Aungier embarked at Surat on 11 January 1670 and arrived in Bombay a few days later. The town was rife with many allegations of improprieties against Deputy Governor Captain Henry Young, and Aungier's immediate task was to investigate these allegations. He immediately set about defining the rules and regulations based on which Bombay must be governed and without which other reforms would be useless. Learning from the incessant perils of wars and tyranny being faced by traders in Surat, his first idea was that the city needed absolute peace and security. He therefore set out to set up the courts of Judicature and strengthening the fortifications of Bombay. He also initiated a survey of Bombay with a view of ascertaining the island's total land revenue. Although this trip lasted just under a month, it had set the foundations for future work.
