v4.c60.s5.2

The fort of Surat stood on the south bank of the Tapti, 12 miles from the sea. It was impregnable to a body of light raiders like Shivaji's troopers. But the city close to the fort offered a rich and defenceless prize. It had, at that time, no wall to protect it. Its wealth was boundless. The imperial customs alone yielded a revenue of 12 lakhs of Rupees a year (in 1666, according to Thevenot, v. 81.)
