History suggests that the maritime trade had greater interaction in this area and over the centuries, sub-continental coastlines have provided natural ports of call to the distant traders of the South East Asia and
The liberation of Bengali trade by the effective Mogul conquest of riverine Bengal also helped to strengthen shipping from
The Arakanese (Maghs) Pirates, the Ferringhees (Portuguese), Dutch and English renegades begun systematic piracy and robbery in the Sundarban area. With some small and light galleys they did nothing but coast about that sea, and entering into Sunderban through the rivers like Marjjal (now known as Zulfiquar channel), Malancha, Jamuna, Arapangsia and into the channels and arms of these rivers and between all these isles of the lower Bengal and often penetrating even beyond the Sunderban up into the countryside, surprised and carried away whole towns, assemblies, markets, feasts etc. They used to torch people and make women slaves great and small, with strange cruelty and burning all they could not carry away. Not a householder was left on the sides of the rivers and they swept it with the broom of plunder and abduction leaving none to inhibit a house or kindle a fire the entire tract. In a labyrinth of rivers the adventurers could dive and dart, appear and disappear, ravage the countryside and escape with impunity and hence this area has been the victims of exploits and depredations of foreign and native adventurers alike. For ages this area was known as Magher Mulluk due to terror created by the Maghs and the Portuguese armada. And probably there are seen in the mouth of Ganges/Sunderban so many fine isles quite deserted, which were formerly well peopled, and where no other inhabitants are found but wild beasts and specially tigers. Bengali rulers even built Forts in the confluence of Sibsa/Marjjal, Araibaki (Known as Ferringhee Fort) and Malancha and Jamuna. There are still channels in the Sundarban, which is known as Ferringhee Fari/Khal, Ferringheer Doania khal as these used to be places for heavy encounter with the Maghs, Arakenese pirates beside the confluence of Marjjal, Malancha and Pussur and Arapangsia.
Even foreign ships visited this port.
