They knew that the Moorish bow would be very effective within the range from 50 meters to 400 meters.
So when 40 Portuguese soldiers disembarked to face a first row of 300 archers also armed with tulwars, their first act was to run like madmen towards the archers, with their rapiers and left handlers in hand. The archers would be stunned by this totally insane act, as due to the heath, very few would wear armors. This stunning delay would again act in favour of the Portuguese who would close de 50 meters range with a few more seconds of advantage.
The Portuguese knew about the 50 meters bow effectiveness and that their only hope was to run frontward to cut that distance, after which their highly seasoned maneuver of the rapier and the left handler would destroy the tulwar in no time, one after the other. One blade would stop the tulwar strike and the other would dispatch the enemy, and this was one methodically in no time.
Running front wards for cover was a tactic that brought the Portuguese warriors great fame and respect for their bravery
It seemed that rapier with dagger in the war that can be good against one hand sword.
