Born in Middelburg, Putmans came to Asia in 1621 in the service of the Dutch East India Company.
In July of that year, in a surprise attack near the island of Gulangyu, near Xiamen, he managed to destroy the fleet that Zheng Zhilong was building there.
On 22 October, however, Putmans' fleet was defeated at the Battle of Liaoluo Bay, where Zheng Zhilong destroyed three Dutch East Indiamen with fireships and captured another, putting the remainder of the Dutch fleet to flight.
[2] Defeated in the battle, Putmans turned his attention to agriculture, establishing a policy of attracting settlers from the Chinese mainland to Formosa, in order to cultivate rice and sugar on the fertile plains on the west side of the island.
[3] In December 1636, Putmans returned to the Dutch Republic and, after an apparent spell in Amsterdam, settled in Delft in 1638,[4] where he would live until his death in 1654.
