The history of the Indian Navy can be traced back to 1612 when Captain Best encountered and defeated the Portuguese. This encounter, as also the trouble caused by the pirates, forced the British East India Company to maintain a small fleet at Swally, near Surat(Gujarat). The First Squadron of fighting ships arrived on 5 September 1612, forming what was then called the Honourable East India Company’s Marine. It was responsible for the protection of the East India Company’s trade in the Gulf of Cambay and the river mouths of the Tapti and Narmada. The officers and the men of this force went on to play an important role in surveying the Arabian, Persian and Indian coastlines.
