Sir Ayercoote and Major Lawrence were very capable persons. On the other hand, the French army commanders like Dupleix, Lally and Bussey were not so capable and efficient persons. This factor also contributed to the success of the British.
