Career
Benyon first arrived in Madras as a writer in 1710. In 1718, he was nominated to the council of Fort Saint George and served till 1725, when he resigned and returned to England. When George Morton Pitt resigned as Governor in 1735, Benyon, who was the seniormost member in the council was appointed Governor.
Benyon is regarded as one of the best Governors of early Madras.
He was one of the few early Governors who was not convicted of any charges. During Benyon"s tenure, the city saw rapid expansion.
The villages of Perambur, Sadayankuppam, Ernavore, Pudupakkam and Vepery were acquired from the Nayak of Poonamallee in 1739. The most important event of Benyon"s tenure was the invasion of the Marathas who invaded South India twice, once in late 1740 and the second time, in May 1741.
During the second invasion, the Maratha army under Raghoji Bhonsle invaded Trichinopoly, where the Carnatic general Chanda Sahib had set up his stronghold, while another occupied Fort Street David, Porto Novo and Sadras.
However, following the successful conquest of Trichinopoly and the capture of Chanda Sahib, the Maratha troops relinquished their conquests and quickly withdrew. All through this period, Benyon tried to coerce the Maratha generals by sending them presents. The fortifications of Madras were strengthened and all British, Portuguese and Armenian citizens of the city were forcibly conscripted.
