Forrest's narrative takes readers to the captivating Mergui Archipelago, located on the eastern side of the Bay of Bengal. With meticulous detail and supported by maps and charts, he describes a 125-mile-long and 20 to 30 miles wide Strait, complete with mud soundings and predictable tides. This invaluable information provided a navigational route for ships to brave the South-West Monsoon, escaping the otherwise treacherous Bay of Bengal during the season. Beyond the archipelago itself, Forrest's account delves into the islands of Jan Sylan, Pulo Pinang, and the Port of Queda, shedding light on the current state of Atcheen. He also offers essential sailing directions from Atcheen to Fort Marlbro' along the captivating South-West Coast of Sumatra.
